CTs 3000 (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 volt-

age, 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 propor-

tional 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 two-

position Mode Switch selects between Dual or Bridge-Mono operation.

The recommended load impedance in Dual mode shall be 2/4/8 and 70V or

100V. The load impedance in Bridge-Mono mode shall be 4/8/16 ohms and

140V or 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

PIP2 modules. The ampliﬁ er shall

be fully compatible with Harman Pro System Architect or 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 illumi-

nates 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).

CTs 2-CHANNEL SERIES

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): 1500

watts per channel into 2 ohms, 1500 watts per channel into 4 ohms, 1250

watts per channel into 8 ohms, 625 watts per channel into 16 ohms,1500

watts per channel (70V), and 1500 watts per channel (100V). Rated output

in Bridge-Mono mode with both channels driven at 0.35% THD (20 Hz

to 20 kHz): 3000 watts into 4 ohms, 3000 watts into 8 ohms; 2500 watts

into 16 ohms, 3000 watts (100V), and 3000 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. Maxi-

mum 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 27.7 pounds (12.6 kg).

The ampliﬁ er shall be designated the Crown CTs 3000.
