Overview
The Reference 110 redefines expectations and value in a truly state-of-the-art stereo amplifier. It is perfect for anyone who does not require the high power provided by our larger monoblock Reference amplifiers.
The dimensions of the REF110's chassis are identical to those of a REF210, large but not unwieldy. The thick front panel simply has an On/Off switch and corresponding LED and does not contain the vacuum-fluorescent display found on its more powerful siblings.
The attractive internal layout is similar in appearance to the REF210 with the right and left channel boards mounted horizontally, flanking the transformers mounted on a raised central channel running front-to-back. A small LCD display indicating tube hours is mounted on the front of the right channel board and is visible through the top. Two small 12V D.C. fans are mounted on the rear panel, with a small internal switch allowing their speed to be set to low, medium or high. Input is balanced XLR only, while the output has separate taps for 4-8-16 ohm speaker loads via our proprietary five-way binding-posts. The REF110 has two 12V triggers (input and output) to allow remote turn-on, and there is a 20A IEC connector for the power cord.
Specification

POWER OUTPUT: 110 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.3% at 110 watts, below 0.03% at 1 watt. |
|
Approximate actual power available at "clipping" 120 watts (1kHz). (Note that actual power output is dependent upon both line voltage and "condition" i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.) |
|
FREQUENCY RESPONSE: |
|
( -3dB at 1 watt) 0.6Hz to 90kHz. |
|
INPUT SENSITIVITY: 1.8V RMS BAL for rated output. (24dB Bal gain into 8 ohms.) |
|
INPUT IMPEDANCE: 300K ohms Balanced. |
|
OUTPUT POLARITY: Non-inverting. Balanced input pin 2+ (IEC-268). |
|
OUTPUT TAPS: 16 ohms, 8 ohms, 4 ohms. |

|
HUM & NOISE: Less than 0.2mV RMS |
|
-106dB below rated output (IHF weighted, input shorted). |
|
POWER SUPPLY ENERGY STORAGE: Approximately 520 joules. |
|
POWER REQUIREMENTS: 105-125VAC 60Hz (210-250VAC 50 Hz) 630 watts at rated output, 800 watts maximum, 410 watts at "idle." |
