1 INPUT SELECTOR
Selects one of the seven inputs: CD, TUNER, PHONO/AUX 1, AUX 2,
AUX 3, TAPE 1, or TAPE 2.
2 RECORD SELECTOR
Selects between the program source (selected via the INPUT
SELECTOR), and either of two tape monitor inputs (selected via the
MONITOR SELECTOR).
In the DEFEAT position, the tape outputs are disconnected.
In the INPUT position, the tape outputs are connected while still
monitoring the selected source.
In the MONITOR position, the selected tape machine can be
monitored without affecting the signal at the tape outputs.
Note: Because of the switching arrangement employed in
the Nº28, we recommend that while making a critical
recording you don't operate the RECORD SELECTOR switch.
If you wish to monitor the signal from tape, set the RECORD
SELECTOR to MONITOR and use your tape machine's monitor
switch to switch between input and tape.
3 MONITOR SELECTOR
When the RECORD SELECTOR is in the MONITOR position, this selects
between the TAPE 1 and TAPE 2 inputs.
4 OUTPUT LEVEL
Adjusts volume at the main outputs.
The OUTPUT LEVEL control doesn't affect the tape outputs.
