D1200/D1201
INSTALLATION MANUAL & USER'S GUIDE

INTRODUCTION

The ELAN D1200 Digital Power Amplifier has been designed from the ground up specifically for
custom installers to provide the ultimate solution for multi-room, whole-house applications. Twelve
channels of clean, powerful audio can be combined in dozens of different ways to suit virtually any
situation that may be encountered in whole-house distributed audio systems. The D1200 uses an
audio bus system that allows inputs and outputs to be combined in many ways without the use of
extraneous patch cables. 'Class T' Digital technology and ACE™ (Automatic Clip Eliminator™) allow
efficient use of power, ensuring clean, powerful audio at all volume levels in any application. Remote
triggers and turn-on circuits for each channel enables the installer to integrate this amplifier easily
with any ELAN multi-zone system or in stand-alone applications without additional ELAN equipment.
I. FEATURES
'CLASS T' DESIGN
'Class T' allows the D1200 to deliver its full rated power from all twelve channels simultaneously
and is 90% efficient so the amplifier does not waste energy producing excess heat.
TWELVE HIGH-POWER CHANNELS
Audio quality is greatly improved when plenty of power is applied to each speaker in
a multi-zone environment. Bass sounds better. Dynamic range is improved. Voices sound
full and rich. The D1200 provides 12 x 100 Watts @ 4 Ohms; ideal for virtually any distributed
audio system. ELAN uses an ultra-high efficiency torroidal transformer and 200,000 uF of bulk
storage capacitance to ensure plenty of power when it's needed!
UNIVERSAL STEREO BUS
A-Bus and B-Bus inputs and outputs allow the amplifier to be configured in dozens of different
ways to meet the demands of large audio distribution systems. Channels can be assigned to
one of two audio busses in order to be split or combined according to situational demands.
Audio inputs can be A-BUS, B-BUS, Independent, Stereo, or Mono without the use of extraneous
patch cables. Additional amplifiers can be connected from the Bus outputs of the D1200 to
provide greater system expansion.
ACE™ (AUTOMATIC CLIP ELIMINATOR)
Microprocessor-controlled dynamic leveling circuit eliminates clipping without audio degradation
typical with traditional compressor-based clipping circuits. Each amplified output is continuously
monitored for signal clipping. Extremely fast transients are ignored but if ACE sees a consistent
clipping trend, it turns the respective channel down by one increment. This action is repeated
until no more clipping is detected. Once clipping is absent for five seconds, ACE will slowly and
unnoticeably begin to restore the original gain settings. This translates into accurate high quality
audio reproduction at all volume levels.
