S2-CSE Dual Stereo Line Input with EQ Channel
This channel is the Dual Stereo Input channel as above but tted with equalisation,
providing 7dB cut and boost at HF (6.5kHz) and LF (100Hz).
S2-CSG Stereo Line with Gram Input Channel
This channel is the Dual Stereo Input channel tted with a RIAA input amplier on the
second input. Input connections for this are unbalanced on phono sockets. This channel is
also available with equalisation, type number S2-CSGE.
S2-CDS Digital Dual Stereo Input Channel
The Digital Dual Stereo Input channel has two 24-bit 96kHz digital inputs with a button
switch to select between them. Either input can be congured to be balanced AES/EBU on
standard XLR, or S/PDIF on phono sockets, selected by internal jumpers. The digital signals
are converted to analogue and from this point the channel functions are the same as the
Dual Stereo Line Input channel.
S2-CDSE Digital Dual Stereo Input with EQ Channel
This channel is the Digital Dual Stereo Input channel as above but tted with equalisation,
providing 7dB cut and boost at HF (6.5kHz) and LF (100Hz).
S2-C6SS 6 Way Stereo Line Source Select Channel
The 6 Way Stereo Line Source Select channel has 6 balanced stereo inputs on a 25 way
D type connector selectable by a 6 way mechanical interlocking switch bank. The switch
bank also controls 6 sets of remote outputs allowing each source to have a set of start/stop
remotes. The channel is tted with EQ as standard and other functions similar to the dual
stereo input channel.
S2-CT Telco Input Channel
The Telco Input channel controls the connection to the telephone balance unit (hybrid).
It has only one mono input with EQ tted as standard. Equalisation is enabled by the EQ
button, providing 7dB cut and boost at HF (6.5kHz) and LF (100Hz). A Pan control is available
to facilitate stereo imaging. A balanced line level output is provided for the cleanfeed back
to the hybrid.
Channel coarse gain is set by an internal preset and ne gain is trimmed by the front panel
Trim control providing ± 12dB of gain. The channel has a Pre Fade Listen (CUE/PFL) facility
that automatically routes talkback to the caller when selected. PFL can be automatically
disabled when the fader is opened. There is a logic remote output to place the hybrid “on
hold” by using the LINE HOLD button. The remote output on the 9 way D type plug is fed
from an NPN opto-isolator.
The bus system allows for two true cleanfeed systems when routed to the PGM outputs. O
line phone conversations can be recorded via the AUD bus where a cleanfeed is generated
by the mix-minus method.
