Link connector. Provides clock input and output for the T. Word input accepts sampling rates between 32 kHz and kHz. Word clock output is the rate that box is running. There is no sample rate conversion onboard the T. Unbalanced digital output, two-channel, for Output Bus 2. Signal source is menuselected.

Unbalanced digital output, two-channel, for the Master Output Bus. Signal source is menu-selected and is identical to the Analog Master Output Bus signal. When in the setup menu, the rotary switch moves between menu selections; push to enter selection or enter data. In record and playback modes, selects headphone monitor source; push action is user selectable. Accepts sources of 10—18 volts DC for unit powering and removable Li-ion battery charging. DC ground at both pins-1 and 2 is at the same potential as chassis and signal ground.

Also accepts batteries conforming to this mount. Numerous capacities, from mAh to mAh are available. Push down the pin with a long skinny object such as a key, screwdriver, or a pen. With the pin pushed in, slide the L- or M-Series battery to the right to release the battery. The T has four inputs and four record tracks.

Inputs can be analog or digital sources. Input sources are selected in pairs, 1, 2 and 3, 4. Each input pair 1, 2 and 3, 4 accepts analog or digital audio. The input signal type is selected using slide switch above the XLR input connector. The setup menu has additional input control. Manually selecting the audio source is used to force the inputs to analog while using an AES3 or AES3id input to lock the T to an external sampling rate. For most situations the appropriate setting is auto select—the T will choose the input type based on signal present.

The T is capable of off-speed sampling rates when clocked from either external digital inputs or the word clock input. This option shuts down all circuitry associated with an input pair to reduce power draw and extend battery runtime. Analog inputs 1 and 2, on XLR connectors, are the primary connections into the recorder. These inputs accept balanced or unbalanced micor line-level inputs.

When at mic-level, gain is controlled by the front panel potentiometers. Gain for the line level inputs can be controlled by the front panel potentiometers or menu settings. Line input gain is controlled in 0. A digital input present on the BNC inputs will override an analog signal present on the XLR inputs unless the input source is set to analog in the setup menu. In the setup menu, the following functions can be controlled for analog inputs 1 and Phantom power 48 volts can be activated for inputs 1 and 2.

When active, phantom is indicated by front panel LEDs. Phantom power is available for both micand line-level inputs. Using line-level inputs with microphones is useful in high SPL environments such as concert recording. Make certain to turn off phantom power with line level output devices susceptible to damage from DC. Shortcut : To toggle phantom power without entering the menus, press and hold the tone key then press the menu key for channel 1.

Channel 2 phantom can be toggled by pressing the tone key then pressing the HDD key. If the inputs are in line level mode, phantom power will not activate from the shortcut keys and must be activated from the menus. Phantom power is linked when the inputs are linked.

See Input Linking. Microphone inputs 1 and 2 each have a limiter circuit designed to prevent input overload. In normal operation, with proper gain settings, the limiters should rarely engage. When activated, these limiters will prevent unusually high input signal levels from clipping the analog input stage of the preamp.

Limiter activity is. The input limiters are active only with mic-level inputs. The limiters are engaged by factory default. Microphone gain is controlled by the front panel recessed knobs. Gain is controllable over two ranges, normal and low. The LOW range controls input gain from 9.

The fade to off options allow for fader-like control of your gain. When the high-pass is engaged on an input, its front-panel LED illuminates to indicate it is active. The high-pass is selected for each input independently.

Press and hold the LCD backlight key and press the menu key for channel 1 high-pass. When in line-level position, the gain for inputs 1 and 2 is controlled by the front panel recessed potentiometers or by a menu sensitivity setting. Analog inputs 1 and 2 can be linked as a stereo pair. When linked, the channel 1 front panel potentiometer controls the signal level of both inputs, and the channel 2 pot controls the left-to-right balance of the pair. When the inputs are linked, their peak limiters are linked, as well.

Input 1 is for Mid signal, input 2 for Side signal. Appearing on Switchcraft TA3 connectors, inputs 3 and 4 accept balanced or unbalanced linelevel signals. Gain resolution is in 0. Input level sensitivity for the line-level inputs is adjustable, in 0. While adjusting the input sensitivity, the meters will show the relative signal level present on each input on the meters. While channel 1 and 2 levels can be controlled by either the menu settings or the front panel pots, channels 3 and 4 are adjusted only in the setup menu.

The front panel digital input LEDs will illuminate when digital input is selected for the indicated track s. The T will auto detect the type of digital signal and adjust accordingly. To input analog audio while using the AES3id signal as a digital clock source, you must select analog in the input source menu selection for the appropriate inputs.

When a digital signal is present, the T will lock its sampling rate to the source frequency. This is indicated by a highlighted block on the main LCD display to the right of the bit depth and sampling rate indicators.

Recording bit depth is not affected by the external digital source. If you are locking the T to an external digital signal, be certain the source is stable. Loss of the digital signal will cause the T to revert to its internally set sampling rate, even while recording.

Once recording has begun, unused digital inputs are muted, digital signals that appear on them after the record key has been pressed will not be recorded or affect the sampling rate of the T. The four signal presence and peak indicators show audio activity before input-to-track routing. A digital delay is selectable on each channel of the T.

Delay time per input is selectable in tenths of a millisecond 0. The Rotary Switch and menu arrows are accelerated. The more you press or spin, the faster the time setting will increase or decrease. Delay is not set until the Rotary Switch is pressed or or the check mark is selected. The amount of delay available is dependent on the sampling frequency in use. Input delay can be useful for time aligning input signals from differing sources. For example, digital wireless mics that have a processing delay in their outputs.

In addition, all digital conversion stages have delay. The input matrix allows any input to be routed to any recording track. Multiple inputs can be routed to a single track to create mono-mixed recordings. The 4-by-4 blue LED matrix makes it easy to view the set routing. A solid blue LED indicates an input is assigned to a record track.

Hold down the STOP key then press the key to cycle through the six preset input-to-track routing combinations. These presets are factory set and cannot be changed. Press the EDIT soft key to enter the custom routing menu. Custom routing allows any input to be assigned to any record track. In the menu, highlighted input and track combination are displayed in white text.

The four inputs are shown on the left; the four record tracks are shown on the right. Press the EDIT soft button and scroll to the appropriate input screen. Using either the Rotary Switch or the up and down arrows, navigate to desired input-to-track combinations. Assigned tracks are noted on the screen by the addition of an arrow pointing to the record track. Once a track is assigned move to the next input-to-track combination desired. Exit and complete the assignment by pressing the check mark soft key.

The input routing menu will always exit to the main screen whether entered from the input key or the menu selection. This feature can be used to quickly mute microphones while maintaining their respective track assignments. The T LCD calculates available recording time based on the sampling rate, bit depth, number of tracks set for recording and the selected storage media available capacity. See the Calculating Recording Time later in this guide to estimate record time. When a sampling rate is selected for recording, all tracks are recorded at the selected sampling rate.

Sampling rates are selected among common rates from 32 kHz to kHz. Great units. Very good! A very perfect shopping experience. Eu ja trabalho com este equipamento. Skip to main content. About this product. About this product Product Information The T is an ultra-portable, four-track, file-based digital audio recorder. Known for pleasant sounding microphone preamps, the T is credited with frequency response linearity while maintaining very low distortion and noise.

No other recorder on the market matches its size, features, and durability. In addition, the T is designed to place an abundance of control in the hands of the user, while the menu architecture provides intuitive operation. Press the Rotary Switch or the enter key tone key to enter into edit mode. The user can set the time code numbers in pairs hours, minutes, seconds and frames.

To sync the T to a video camera, first determine if the camera is in drop frame or non-drop frame mode. If you, the DP or the producer are unsure about what setting to use, check with post-produc- tion, if possible.

If it is lit, wait until it goes out before removing the CF. This allows a user to record a take at a specific time from an unattended recorder. Files will play back in their order in the directory. Sound Devices Wave Agent Classic www. For iXML-aware software applications this data is available. Time is expressed in hours per track track-hours at the specified data rate supported by the T.

If recording two tracks, divide the track hours figure by two. Similarly for four-track recording, divide track-hours by four.

Time is expressed in hours at the specified MP3 supported by the T. Note that all recordings are two- channel recordings. Compressed Audio Take numbers can be overridden and a new take number can be set in the setup menu. Page Mono Track Name Designators Duplicate File Names When the T detects that a duplicate file name is going to be generated in any specific folder, the T changes the file name by adding of a letter suffix before the extension.

By default the folder where the last recorded file or played file is located with be the folder first opened. The T knows this file name by reading a. While it is possible to have thousands of files on the T storage volume s , the largest any single file may be is 4 GB. The T automati- cally splits an audio file before the 4 GB size is reached and begins writing to a new file.

When joined in an editing program, these files match seamlessly with no samples lost. If an error occurs during file copying, the T will prompt to cancel the transfer. When the destination storage medium is full, the T will report the error and end the transfer. Navigate to the file to be deleted. Take Status is used to mark the quality of the take so that post can quickly identify which takes to use.

The check mark appears in the selected box and the T automatically returns to the Main Display. Page Drive Type Formatting the drive prevents fragmentation and reduces the likelihood of directory cor- ruption.

Be certain that all files on the T drive have been backed up to another media before formatting. Once formatted, all data on the drive will be erased. Dynamic lists such as track names, scene names, folder options, etc Page Drive Failure The mechanical construction of the T is designed to minimize the transmission of shock to the hard drive.

The drive is isolated from the chassis using special shock-reducing closed-cell foam. This material increases the amount of shock the hard drive can withstand. Its speed, capacity, and price continue to evolve to the benefit of portable recorders.

The T can write to and read from CF cards as either its sole storage medium or simultaneously with the internal hard drive. Upon connection to an unformatted or non-FAT32 formatted external drive, the T will prompt the user to format the drive.

If the drive is already formatted as a FAT32 volume the drive will be ready to be selected as a storage medium. The front panel drive LED will illuminate to show which drives are available for recording. When connected to a computer, the internal hard drive and CompactFlash card of the T will mount to a Mac OS X or Windows computer as a local, removable mass storage volume.

Using Mac Finder, Windows Explorer, or any other file utility, files can be copied, read, and deleted directly to and from the T hard drive. If a future connection is going to be made the cable can be left connected. When the external DC reaches 9 volts, the T will automatically switch over to the removable battery. If no battery is installed the unit will shut down. Page Power-Up Messages The best determination of your run time is to experiment with a given record- ing setup.

The T power consumption varies over a range between 4 W to 20 W 12 volts , depending on ac- tive functions. The following functions have the most significant affect on power consumption: Inputs Active analog inputs increase power consumption.

Page Firmware Upgrades CF the recorder will prompt if the path is the proper file to use. Press the Rotary Switch or the tone key to say yes. The T will begin firmware upgrade and validation. When us- ing the CL-1, front panel controls and menu selections on the T can be mapped to keyboard short- cuts, allowing for full keyboard control of the recorder. Additionally the CL-1 has contact closures for programming remote inputs or outputs.
