REMOTE TURN-ON JACK

1

8

" “mini” jack above the AC mains receptacle on the rear panel allows

remote-controlled turn-on (that is, toggling between operate and
standby) of the Proceed AMP. This remote “trigger” will be operated by a
3–12 volts DC positive-polarity pulse, of at least 100 milliseconds dura-
tion, with tip polarity as shown below:

3-12 volts for at 
least 100 mS

Your Proceed dealer can help you take advantage of these design features
to maximize your system’s versatility.

AC MAINS FUSE

One fast-blow fuse is located on the rear panel of the AMP. If it should be-
come necessary, replace the fuse with the same type only. Refer to the fol-
lowing table for replacement values.

SPEAKER BINDING POSTS

The Proceed AMP is equipped with gold-plated, high-current  binding
posts for output termination to a loudspeaker system. To take full advantage
of the AMP’s sonic quality, we recommend using high-quality speaker cable;
see your Proceed dealer.

Caution!

NEVER connect the Proceed AMP output terminals to any
device other than a loudspeaker.
NEVER short-circuit the amplifier's output terminals.
NEVER connect the left-channel output terminals to the right-
channel output terminals.

There are two recommended methods for connecting speaker cables to the
Proceed AMP. A high-quality spade lug or hook lug, soldered to the cable
(or crimped with extremely high pressure), is best.
