Summary Specifications
Frequency Response (at 1 watt, 20 Hz - 20
kHz): ±0.25dB.
Signal to Noise Ratio below rated full-band-
width power, A-weighted: > 112 dB.
Total Harmonic Distortion (THD) at full rated
power: < 0.1%.
Intermodulation Distortion (IMD) 60 Hz and
7 kHz at 4:1, from full rated output to –35 dB:
< 0.2%.
Damping Factor (20 Hz to 100 Hz at 8 ohms):
> 5000.
Crosstalk (below rated power, 20 Hz to 1 kHz):
> 80 dB.
Common Mode Rejection (CMR) (20 Hz to 1
kHz): > 70 dB typical.
Latency (analog, digital inputs): 1.13 mS analog,
1.81 mS digital (96 kHz).
A/D, D/A Converters: 24-bit 192 kHz Cirrus
Logic.
Digital Input: AES/EBU, 24-bit, 32-96 kHz.
Onboard sample-rate converter.
Network: Onboard TCP/IQ and HiQnet, compat-
ible with standard 100 Mb Ethernet hardware.
DSP: 24-bit conversion with 32-bit, floating-
point DSP processing. World-class IIR and
linear phase FIR filters. Has 64 assignable filters
with 9 different filter types. Includes all-pass
filters, over 2 seconds of delay available per
channel, and dual uncorrelated-noise and sine-
wave generators.
Load Impedance: (Note: Safe with all types of
loads) Stereo: 1/2/4/8/16 ohms. Bridge Mono:
2/4/8 ohms.
Input Sensitivity (referenced to 8 ohm rated
output): Adjustable in 0.1V steps from 1.4V to
7.75V.
Required AC Mains: Universal AC input, 100-
240VAC, 50/60 Hz (±15%). Maximum AC mains
voltage 277VAC.
AC Line Connector: Five cordsets supplied with
amplifier (USA, UK, European, Australia, India).
Front Panel Indicators, Controls and
Connectors
Indicators: Bridge mode, Ready, Signal level,
Clip, Thermal error, Fault, Network data, Power,
AC mains.
LCD Control Screen and Controls: These let
the user adjust the amplifier’s attenuation and
muting, configure the amp, set up and view
error monitoring (such as temperature and load
supervision), set IP and HiQnet addresses from
the front panel, and recall DSP presets. The
presets allow the user to quickly reconfigure the
amp for various applications.
Level Controls (Encoders): Speed-sensitive
rotary encoders, 0.5 dB steps, range 0 to –100
dB. These two knobs affect the Channel-1 and
Channel-2 output levels. They also select Menu
items and adjust parameter values that are
displayed on the LCD Control Screen.
Power Switch: Push-on/push-off switch with
built-in green AC mains present indicator.
USB 2.0 Connector: Accepts a USB drive to
transfer presets from the drive to the amplifier
DSP, and vice versa.
Back Panel Connectors, Controls,
and Indicators
Connectors: Balanced XLR analog inputs, bal-
anced analog XLR loop-thru outputs, AES/EBU
digital input, AES/EBU digital loop-thru output,
4-Pole Speakon output connectors, binding
post output connectors, power cord, EtherCon
®
Ethernet connector for networking via HiQnet or
CobraNet.
Reset Switch/Circuit Breaker: If the current
draw of the amplifier exceeds safe limits, this
breaker automatically disconnects the power
supply from the AC mains. The switch resets the
circuit breaker.
Preset Indicator: LED flashes to signal the
number of the current preset if active. LED is
green if the preset values have not been changed
once loaded. LED is yellow if the preset values
have been changed since they were loaded.
