and source unit properly matched, consult your authorized ADCOM Car Audio
dealer.
Optimal performance and the advantages of “passively terminated
balanced" inputs are realized when sensitivity controls are turned fully
clockwise. Since the sensitivity controls affect only the positive inputs, the
controls MUST be fully clockwise in the MoSt ™ or mono configurations.
CARE AND CLEANING :
Great care has been taken by ADCOM to assure that your amplifier is
as flawless in appearance as it is electrically. In the event that your ADCOM
amplifier needs cleaning, use a damp cloth or dry, soft bristled paint brush. Do
not use cleaning fluids of any kind as damage to the finish may result. Treat this
product as a precision instrument, and it will provide you with many years of
musical enjoyment.
If you experience any problems with your ADCOM Car Audio amplifier,
please contact your local authorized dealer or call ADCOM Customer Service at
(908) 390-1130 between 9am and 5pm EST. Ask for Technical Assistance for car
audio.
SECTION 2: RCA Input Amps
INPUT SECTION:
It may seem unusual to find 4 RCA inputs on a 2 channel amplifier, but
that is just what you will find when you inspect the ADCOM GFA-4302 or GFA-
4402 amplifiers. Channel “A” is the “LEFT" and channel “B” is file “RIGHT”, The
inputs on the left side are the (+)positive inputs and the inputs on the right side
are the {-) negative inputs. If you wish to run these amplifiers in the Balanced
mode, it is strongly suggested that an authorized ADCOM Car Audio dealer
handle this installation!
There are two ways to run RCAs into these amplifiers. For stereo
operation. RCAs connect to the left-most input jacks, labeled A+ and B+. When
using the amplifier in either a bridged Mono or MoSt ™ configuration, t he upper
left and lower right inputs, labeled A+ and B-, are used. Always insert the
included RCA Shorting Plugs into unused RCA inputs!
