A275
INSTALLATION MANUAL
Chapter 1: Introduction
Thank you for purchasing the ATON A275 Two-Channel Power Amplifier. Soon you will be experiencing the quality and reliability we
place in all of our products. The backbone of any distributed audio system is the amplification. The true test of any amplifier is the abil-
ity to drive multiple speakers at low impedance for hours on end. In this arena, the A275 excels! Heat is the number cause for amplifier
failure, or temporary audio loss from thermal shutdown protection circuitry, a.k.a. overheating. Of course that typically happens when
you are entertaining a house full of guests! ATON designed the A275 with 2 long rows of external cooling fins to increase the heat dis-
sipation capability. Higher cooling capacity equals longer product life, cleaner audio signal, and of course, more satisfied customers!
A275 Features
• 2 x 45 Watts per Channel @ 8 Ohms
• 2 x 75 Watts per Channel @ 4 Ohms
Buffered Line Outputs
• Allow the signal to be sent to other A275 amplfiers, A/V receivers, etc.
System Trigger In/Out
• SYSTEM TRIGGER IN allows all channels of the amplifier to UNMUTE when a signal is received.
• SYSTEM TRIGGER OUT sends a +12VDC pulse whenever any of the channels of the amplifier are UNMUTED.
Individual Channel Level Adjustment
• Fine-tune each channel’s level using precision potentiometers.
5-Way Speaker Binding Post
• The A275 is equipped with gold plated, 5-way speaker binding posts. This allows for five methods of speaker wire termination:
bare wire, Spade lug, pin, single banana and dual banana plug.
Safety Concerns
Use only grounded outlets when powering this product. Making any modification to the power cord could cause unsafe operation and
will void the manufacturer’s warranty.
AC Power Considerations
The A275 requires 3.7 Amps of AC current. When designing any whole house system using multichannel amplifiers, make sure to
provide adequate provisions for all electronic equipment to be installed. This may require additional outlets and/or circuit breakers to
be installed. Consult a licensed electrician in this case.
