X-Rack Owner’s Manual
F.3.2 Monitor Section
The Monitor Section enables the Mix and Record busses or a stereo external input to
be monitored, the source to monitor being set by either the ‘MIX’, ‘REC’ or ‘EXT’
switches either separately or together, allowing great flexibility in recording and
monitoring signals. The ‘EXT’ input would normally be playback from the main
recorder or DAW. The selected monitor signals can be routed back to the Mix output
using the MON switch in the Mix Section, allowing composite mixes to be easily
recorded back to the master recorder or DAW ADC.
If one of the ‘SOLO’ switches on any other X-Rack modules is active, the ‘SOLO’
LED will illuminate and the AFLbus will be switched to the monitor output in place
of the selected signal. The level of the AFL signal can be adjusted with the ‘AFL’
control.
The overall monitor level is set by the ‘LEVEL’ control and the ‘MONO’ switch
allows quick mono compatibility checking. The ‘DIM’ and ‘CUT’ switches provide
either partial (between –3 and –30dB) or full attenuation of the monitored signal as
required.
Metering of the selected source (or sources) is provided by the stereo bargraph
meter which measures the signal level immediately prior to the ‘LEVEL’ control.
Two sets of stereo loudspeaker outputs plus a headphone amplifier are provided.
The headphone socket is driven by a fixed gain amplifier immediately post the
‘LEVEL’ control and is un-affected by the loudspeaker ‘ALT’ switch.
F.3.3 Expansion
Each of the three X-Rack busses (Mix, Record and Solo/AFL) are accessible
externally through the ‘MIX BUS LINK’ connector on the rear of the X-Rack.
Additional X-Racks can be connected via this connector, allowing additional inputs
to be mixed together and feed a single Master module. The pinout for this connector
is detailed in Section 5.2 of the X-Rack Owner’s Manual; if the connector listing is
not present in your manual, a more recent copy may be downloaded from the Solid State Logic website
(www.solid-state-logic.com
).
Only one XR622 master module is required per system – connecting two or more X-Rack units fitted with
XR622 modules together will cause serious gain errors and distortion (though it will not damage the system
electronics).
