Soulution Audio 501 Mono Amplifier

Quick Overview

Soulution Audio 501 Monoblock Amplifier

The amplification circuit of the 501 is based on the technology of the 710 and 700 amplifiers. At its core is a proprietary voltage amplification stage that consists of linearized amplifiers operating up to a cutoff frequency of 80MHz.

Current amplification is done in three stages, each using a very small and thus almost linear operating range. The high Class A operation supplemented by 47,000µF of storage capacitance results in a nearly infinite impulse response. Massive copper bars on the amplifier board and to the speaker terminals ensure that all the power of the 501 mono amplifier is available to drive the speaker.

High-precision idle current management ensures optimal Class A operation for all conditions, without requiring any readjustment in the music signal. Optimal sound is thereby guaranteed immediately from switch on. Control circuits that protect against RF or DC signals at the input, and short circuits at the output ensure safe operation in all situations. The input level is also monitored continuously.
