COMP (Compensation)
Use the COMP switch to correct for phono
equalization introduced by the recording
process. The recording industry has agreed
to record all current LP and stereo recordings
with RIAA equalization. On earlier stereo and
on mono recordings use the position that
sounds best to you.
The MA230 TAPE switch makes it possible
to instantaneously compare recorded ma-
terial with the source signal. Use the MA230
TAPE switch to know instantaneously, as you
are recording, that the music on the tape is
acceptable. Tape monitor jacks on the back
panel accept a signal from a tape recorder
with a monitor head and preamplifier.
NORMAL . . . the original program source
is fed through the power amplifiers and the
loudspeakers.
MONITOR . . . the recorded sound on the
tape is fed through the power amplifiers and
speakers.
The PHASE switch corrects for loud-
speaker or program phasing. When this
switch is in the 180° position the phase in the
left channel is reversed.
