The 7891 Listen Module was designed specifically for use with the ‘hybrid’ F/M-Type
console (F-Type input channels with M-Type group and Matrix modules). The F/M-
Type ‘hybrid’ is particularly suited to applications where ‘live’ recording is a principal
requirement. Since M-Type group and Matrix modules are fitted with “Listen”
switches that can route the main signal to a mono and/or stereo “monitor” bus, this
more specialised Listen module provides facilities for loudspeaker monitoring in a
control-room environment. The term “Listen” was retained (rather than “monitor”),
since the facilities are not the quite the same as on a console designed specifically
for recording.
The 7891 Listen Module has four sections. LISTEN 1 is a stereo monitor circuit,
designed to deliver its outputs to external amplifiers and loudspeakers. Channel PFL
can be routed to this section, but PFL is a mono signal. Separate volume controls are
provided to allow you to adjust the relative level between input channels and output-
modules and two switches allow you to ’mix’ the left or right listen bus to either out-
put.
Additional outputs for external metering are included plus two external inputs. Listen
1 has similar functions but is always ”mono”. The HEADPHONE section (at the top
of the module) has no direct connection to either Listen bus, but signals from the Lis-
ten 1 and Listen 2 circuits can be routed to it and this section also has external
inputs.The “Listen” switches on group and matrix modules, and the PFL switches on
group and matrix modules, and the PFL switches on input channels have two modes
of operation - mutually exclusive or additive.The mode control switches are mounted
at the bottom of the module.
