of Warm-up will restore previously selected input, tape and mute values. Bringing the M2 out of Warm-up 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 above 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. There is an illuminated indicator on the volume control to clearly show the appropriate
volume setting.
When you select an input source, the INPUT Selector connects the selected source to the amplifier and
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
M2, 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.
If you suspect your ROKSAN M2 CD Player is not operating properly, first check all the connections carefully.
Pay particular attention to input and output connections. RCA plugs should be fully inserted- a frequent cause
of problems is that RCA plug surrounds do not make proper contact. Below are some commonly encountered
problems with suggestions for possible cure. The list is not exhaustive: If you have any unresolved problems,
please consult your appointed ROKSAN dealer or distributor.
