CHAPTER 1

Introduction

Dear Friend,

Thank you for pur chas ing my
SunÞ re Symphonic Reference
AmpliÞ er. I hope that you enjoy it and
the music it makes as much as I have
en joyed creating it for you.

Unpacking

Your SunÞ re AmpliÞ er should
reach you in perfect con di tion. If
you do notice any shipping damage,

User's Manual

Overview

Your SunÞ re Symphonic Refer-
ence AmpliÞ er is actually two high-
powered ampliÞ ers combined in
a 17 inch wide chassis. It accepts
line-level signals from a controlling
preampliÞ er, and ampliÞ es them to
a higher speaker-level, suitable for
driving powerful stereo and Home
Theater speak ers.

Rear Panel Features

CHAPTER 1

1. AUTO/ON/OFF Switch

Your SunÞ re AmpliÞ er is designed
with an automatic on/off circuit.

• In the AUTO-ON (center)
po si tion, the am pli Þ er will au-
tomatically turn on if an audio
signal is present at the left
or right input, or if it receives
an input trigger voltage at the
12 VDC inputs. The ampliÞ er
will automatically turn off after
a few seconds if the trigger
voltage is removed, or after ap­ prox i mate ly 20 minutes in the
ab sence of an audio signal.

User's Manual

• In the ALWAYS-ON (up) posi­tion, the ampliÞ er is always on,
regardless of input signals or
12 VDC trigger.

• In the ALWAYS-OFF (down)
position, the ampliÞ er is always
off, regardless of input signals
or 12 VDC trigger.

2. 12 VDC Trigger Input

Although the signal sensing turn­on is ad e quate for most installations,
the 12 VDC trigger inputs are offered
as an op tion al way to turn on the
ampliÞ er.

The SunÞ re Symphonic Refer-
ence PreampliÞ er has a com pat i ble 12
VDC trigger output. When the pream­pliÞ er is turned on, the ampliÞ er will
also turn on.

1/8" mono mini jacks are provided
for ease of installation, along with a
terminal strip to allow more ß exibility
for custom-wired installations. The
terminal strip and both the 1/8" mini
jacks are connected in parallel, allow­ing 'daisy chaining' to turn on multiple
ampliÞ ers.
