CONTRACTOR SERIES
L
ooking for a quality, constant voltage and low
impedance two channel amplifi er for your res-
taurant, nightclub, retail store, school or house
of worship projects? The Crown
®
“Contractor Series”
amplifi ers are designed just for you.
CH-Series amplifi ers can directly drive “constant
voltage” lines, so you can avoid the expense of
adding step-up transformers for distributed loud-
speaker systems.
All Contractor-Series amplifi ers feature Crown’s
exclusive SST (System Solutions Topologies) expan-
sion system. The SST expansion system makes it
easy to tailor your amplifi er to a specifi c application
or to add future technology as it develops.
With an incredibly wide range of power and fea-
ture/benefi ts, Contractor-Series amplifi ers give the
professional sound contractor more options. Crown
quality is available at the best dollar-per-watt ratio on
the market.
For more details about the Crown Contractor Series,
contact the Crown Technical Support Group at 800-
342-6939 or 574-294-8200. Also, visit the Crown
Audio website at www.crownaudio.com.
Specifi cations
Note: All measurements apply to amplifi ers in stereo
mode with 8 ohm loads and an input sensitivity of 26
dB gain, 1 kHz at rated power unless other otherwise
specifi ed. Specifi cations for units supplied outside
the U.S.A. may vary slightly at different AC voltages
and frequencies.
Power
Output Power: See power charts below.
Load Impedance:
Safe with all types of loads.
4 and 8 ohm Stereo.
16 ohm (CH1) or 8 ohm (CH2) or 4 ohm (CH4) at
70V Stereo.
4, 8 and 16 ohm Bridge.
32 ohm (CH1) or 16 ohm (CH2) or 8 ohm (CH4) at
140V Bridge.
64 ohm (CH1) or 32 ohm (CH2) at 200V Bridge.
Voltage Gain, 1 kHz, 1.4V sensitivity:
30.5 dB (CH1) or 32.1 dB (CH2) or 34 dB (CH4)
at 8 ohms.
34 dB (CH1) or 34 dB (CH2) or 34 dB (CH4) at
70V.
AC Line Requirements:
Note: North American units are 60 Hz only. All other
models are 50/60 Hz. Voltages are ±10%.
AC Line Current:
100V: 7.6A (CH1) or 11.4A (CH2) or 8.5A (CH4).
120V: 6.3A (CH1) or 9.5A (CH2) or 7.1A (CH4).
230-240V: 3.5A (CH1) or 5.0A (CH2) or
3.7A (CH4).
AC Line Connector: Detachable 15A IEC connector
with country-specifi c plug.
Performance
Frequency Response, 20 Hz to 20 kHz at 1 watt: ±0.1
dB (CH1, CH2) or ±0.25 dB (CH4).
Phase Response: ±15 degrees deviation from linear
phase from 20 Hz to 20 kHz at 1 watt.
Signal to Noise Ratio, A-Weighted: Better than 105
dB (CH1, CH2) or 102 dB (CH4) below rated 1-kHz
power.
Total Harmonic Distortion (THD), 1 kHz at rated
power: 0.5% or less true THD from 20 Hz to 20 kHz.
Intermodulation Distortion (60 Hz and 7 kHz at 4:1):
Less than 0.1% (CH1, CH2) or 0.5% (CH4) at rated
power to 30 dB below rated power at 8 ohms.
Damping Factor (8 ohm): Better than 400 (CH1, CH2)
or 700 (CH4) from 10 Hz to 400 Hz.
Crosstalk, 20 Hz to 20 kHz: Better than 50 dB below
rated power.
Common Mode Rejection (CMR): Better than 40 dB
from 20 Hz to 1 kHz.
DC Output Offset (shorted Input): < ±10 mV.
Features
Drives multiple impedances, with both low
impedance and high impedance outputs per
channel.
High-pass filter for each channel provides
low-frequency roll off to eliminate step down
transformer saturation when used in 70V dis-
tributed systems.
Shallow chassis design, allowing for installa-
tion in most wall-mount racks.
Rear panel detented level controls allow for
accurate level settings and secure operation.
“Contractor-Correct” barrier strip output con-
nectors allow for quick and easy connection,
regardless of the load.
Advanced protection circuitry guards against:
shorted outputs, open circuits, DC, mismatched
loads, general overheating, high-frequency
overloads and internal faults.
Can be mounted in standard (19-inch (48.3-
cm)) rack, shallow (14-inch (35.56-cm)) rack,
or stacked on top of each other.
Accurate, uncolored sound with very low
distortion for the best in music and voice repro-
duction.
Three-Year, No-Fault, Fully Transferable War-
ranty completely protects your investment and
guarantees its specifi cations.
• Crown’s Profi t Protection Plan guarantees quick,
no-questions-asked replacement of your covered
Contractor Series amplifi er should it fail at any
time up to 6 months following date of installation.
