What are the specs for the Audio Research D125?

Power Output:

110 watts per channel minimum continuous power (both channels operating) at 16 ohms from 20Hz to 20kHz with less than .4% total harmonic distortion (typically below .005% at 1 watt) Approximate actual power available per channel at "clipping" (both ch. op., 1kHz): 115 Watts. (Note that the actual power output is dependent upon both line voltage and "condition" ie: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)

Power Bandwidth:

(-3 dB points) 10 Hz to 80kHz

Frequency Response:

-

Input Sensitivity:

0.7V RMS for rated outputs

Input Impedance:

100K ohms, nominal

Output Taps:

4, 8 and 16 ohms

Output Regulation:

Approximately 0.4 dB, 16 ohm load to open circuit

Overall Negative Feedback:

21 dB

Damping Factor:

Approximately 20

Distortion:

Less than 0.4% total harmonic distortion at 110 watts (typically below .005% at 1 watt)

Slew Rate:

20 V/µs

Rise Time:

3 µs

Hum & Noise:

90 dB below rated output - less than 2mV RMS - (Broad-bandwidth unweighted, inputs muted)

Power Supply Energy Storage:

Approximately 280 joules

Power Requirements:

105-125VAC 60Hz (210-250VAC 50Hz) 1000 watts maximum, 400 watts at "idle".

Tube Complement:

(4 matched pairs) 6550

Dimensions:

19" (48 cm) W (standard rack panel) x 8 ¾" (22.2 cm) H x 16½" (42 cm) D (front panel back). Handles extend 1 ⅝" (4.1 cm) forward of the front panel.

Weight:

84 lbs. (38 kg) Net, 95 lbs. (45.5 kg) Shipping
