INPUT A This provides a pair of RCA phono sockets for connection to stereo sources.
Channels 5,6,9,and 10 provide RIAA equalisation for magnetic cartridges to connect up
to 4 turntables (record decks). Make sure the turntables are correctly earthed by
connecting their earth straps to the console chassis earth terminal. Channels 7 and 8
inputs are unbalanced and can accept line levels signals from as low as –10dBu to a high
+10dBu for to connect stereo equipment such as CD and MiniDisc players. The level is
matched to the console using the front panel GAIN control.
INPUT B This provides either a pair of TRS jack or RCA phono sockets for connection
to line sources. Channels 5 and 10 provide RCA phono sockets for connection to stereo
sources. Channels 6,7,8 and 9 provide TRS jack sockets. For stereo sources plug into
both the L/M and R sockets. For mono sources plug into just the L/M socket leaving the
R socket unplugged. In this case the signal is normalled through the R socket to the right
channel. The jack inputs are balanced to provide interference rejection when connecting
to 3 wire balanced sources using long cables. The socket automatically grounds the cold
(-) input to accept unbalanced 2 wire TS jack sources. To connect an unbalanced source
using a TRS jack you should link ring to sleeve in the plug as shown above. The inputs
can accept line level signals from as low as –20dBu to a high +10dBu. The level is
matched to the console using the front panel GAIN control.

EXT IN This provides a pair of TRS jack sockets for connection to line level sources such
as effects, 2-track or monitor returns. Tamperproof front panel switches determine
whether the signal feeds Mix1, Mix2 or both, or just the monitor select switch bank. For
stereo sources plug into both the L/M and R sockets. For mono sources plug into just the
L socket leaving the R socket unplugged. In this case the signal is normalled through the
R socket to the right channel. The inputs are balanced to provide interference rejection
when connecting to 3 wire balanced sources using long cables. The socket automatically
grounds the cold (-) input to accept unbalanced 2 wire TS jack sources. To connect an
unbalanced source using a TRS jack you should link ring to sleeve in the plug as shown
above. The operating level is –10dBV but may be set for +4dBu by changing an internal
link option.
