RTS Systems Model 405

Phono Pre-Amplifier

RTS Systems Model 405


The model 405 is a high performance two-channel phono pre-amplifier designed for use in professional applications.

It features adjustable cartridge termination, switchable rumble filter, two sets of selectable level controls and a choice of two output formats.

The design is based on a clear understanding of the most important factors in accurate phono reproduction.

The 405 is a transparent preamplifier, free of colouration, distortion or interference and can be used with confidence as a reference playback system preamp.

If the remainder of the system is clean, accuracy of reproduction now rests with the cartridge, tonearm and turntable.
