NOTE: Using different preamp VOLUME CONTROL settings
changes the THRESHOLD and LEVEL MATCH settings.
Graphic Equalizers
If you use a graphic equalizer with your hi-fi, the equal-
izer must not be connected between the 128’s RECORD
OUTPUTS, and the tape recorder’s inputs, or between the
recorder’s outputs and the 128’s PLAY INPUTS. Ideally the
128 can be installed in the tape monitor loop, and the
graphic equalizer installed between the preamp output and
the power amplifier input (Figure 6 ).
Equalized Speaker Systems
If you have an equalized speaker system, such as a Bose
or Electro-Voice ‘‘Interface: A,” then the 128 should be con-
nected in the tape monitor loop of the speaker equalizer and
the equalizer should be installed in the tape monitor loop of
the preamp (Figure 7 ).
Note: Never connect any other electronic equipment between
the 128 and your tape recorder inputs. This could cause in-
accurate encode/decode tracking and loss of quality in the
recorded signal.
