The New and Improved Take List

Wildcat introduces a new and improved ﬁle management system. All metadata edits and entries are

now performed in the Take List and are applied across all available media that contain the select ﬁle.

The Take List is accessed via the Setup Menu option FILE: VIEW TAKE LIST or by simply pressing

the HDD key.

The File Viewer (Drive Directory) (formerly accessed by pressing the HDD key) is now

accessed by pressing the soft DRV (HDD) key from within the Take List or via the Setup Menu

option FILE: VIEW FILES.

The Take List contains a list of every Polyphonic or Monophonic take that has been recorded by the

788T. Takes must be recorded with Wildcat Beta or greater in order to view them in the Take List.

The name of the take is displayed on the left hand side of the Take List. The right hand side of the

Take List displays additional ﬁle information. The type of information displayed can be toggled

by pressing in on the Multi Function Rotary Switch. Each press will toggle between the following

information.

• Beginning time code stamp

• Time of ﬁle creation

• Date of ﬁle creation

• Scene name

• Drives that contain the ﬁle

• Folder that contains the ﬁle

The following functions are performed within the Take List.

• Increment/Decrement Scene and Takes

• Edit metadata and rename ﬁles

Duplicate Takes

With the ability to rename ﬁles and edit scene names directly from the 788T, it is possible to generate

ﬁles with duplicate ﬁle names. In this event, the 788T will detect that a ﬁle with the same name

already exists and will ask the user if a duplicate ﬁle should be created. If the user selects to do so,

the resulting ﬁle name will be pre-ﬁxed with a +. If this occurs for more than two ﬁles, an additional

+ will be added respectively for every ﬁle generated or altered.

Setup Menu Option Time Code: Hold Off

In the industry there are a wide variety of time code generators. Time code streams are standard

from device to device; however, the start and stop sequence of the time code stream can differ.

Because of this, the 788T recorders were susceptible to generating unintentional takes when in

EXT TC - Auto Record or EXT TC/CONT - AUTO RECORD modes.

Time Code Hold Off is designed to eliminate unintentional takes from occurring. The user can

now determine a duration in which a valid external time code signal has to be detected before the

recorder generates a new take. The value of Time Code Hold Off needed is dependent on the start

and stop sequence of the master time code source.

To use the Time Code Hold Off feature:

1. Access the Setup Menu option TIMECODE: HOLD OFF.

2. Set a value between 0 and 8 seconds in .1 second increments using the soft Up and Down Arrow (Menu

and HDD) keys or the Multi Function Rotary Switch. 2.0 Seconds is the factory default.

3. Save the selected value by pressing the soft Check Mark (Tone) key or by pressing in on the Multi

Function Rotary Switch.

4. Exit the Setup Menu by pressing the soft X (Brightness) key or the Stop key.

5. Begin rolling time code from the master time code source.

6. The 788T recorder will display the Record Pending message immediately after detecting a time code

signal.

7. When the selected Hold Off value has elapsed, the 788T will begin recording.

Things to consider when using Time Code Hold Off:

• This feature only applies to EXT TC - AUTO RECORD and

EXT TC/CONT - AUTO RECORD modes.

• If Pre-Roll is set, it will be applied. Pre-Roll will only capture audio from the initial detection of

a time code signal. If no Pre-Roll is selected, the ﬁle will begin after the Hold Off time expires.

It is best practice to set Pre-Roll, in the Setup Menu option REC: PRE-ROLL TIME, to a value

greater than the selected Hold Off value. This ensures that audio is captured from the moment

a time code signal is detected and unintentional ﬁles triggered by short bursts of time code are

not generated.

788T User Guide Addendum

Sample Rate Converters Enabled

The 788T includes automatic high-quality sample rate conversion (SRC) on the AES/EBU digital

inputs. Because of the automatic SRC, any digital input can be fed with any sample rate (from

32k to 192k) while the 788T is clocked off of its internal sample rate. One of the beneﬁts of the

automatic SRC is that each digital input can be fed from a different source without having to word

clock all of the devices together. The SRC is only enabled when needed, when it is not needed

it is turned off: When the user wishes to use the digital inputs without the SRC enabled, the

REC: SYNC REFERENCE can simply be changed to either the Wordclock Input, Video Input or the

desired Digital Input.

AES42 Support

The 788T is compatible with digital microphones conforming to the AES42 speciﬁcation, such as the

Schoeps CMD-2U. By setting DIGITAL INPUT: AES42 POWER to Enabled, the 788T supplies +10V

of “digital phantom power” to each of the digital inputs. The gain of the microphone can be adjusted

with the 788T’s front panel gain control just like a normal analog microphone. The gain adjustment is

controlled in the 788T digital domain.

Things to consider when using AES42:

• The 788T supports four AES42 pairs.

• Input Limiters can not be enabled for Digital Inputs.

• The 788T supports digital audio transfer via AES42. It does not support the AES42 protocol for

remote control or identiﬁcation of microphone type and settings.

Additional Control of the Input Limiters

The 788T offers several adjustments for its peak limiter to tailor the sound to the user’s desire:

Threshold; Knee; and Recovery. The threshold adjusts the maximum peak level at which the limiter

limits. Sounds louder than this threshold are attenuated.

The recovery adjusts how slowly the limiter brings its gain back up after a peak is limited. A shorter

recovery follows the envelope of speech better than a longer recovery, but at the expense of low-

frequency distortion. The Setup Menu option INPUT: LIMITER RECOVERY is now adjustable from

50 msec (reduced from 200 msec) to 2000 msec in increments of 10 msec.

Wildcat adds a Setup Menu option INPUT: LIMITER KNEE, which allows the user to control

whether the limiter has a Hard- or Soft-Knee. The hard knee setting leaves all program material

below the threshold completely unaffected and attenuates only those peaks above the threshold. The

soft knee setting attenuates the program material slightly before the threshold (about 6dB) for a more

gradual tape-like sound.

Headphone Monitor Changes

Wildcat improves the overall performance of the Headphone monitor. Gain is now adjustable from

Off, -40 dB to 26 dB in 2 dB increments. This increases the amount of gain that can be applied to the

headphone monitor and it also improves the overall gain curve.

788T User Guide Addendum

v. Wildcat Beta Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.

To help protect the ears of all 788T users, a brief mute is applied to the inputs when Phantom Power

is engaged/disengaged. The gain level of the various headphone bells has also been reduced.

At the request of many 788T users, we have added a few additional headphone monitor modes.

• LR, LR

• LRA, LRA

• LRB, LRB

• LRC, LRC

• LRD, LRD

• LRE, LRE

• LRF, LRF

Control of the LCD Backlight Mode

Wildcat allows the user to defeat the LCD backlight by color in the Setup Menu option

LCD: BACKLIGHT MODE. By Factory Default the LCD backlight will be White in Standby, Green in

Playback, and Red in Record Modes.

White/Green/Red This is the Factory Default setting. The backlight will illuminate White in Standby, Green upon

Playback, and Red upon Recording.

Red on Record Only The LCD backlight will illuminate Red during Recording and White for Standby and Playback..

Green on Play Only The LCD backlight will illuminate Green during Playback and White for Standby and Record..

White Only The LCD backlight will remain White at all times.

Power LED Changes

The Power LED now indicates charging activity at all times.

Power LED Activity Description of Activity

Off Unit is Off, charger is disabled

Solid Amber Unit is Off, battery is fully charged

Solid Green Unit is On, battery is fully charged or detached

Solid Green/Flashing Amber Unit is On, battery is charging

Flashing Amber Unit is Off, battery is charging

CL-1 Remote Control and Keyboard Interface Support

The CL-1 Remote Control and Keyboard Interface is an available hardware accessory to interface

with PS/2 compliant computer keyboards and enable external devices to control the 788T. When

using the CL-1, front panel controls and menu selections on the 788T can be mapped to keyboard

shortcuts, allowing for keyboard control of the recorder. Additionally the CL-1 has contact closures

for programming remote inputs or outputs. These are commonly used for machine control and

“remote rolling” using a mixing console with transport controls.

Connecting the CL-1

1. Connect the included C. Link cable to the 788T’s C. Link Input connector.

2. Connect the opposite end of the C. Link cable to the CL-1’s C. Link connector.
