CTs 2-CHANNEL SERIES
CTs 2000
Architectural & Engineering Specifi cations
CTs 2000 (120 V, 60 Hz models)
The power amplifi er shall be a solid-state two-channel model employing
Class 1 (BCA) output circuitry.
The amplifi er shall contain protection from shorted, open and mismatched
loads, general overheating, DC, high-frequency overloads, under/over voltage, and internal faults.
If an amplifi er channel starts to overheat, the Thermal Level Control (TLC)
circuit shall engage that channel’s input compressor in an amount proportional to the amount of overheating, in order to generate less heat. If the
channel becomes too hot for safe operation, the channel shall shut off,
and the Thermal Indicator for that channel shall illuminate brightly to alert
the user that a state of thermal stress or overload has caused the channel
to shut down.
The front-panel control shall be a power switch.
Rear-mounted controls shall include Channel Level Controls, High Pass
Filter Switches (one per channel), and a Mode Switch. The High Pass
Filter Switch shall select between fl at and two position of rolloff. The twoposition Mode Switch selects between Dual or Bridge-Mono operation.
The recommended load impedance in Dual mode shall be 2/4/8 ohms and
70V. The load impedance in Bridge-Mono mode shall be 4/8/16 ohms,
140V and 200V. The amplifi er shall be safe when driving any kind of load,
including highly reactive ones.
The rear-mounted output connector shall be one four-pole touch-proof
terminal strip. Rear-mounted input connectors shall be 3-pin balanced
barrier connectors on the standard PIP2-BBY module. This module shall
include a “Y” Input Switch which combines both input signals.
The amplifi er shall be fully compatible with and shall provide appropriate
input cables and connectors for Crown
be fully compatible with Harman Pro System Architect and the Crown IQ
®
System
.
Front panel indicators shall include a yellow Bridge-Mode Indicator that
illuminates when the Mode Switch is set to the “Bridge” position (and
fl ashes if the Mode Switch is changed while the amplifi er is powered
up, indicating that the amplifi er must be powered off and on to reset the
Mode), a green Ready Indicator (one per channel) that illuminates when
the channel is initialized and ready to produce audio output, a green Signal
Indicator (one per channel) that illuminates to indicate the presence of
input signals above –40 dBu, a red Clip Indicator that illuminates when the
THD of the channel’s output signal rises to a level typically considered as
the onset of audible clipping (and illuminates during Thermal Level Control
or input overload), a red Thermal Indicator (one per channel) that illuminates when a state of thermal stress or overload has caused the channel
to shut down (and illuminates in all channels if the power supply goes
into thermal overload), a red Fault Indicator (one per channel) that fl ashes
when a fault condition has occurred in the channel, a yellow Data Indicator
that fl ashes during control data activity (if the amplifi er is equipped with an
IQ-PIP2 module and is connected to a control system), and a blue Power
Indicator that illuminates when the amplifi er has been turned on and AC
power is available (and fl ashes when the amplifi er shuts off due to an
under-/over-voltage condition on the AC mains).

PIP2 modules. The amplifi er shall
The power amplifi er shall meet or exceed the following performance
criteria. Input sensitivity for rated output: 1.4 V. Rated output with both
channels driven in Dual mode with 0.35% THD (20 Hz to 20 kHz): 1000
watts per channel into 2 ohms, 1000 watts per channel into 4 ohms, 1000
watts per channel into 8 ohms, 625 watts per channel into 16 ohms, and
1000 watts per channel (70V or 100V). Rated output in Bridge-Mono mode
with both channels driven at 0.35% THD (20 Hz to 20 kHz): 2000 watts
into 4 ohms, 2000 watts into 8 ohms; 2000 watts into 16 ohms, 2000
watts (140V), and 2000 watts (200V). Frequency Response at 1 watt, 20
Hz to 20 kHz: ±0.25 dB. Signal to Noise Ratio below rated power (20 Hz
to 20 kHz): better than 105 dB A-weighted. Total Harmonic Distortion at
full rated power from 20 Hz to 20 kHz: less than 0.35%. Damping Factor:
greater than 3000 from 10 to 100 Hz. Crosstalk (below rated power, 20 Hz
to 1 kHz): greater than 80 dB. Common Mode Rejection (20 Hz to 1 kHz):
50 dB. DC Output Offset: less than 2 mV. Input Impedance (nominal): 10
kilohms balanced, 5 kilohms unbalanced. Maximum Input Level (before
input compression): + 20 dBu rms. Power Draw at Idle (120 VAC mains, all
channels in 4/8 ohm mode): 35 watts (standby mode).
The amplifi er chassis shall be constructed of steel with a durable black
fi nish and shall be designed for continuously variable-speed forced-air
ventilation from the front panel to the back panel.
The dimensions of the amplifi er shall allow for 19 inch (48.3 cm) EIA
standard (RS-310-B) rack mounting. The amplifi er shall be 3.5 inches
(8.9 cm) tall, and 14.25 inches (36.2 cm) deep behind the rack-mounting
surface.
The amplifi er shall weigh 27 pounds (12.2 kg).
The amplifi er shall be designated the Crown CTs 2000.
