Specifications
| Frequency response | High level sections: ±.25 dB 20 Hz to 20 kHz. -3 dB
points, 1 Hz and 100 kHz Magnetic phono: ±.5 dB of RIAA, 20 Hz to 20 kHz Optional moving coil pre-preamp (MCP-1) -3 dB points, 1 Hz and 100 kHz |
|---|---|
| Distortion (THD) | Harmonic distortion: Less than 0.005% at 2 V RMS output (IHF
load) Intermodulation distortion: Less than 0.005% at 2 V RMS output (IHF load, SMPTE method) THD and IMD decreases with decreasing output |
| Noise & hum | High level inputs, more than 90 dB below 2 V RMS output. Magnetic phono input, less than 1 µV equivalent input noise with 1 Kohms input (RIAA weighted). Typically 80 dB below 10 mV input at 1 kHz. |
| Gain | Magnetic phono input to tape output, 36 dB. Magnetic phono input to main output, 60 dB. High level inputs to main output, 24 dB. |
| Input impedance | 50 Kohms (nominal, all inputs) Magnetic phono 50 Kohms 200 pF (capacitance value may be reduced to 50 pF minimum, or increased as necessary). |
| Output impedance | 50 ohms, recommended minimum load for maximum audio quality, 10 Kohms. |
| Output polarity | |
| Maximum inputs | High level inputs, esentially overload proof. Magnetic phono input, 150 mV RMS @ 1 kHz. |
| Rated outputs | Maximum output 10 V RMS (all outputs, IHF load). |
| Power supplies | |
| Power requirements | 105-120/210-240 VAC, 50/60 Hz, 20 watts |
| Other | |
| Dimensions | 19" (48 cm) W (standard rack mount front panel size) x 3 ½" (8.9 cm) H x 8 ½" (21 cm) D. Handles extend 1 ½" (3.8 cm) forward of panel. Rear chassis fittings extend ¾" (1.9 cm). |
