Amplifiers

All measurements were taken on the left channel except as noted. Measured power output results are to the nearest Watt.

The Outlaw Model 7125's frequency response from input to the speaker out measured –0.16dB at 10Hz, -0.04dB at 20Hz, -0.24dB at 20kHz, and -1.11dB at 50kHz.

The S/N (A-weighted, 2.83V into 8Ω from 10Hz-24kHz) measured –114.03dB. Gain measured 28.98dB.

THD+noise at 2.83V into 8Ω measured 0.005% at 20Hz, 0.013% at 1kHz, and 0.004% at 20kHz.

THD+noise at 2.83V into 4Ω measured 0.009% at 20Hz, 0.015% at 1kHz, and 0.007% at 20kHz.

Driving all seven channels into 8Ω, the Outlaw delivered 140Wpc at 20Hz and 142Wpc at 1kHz (to the nearest watt) before clipping (1% THD+noise). The 12-amp main power fuse failed during the 20Hz test and was replaced by a 15-amp fuse (not recommended or necessary for normal operation) for the remainder of the tests. Into 4Ω, all channels driven, the amp clipped at 205Wpc at 20Hz and 225Wpc at 1kHz.

With two channels operating at 1kHz, the Outlaw clipped at 189Wpc into 8Ω and 269Wpc into 4Ω.—TJN
