Operate
Is the outboard power supply switched on, the Operate LED illuminates the cor-
rect work of the power supply. This LED needs 2 minutes delay. When the Mut-
ing LED switches off, the amplifier is ready for use.
Tape 2 Playback of recorder connected to the Tape 2 input
Bypass In this position the play input of tape 2 is bypassing the volume regulator. This is
indicated by lighting up the bypass and the tape 2 LED. The unity gain is set to
1 : 1 when the gain switch on the top of the preamp is set to “gain low”.
Tape 1 Playback of recorder connected to the Tape 1 input
Source Playback of the source that has been selected with the input selector knob [3]
If the Mode Selector is set to Source, you can record the source you are listen-
ing to via the two tape outs (Tape 1, Tape 2). To do this, Tape Copy [6] must be
switched off (see Section 3.2).
Muting You should mute the preamplifier outputs by
Connecting
turning the knob to the
Muting position (LED illuminates) before connecting or disconnecting source
equipment. The muting switch allows you to do this without having to switch the
Jubilee preamplifier off.

VOLUME CONTROL
Turn the volume control anticlockwise near to its zero position (close to 8 o'clock) before
switching on. High sound pressure levels can damage your hearing as well as your loudspeak-
