Specification
Rated Output Power
8 Ω Stereo
80 watts (19.03 dBW) minimum per channel from 1 ~ 20,000 Hz at 0.05% THD or less.
90 WPC (19.54 dBW) in Crown's manual at 1 kHz at 0.1% THD.
Crown elsewhere refers to rated power as 75 WPC (18.75 dBW), especially where it refers to sensitivity.
4 Ω Stereo
125 watts (20.97 dBW) minimum from 1 ~ 20,000 Hz at 0.05% THD.
145 to 155 WPC (21.61 ~ 21.90 dBW) at 1 kHz at 0.1% THD.
8 Ω Mono
315 watts (24.98 dBW) at 1 kHz at 0.1% THD.
16 Ω Mono
160 watts (22.04 dBW) minimum from 1 ~ 20,000 Hz at 0.05% THD.
180 watts at 1 kHz at 0.1% THD.
Output Loads
4Ω, 8Ω and 16Ω.
Safe with any load, including shorts — open circuits and reactive loads — although it will kick-in its protection circuitry with 2Ω loads.
Input
Two mono ¼" unbalanced phone jacks, 25 kΩ ± 30%.
The inputs feed 25 kΩ potentiometers directly, whose outputs feeds the amplifier.
Input Sensitivity
1.19 V ± 2% for rated power into 8Ω.
Since its gain is 20.6x (26.28 dB), 1.19 V in gives us 24.514 V out, or 75 watts for rated power.
There's an internal jumper to increase the gain to 0.775 V sensitivity.
Frequency Response
DC ~ 20,000 Hz ± 0.1 dB at 1 watt.
DC ~ 100,000 Hz ± 1 dB at 1 watt.
Size
3 RU, 8" deep measured.
5.25 x 19 x 8.75" HWD, depth is behind mounting flange.
133 x 483 x 222 millimeters HWD, depth is behind mounting flange.
Weight
24 lbs. (10.9 kg).
