Crown ct-1600 Manual Suplementario

Unless noted otherwise, all specifications are based

on driving an 8 ohm load per channel, both channels

driven, the sensitivity switch in the 26dB position, the

AC supply is 120VAC at 60Hz. Crown specifications

are guaranteed through the warranty period (normally

3 years). Because our testing methods are more strin-

gent than our published specifications, every Crown

amplifier will exceed its published specifications.

8 Ohm Stereo—110W/Ch

4 Ohm Stereo—150W/Ch

70-V Line Stereo—105W/Ch

8 Ohm Bridge Mono—295W

4 Ohm Parallel Mono—225W

2 Ohm Parallel Mono—300W

Bridge Mono, 140-V Line—210W

Parallel Mono, 70-V Line—210W

Load Impedances: Rated for 16, 8, 4, 2, Ohm, and 70-V

use. Safe with all types of loads, even totally reactive

loads.

AC Mains: 120VAC at 60 Hz with standard three-wire

grounded connector for North American units; 100VAC,

120VAC, 220VAC, and 240VAC at 50 or 60 Hz units are

available when ordered country specific. Com-Tech

amplifiers are not voltage convertable.

Frequency Response: ±0.1dB from 20 Hz to 20 kHz at 1

Watt.

Phase Response: ±10° from 10 Hz to 20 kHz at 1 Watt.

Signal to Noise Ratio: A-weighted, better than 105 dB

below full rated output. Better than 100 dB below full

rated output from 20 Hz to 20 kHz.

Total Harmonic Distortion (THD): <0.05% from 20 Hz to

1 kHz, increasing linearly to 0.1% at 20 kHz at 500W.

I.M. Distortion: <0.05% from less than 164 milliwatts to

520 W at 26 dB gain.

Slew Rate: >13V per microsecond. (Slew rates are

limited to useful levels for ultrasonic/RF protection.)

Damping Factor: >1000 from 10 Hz to 400 Hz.

DC Offset: <10 millivolts.

Input Impedance: Nominally 20K ohms balanced; 10K

ohms unbalanced.

Output Impedance: <10 milliohms in series with <2

microhenries.

Protection Systems: Output Device Emulation Protec-

tion (ODEP) limits drive in the event of dangerous

dynamic thermal conditions without interrupting power.

Current limiting for shorted load protection. DC/LF and

common mode output current Fault circuitry to mute

audio. Delay of 4 seconds from turn on mutes amplifier

to prevent dangerous turn-on transients.

Input Connectors: Balanced three-terminal barrier block

for each channel on standard P.I.P.-BB module (in-

cluded)

Output Connectors: Four-terminal barrier block.

Front Panel Controls: A front panel rocker switch used to

power the amplifier on and off.

Back Panel Controls: A three-position switch which se-

lects  Stereo, Bridge-Mono, or Parallel-Mono mode. A

rotary potentiometer for each channel used to control

output level. A two position recessed switch for each

channel selects between 8/4 ohm and 70-V modes. A

push button circuit breaker used to protect the power

supply.

Internal Controls: A three-position switch selects 0.775V,

1.4V, or 26 dB voltage gain input sensitivity.

Indicators: Amber Enable indicator shows on/off status

of low-voltage power supply. A green indicator for

each channel shows the reserve energy status. If no

reserve energy is available the indicator will dim in

proportion to ODEP limiting. A yellow indicator for each

channel flashes in the event of distortion. And green

SPI (signal presence indicator) indicators show the

presence of output signal.

Construction:  Black splatter-coat steel chassis with

specially designed flow-through ventilation system.

Mounting: Standard EIA 310 front-panel rack mount

with supports for supplemental rear corner mounting.

Dimensions: 19 inches wide, 3.5 inches high, 16 inches

deep behind front mounting surface.

Weight: 29 lbs, 6.5 oz.
