9.) MASTER-SLAVE MODES
A module may operate in either master or slave mode. The slaves copy parameters set on the master to their
immediate left.
A
Master module
is located in the leftmost chassis position and set to “master” via its internal DIP switch
(position 1 set to “ON”). All the other modules can be set to “slave” (using each one’s DIP switch- position
1 set to “OFF”).
Slave module
parameters may be programmed independently via the slave module’s own front panel
switch. However,
the master-slave relationship will override such settings
; the next time the master
module parameters are programmed, the settings will change immediately on all the slaves as well. So if
you want to program different settings on Slave modules, be sure to program the
MASTER FIRST
. When
the frame is powered “ON,” the slaves will always emulate the nearest master module.
●When the power is turned on, the -9dB lamps will remain steady on slave modules.
The -9dB lamps will flash for a few seconds on any master modules.
See the “Settings” section (below) for DIP switch location.
B.) M•AD-824 SETTINGS
EXTERNAL SETTINGS on M•AD-824 front panel:
Wordlength
selection between 24, 20 and 16 bits
Analog soft saturation
, “rounding off signal peaks” to enable driving the ADC harder for extra hot
recording
Digital soft saturation
, emulates tape saturation – enabling 6dB hotter operation for signals under -
12dBFS
Reference Meter Bridge
with –10, -12, -14, -16, -18 and –20dBFS reference points
Peak-Hold
, to hold and indicate the highest peak indicated by the meters. It is reset when quickly operating
the front panel switch
Dither
, for proper truncation to 20 or 16 bit word length.
ABC-1
and
ABC-2
, similar to dither, but with added noise-shaping processing.
The various parameters are retained in a non-volatile memory; thus, turning the power on will restore the
last set of parameters programmed by the user
INTERNAL SETTINGS:
The M•AD-824 has a number of internal settings, which can be accessed by removing the top cover (please
see “Opening the LavryBlue” Page 20).
There is a “DIP switch” located on the M•AD-824 PC board that controls a number of parameters. There is
also a “jumper” which can be used to set the threshold for Analog Saturation mode.
The
polarity
of the XLR inputs on the M•AD-824 is configured at the factory for:
Pin 2 “+” (non-inverting) & Pin 3 “-” (inverting)
It is possible to switch the
polarity
to Pin 2 “-” & Pin 3 “+” by changing the setting of the DIP switch
Position 2 from “OFF” to “ON.”
