or counter-clockwise will execute the store function. The display will briefly display "*** Confirmed ***"
and then return to the Channel Mode.
Note: A preamplifier will automatically store all of its current settings into a non-volatile memory when-
ever power is removed. When power is restored the preamplifier will retrieve these settings. This ensures
that no settings are lost during power line interruptions.
Preset Recall:
*recall preamp preset*
Registers 1 through 15 are available for user storage and recall. Register number 0 cannot be over-
written and contains a "null" set-up. The "null" setup sets all channels to the lowest gain setting, mic
power off, phase reverse off, mic input to 48V and deletes any channel groups. Pre-set register 0 is
helpful when setting up for a new session. Recalling a preset is identical to storing a preset (see Preset
Store above).
A/D converter and clock setup (Only available if A/D converter module is installed):
Adcfs :
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 con-
verter 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
The digital output format menu allows the user to configure the data output format to indicate pro-
fessional (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 Connec-
tions" section
