A/D converter and clock setup (Only available if A/D converter module is installed)
Adcfs :
AdcOFF Adc Clk : Int Clkout : CkIN
The A/D converter / clock setup menu allows the user to configure the A/D converter sample rate and clock
routing. Use the DATA knob to scroll to the parameter you wish to modify. Press and release the DATA knob to
allow editing. Turning the DATA knob will then scroll through the available options for each parameter. Press
and release the DATA knob once again to finish editing.
The Adcfs field sets the rate at which the A/D converter will operate. In the “Off” position the A/D converter is
disabled and all clocks are turned off. When using an external clock be sure that the sample rate setting matches
the frequency of the incoming clock signal.
The A/D converter Clocksource field determines which clock is used to derive the A/D sample clock. WORD and
LOOP are the external clock sources and INTERNAL uses the on board crystal oscillator.
The ClkOut field determines which clock is routed to the m802 clock output. CkIn routes a buffered copy of the
incoming WORDCLOCK or LOOPSYNC clock to the clock output. Word routes the internally gener ated ultra-low
jitter wordclock to the clock output.
Digital Output Format
Digital
format:
cons Digital O/P : 1-wire
The digital output format menu allows the user to configure the data output format to indicate professional
(Prof) or consumer (Cons) in the digital stream. The digital O/P field selects between single wire (1-wire) and
dual wire (2-wire) operation. In single wire mode, the AES outputs function at the full sample rate and carry two
channels of digital audio data. In dual wire mode, the outputs run at half the sample rate and carry one channel
of digital audio data. Note that if 2-wire operation is selected here and the AD sample rate is set at 44.1 or 48kHz
the m802 digital outputs will revert to 1-wire operation. The physical output configurations for each of these
modes is discussed in the ”Digital Audio Connections” section
The Preamplifier ID
id:
1 peak : hld contrast : 126 backlight : on
This field allows one to select a unique identification for each preamplifier in a system. The ID number also as-
signs channel numbers to the preamplifier. For instance, ID 1 includes channels 1-8, ID 2 includes channels 9-16
and so on to ID 8, which includes channels 57-64. Pushing the DATA knob once allows the ID number field to
change by rotating the DATA knob. Pushing the DATA knob again saves the setting. When in MIDI control mode,
the ID setting determines which MIDI channel to which the preamplifier is assigned.
Note: It is very important that all preamplifiers in a multiple preamplifier system have unique ID numbers. How-
ever, the ID numbers do not need to be contiguous. For example, you could have one preamplifier set to ID1 and
another set to ID3. The result would be that in channel mode the RCU would page from channels 1-8 to channels
17-24. In meter mode (see page 19) you would see small dots over channels 1-8 and 17-24.
Peak Hold
This field sets the behavior of the bar graph meters. Selecting “off” turns off the peak hold function.
Selecting “dcy” sets the bar graph meters to hold the highest peak level for 3 seconds. Selecting “hld” stets the
meters to hold the highest peak setting until the PEAK button is pressed. The Peak hold settings can be adjusted
by pushing the DATA knob once and then turning the DATA knob until the desired function is visible. Pushing
the DATA knob again saves the setting.
