Crown audio performs better for you. Now with the ITECH HD series of amplifiers, Crown is innovative, quality, and performance. The ITECH HD series is definitely the way to go.
Frequency Response (at 1 watt, 20 Hz - 20
Signal to Noise Ratio below rated full-bandwidth
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:
Damping Factor (20 Hz to 100 Hz at 8 ohms):

> 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,
compatible with standard 100 Mb Ethernet
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:
Input Sensitivity (referenced to 8 ohm rated
output): Adjustable in 0.1V steps from 1.4V to
Required AC Mains: Universal AC input,
100-240VAC, 50/60 Hz (10%). Maximum AC
mains voltage 264VAC.
AC Line Connector: Five cordsets supplied with
amplifier (USA, UK, European, Australia, India).
Front Panel Indicators, Controls
Indicators: Bridge mode, Ready, Signal level,
Clip, Thermal error, Fault, Network data, Power,
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,
Connectors: Balanced XLR analog inputs,
balanced 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
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
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.
