MODE CONTROL
The MODE button has the following functions:
• It activates the preamplifier from Standby.
• Pressing the MODE button once with the preamplifier activated will mute the volume level by 20dB. The
MODE indicator light will glow ORANGE. The amplifier remains fully functional in this mode. Another single press
unmutes the preamplifier and the MODE indicator light will revert to RED.
• With the preamplifier activated, a sustained press on the MODE button, reverts it into Standby with all the
input indicator lights extinguished and the MODE indicator light GREEN.
NOTE: When you bring the Caspian preamplifier out of STANDBY having switched it ON at the Mains, the input
selector will default to CD (as described previously).
When, however, the preamplifier has been put into Standby from the MODE button, bringing it out of Standby will
restore previously selected input, tape and mute values. Bringing the preamplifier out of Standby by moving the
INPUT Selector one step in either direction also leaves these amplifier settings unaffected.
INPUT SELECTOR SWITCH
The INPUT Selector is an endless rotary switch that moves round one click at a time. It connects each signal
source to the amplifier by rotating through the Inputs with the exception of TAPE. Rotating the Selector
continuously clockwise will select inputs in this sequence:
CD – TUNER – VIDEO – LINE1 – LINE2 – CD - …
Rotating the Selector anti-clockwise reverses the sequence.
Whenever an input is selected the appropriate indicator light will glow.
VOLUME CONTROL
The VOLUME Control is a precision device. It follows a logarithmic law so that its response approximates that of
the human ear and provides more control (range) at lower levels. There is an illuminated indicator on the volume
control to clearly show the appropriate volume setting.
TAPE MONITOR
When you select an input source, the INPUT Selector connects the selected source to the preamplifier and also
connects this source to the Tape Output Sockets of the Caspian thus enabling you to record.
The Tape Monitor is an override. Pressing the TAPE Button (10) connects the output of your tape deck to the
Caspian, overriding the selected input. However, the selected input is left connected to the recording input of
your tape deck. If you have a suitable tape deck, this facility enables you to record a programme whilst
monitoring its playback.
When the TAPE Button is depressed, the TAPE Indicator light glows and the selected source Indicator remains
illuminated.
The input selector remains functional when the Tape Monitor is ON, allowing a range of sources to be recorded.
Pressing the TAPE Button toggles between Tape Monitor ON and OFF.
