The Story

Pioneer Spec-1

Rack Mount Stereo Pre-Amplifier (1976-80)

Description

The Spec-1 has differential amplifier circuitry incorporated in the equalization and tone control amplifiers.

This is complemented by a dual positive and negative power supply system for all amplifier sections, which provides improved DC balance and stability, while eliminating click noises due to switching.

An electronic muting circuit, employing a reed relay, blocks surge noise associated with power switch operation.
