Input Linking (Stereo or MS Decoding)

Inputs 1-8 can be grouped or linked together to ensure that gain is applied evenly across all linked
inputs. Linked or grouped inputs can also be muted and un-routed from tracks by using a single
Input Trim Pot. Input settings such as Input type, Limiter, Phantom Power, and High-Pass Filters are
also linked and will be applied across all linked inputs.
Neighboring inputs can be linked as stereo pairs in the following sequences: 1-2, 3-4, 5-6, and 7-8.
When linked, the odd Input's trim controls the signal level of linked inputs, and the even Input's
trim controls the left-to-right balance of the stereo pair.
When set to link as an MS pair, the inputs are decoded as MS stereo, where the gain and balance for
the pair work the same as stereo linking above. The odd input is for Mid signal and the even input is
for Side signal.
When linked, the Input Selector Switch will solo the linked pair in the headphone monitor. For
example if Input 1 and Input 2 are linked as a stereo pair, pushing the Input Solo Switch will change
the headphone monitor to 1,2 (Input 1 on the left-side and Input 2 on the right-side of the headphone
monitor).
When a CL-8 is attached or the Setup Menu option INPUT: FRONT PANEL CONTROLS is set to Fader
Controls, the odd Fader will control the post fade signal level of the linked pair and the even fader
will be disabled.
If MS stereo linking is selected for inputs, program sent to tracks and headphones will be L/R stereo pro-
gram. To record discrete M and S signals, do not link for MS, but monitor the MS signal in headphones.

Digital Inputs

The 788T accepts AES3 (AES/EBU) balanced and AESid unbalanced digital signals in professional
or consumer format via its DE-15 connector. The 788T will auto detect the type of digital signal and
adjust accordingly. Digital input gain is controlled via the front panel potentiometers.
To use a digital input, the Input Type switch located in an input's Input Settings Window must be set
to Digital. Although a digital input signal contains a pair of inputs, the 788T is able to select just one
of the pair as an input, so for example, it is possible to select line or mic for Input 1 and digital for
Input 2.
When recording from a digital input, it is important to sync the 788T's sample clock from a source
that is synchronous with the digital input signal otherwise audio quality will be degraded.
chronization. The simplest way to achieve this is to set the 788T to derive its sample clock from the
clock embedded within a digital signal. Go to the REC: SYNC REFERENCE Setup Menu and set the
sync source to the applicable digital input pair.
The LCD will display 'D' when locked to the selected digital input. If the Input Activity ring LEDs
are fl ashing, then a digital input is selected but no valid digital clock is being received.

AES42 Digital Microphones

The 788T is compatible with digital microphones conforming to the AES42 specifi cation, 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.
Never apply digital phantom to unbalanced digital inputs, as this can result in damage to the hardware.
