These jacks are used to connect a mixer or preamplifier to the A100. Connect to
either phone or the pin jacks, as appropriate. If both phone and pin jacks are
connected together, the signal fronh the phone jacks takes precedence.
* In a monaural (BTL) configuration, use the CH A jacks only.
e
Mode switch (MODE ST/MONO)
Use this switch to select either stereo or monaural operation. The A100 becomes
a monaural power amplifier with a rated output of 10OW (into 16 Ohm) when the
switch is in the MONO position.
Speaker terminals (SPEAKER CH A, B)
Connect the speakers to these terminals. When using the A100 as a stereo
power amplifier, connect speakers to both the CH A and CH B terminals. Be
careful not to reverse the polarity (+"), (-) at either the amplifier of speaker end
when making connections. Speakers with a rated impedance between 8 Ohm
and 16 Ohm should be used when the A100 is used as a stereo amplifier. When
using the A100 as a monaural amplifier, connect the speaker's (+) terminal to the
CH A (+) terminal and the (-) terminal to the CH B (+) terminal. Speakers with a
rated impedance between 16 Ohm and 32 Ohm should be used when the A100
is used in a monaural configuration.
To connect the speaker cables, check the polarity (+), (-) once again, then, while
pressing the terminal lever with your finger, insert the exposed conductor portion
of the cable Into the hole in the terminal and release the lever.
O AC power cord
Plug this power cord into an AC outlet. (Power requirements match local AC
voltage and frequency in area where sold.)
