100w Stereo amplifer
The Quad 520 is a two channel 100 to 150 watt amplifier for 19 inch 2U rack mounting.

Intended to drive loudspeaker loads the amplifier will deliver up to 100 watts into 8 ohm or 150 watts into 4 ohm with very low distortion.

Input sensitivity is 0.5 Vrms for full output with a lockable gain control.

Balance inputs can be provided to special order.

The standard of quality of the amplifier is of the highest order, and with any complex input distortion falling within the useful part of the audio range will not exceed a small fraction of one percent.

Overloading with any load will not significantly affect long time constants, ensuring immediate recovery and minimum distortion resulting from such overload.
