8.3 Input State
The 8 level meter of the
INPUT STATE show the digital value (dBFS) of the input level per
channel. The level data incorporate Input Trim and Digital Limiter. The red LED OVR is lit 0.2
dB before full scale level (-0.2 dBFS).
With activated
METER GR AUTO the amount of Gain Reduction is shown in dB as bar from top
to bottom, as soon as the Limiter becomes active. In case of overload a display is even per-
formed when the Limiter has not been activated, because the Limiter is indeed always active,
operating at a threshold of +3 dB.
When the Setup menu is active, the according parameter values are displayed in this level me-
ter window.
8.4 Meter
METER PH provides a Peak Hold function for all level meters, either
permanently ( ON ) or switched off by Auto Reset ( AR ) after 3 seconds.
In mode ON, a reset (erasing the current peak values) is issued by a
single push of the PH button. The function itself is not changed.
8.5 Remote
REMOTE defines the source of MIDI remote control commands. Choices are
the MIDI DIN jack, AES1 and the MADI input of the I64 MADI Card (Option Slot).
Note: Via MIDI remote control, all front panel controls can be locked (Lock
Keys). An exception is the REMOTE key. In the Off state (no LED lit) Lock Keys
is deactivated. Therefore a locking of all the controls can be revoked directly at
the unit at any time.
8.6 Clock Section
The source and frequency of the unit's clock is configured in the CLOCK SECTION. The button
CLOCK lets you step through the options external clock (Word, AES, Option = MADI) and inter-
nal clock, and sets the sample rate for both an external and the internal clock.
WCK, AES, OPTN (Slave Mode)
Defines the corresponding input as clock reference. A missing or invalid clock source signal is
indicated by flashing of the corresponding LED.
INT (Master Mode)
Activates the internal clock.
With a setting of INT (internal clock) it is mandatory that the clock rate of the sources is
synchronous to the ADI-8 QS. Therefore the external device has to be synchronized to the
ADI-8 QS word clock output or AES/ADAT/MADI output.
The ADI-8 QS thus has to be master, all devices connected to it must be slave. In order to avoid
clicks and drop outs due to faulty or missing synchronicity, a special process called
SyncCheck
compares the incoming data and the ADI-8 QS internal clock. The SYNC state is indicated by a
flashing (error) or turned off (OK) LED.
