ARCHITECT’S
SPECIFICATIONS
An audio control console designed for
simultaneous language interpretation in
presentation-style conferences, where a
floor and a single relay language are used.
A single audio control console shall allow
one or two interpreters to monitor floor or
relay sources, activate microphone inputs,
and route the interpretation to one of two
audio output channels or to the relay bus.
The audio control console shall have
daisy-chain capability to connect up to 4
consoles using CAT5 cable for the relay bus,
eliminating the need for external distribution amplifiers.
The SL Interpreter is a compact
and stand-alone audio control center for
simultaneous interpretation of one or more
languages. It allows one or two interpreters
to monitor floor or relay sources, activate
microphone inputs, and route the interpretation signal to differnet outputs. Ideal for
presentation-style conferences, where a
floor and a single relay language are used. Recommended to be used with Sennheiser Tourguide
2020 or 1039.

ARCHITECT’S
SPECIFICATIONS
The top panel of the audio control console
shall feature individual headphone volume
and tone (bass and treble) controls for
two interpreters and shall also have two
separate “Mic On” buttons to activate the
microphone. The audio control console
shall provide two separate “Floor Input”
and “Relay Input” buttons to select the
listening mode (headphones monitor
the floor channel or the relay channel)
and one “Channel 1/Channel 2” button
to switch the microphone output from
channel 1 (default) to channel 2, the relay
channel for each of the two interpreters.
In addition, one “Mute” (cough) button
shall be provided that mutes the active
microphone.
The back panel of the audio control
console shall be fitted with the following
inputs, controls, outputs and switches: one
XLR-3 socket (Floor In) for connecting balanced or unbalanced audio signals from a
PA system, mixing console or microphone,
one XLR floor level control for setting the
input level of the XLR-3 socket, one RJ-45
input (Link In) and one RJ-45 output (Link
Out) for daisy-chaining multiple consoles
and routing the floor and relay signals
between the consoles via CAT5 bus cables,
two XLR-3 outputs (XLR CH2 and XLR CH1
output) for routing balanced line-level
signals to a transmitter, two RCA outputs
(RCA CH2 and RCA CH1 output) for recording or playback of the interpretation, two
feed-through switches (CH1 and CH2 feed
thru) that, when set to “ON”, automatically route the floor channel to any unoccupied channel and one ground lift switch
for eliminating ground loop problems.
The XLR-3 CH2 output and the XLR-3
(Floor In) input shall be internally connected to the RJ-45 output (Link Out) so
that, if channel 2 is the selected output,
both the floor channel and channel 2 are
available on the audio bus.
