Crown ct-1600 Manual Suplementario

Spec: 

≥

 100 dB below 8 ohm rated continuous average

20-20kHz power.
Initial Conditions: Controls per standard. Short inputs.

Procedure: Load each channel to 8 ohms. Measure less

than 290µV at the output of each channel (20 Hz-20
kHz bandpass filter).

Spec: < 80mV across an 8 ohm speaker load

Initial Conditions: Controls per standard.

Procedure: Load the output with an 8 ohm speaker.

From an on condition, turn off the amplifier and monitor
the output noise at the time of turn off.
Note: Turn off noise may increase significantly if the

amplifier is cycled off and on.

Spec at 0 dB output: 

≤

 0.01%.

Spec at -35 dB output: 

≤

 0.05%.

Initial Conditions: Controls per standard.

Procedure: Load each channel to 8 ohms. Inject a

SMPTE standard IM signal (60 Hz and 7 kHz sine wave
mixed at 4:1 ratio). Set the 60 Hz portion of the sine
wave to 23 volts RMS. Set the 7 kHz portion to 25%.
With an IM analyzer measure less than 0.01% IMD.
Repeat test at -35 dB (reference 23 volts RMS, 60 Hz
portion) and measure less than 0.05% IMD.

Spec: No protective action during test.

Initial Conditions: Controls per standard.

Procedure: Load each channel to 8 ohms. Inject a 1 kHz

sine wave into each input and drive the output 6 dB into
clip for 10 seconds. The amplifier should not activate
any protective circuits (ODEP, Fault, or LF Protection).

After completion of testing, if all tests are satisfactory,
the amplifier controls should be returned to the posi-
tions required by customer. If conditions are unknown
or unspecified, factory settings are as follows:
Level Controls: 9 to 11 O'Clock.

Sensitivity Switch: 0.775V 8/4 Ohm.

Stereo/Mono Switch: Stereo.

70-V Mode Switches: 8/4 Ohm position.

Power: Off
