Stereo-mono switching
Stereo-mono switching in the audio amplifiers may be
performed for radio, disc, or tape programs by means of the
STEREO, MONO L, MONO R, and MONO L+R mode
buttons.
STEREO button depressed - the two channels are separated
for stereo reproduction.
MONO L button depressed - the left channel program is fed
to both speakers.
MONO R button depressed - the right channel program is fed
to both speakers.
MONO L and MONO R buttons simultaneously
depressed — the two channels are separated for stereo
reproduction, with the channels crossed over. This is a two-
fingered operation because you must prevent the first button
jumping out when you depress the second button,
MONO L+R button depressed — the two channels are
mixed together and fed to both speakers (this is normal full
mono operation).
The diagrams illustrate the five possibilities.
Use of PRE AMP OUT and MAIN AMP IN
sockets
The four sockets on the extreme left of the back panel give
access to the pre-amplifier outputs and the power amplifier
inputs.
The sockets are intended for connection of external networks
such as equalizers, echo boxes, and reverberation units.
NOTE!
For normal use the sockets must he strapped together with U
links as shown in figure (a).
When an external network is required between the PRE AMP
output and the MAIN AMP input, remove the U links and
connect according to figure (b).
The PRE AMP output provides approx. 2 volts at less than
0.1% distortion and has a source impedance of approx.
1 k ohms.
