Marantz 2440

Description

The Marantz model 2440 quadradial adaptor amplifier converts any stereo system with tape source monitor feature to a full featured 4-channel system.

The 2440 incorporates Marantz's exclusive vari-matrix circuit which simulates 4-channel sound from normal 2-channel stereo programs, and is capable of reproducing 4-channel sound from any matrix encoded source.

It will also reproduce any discrete 4-channel program as well as regular stereo and monaural programs.

An optional plug-in decoder adapts the 2440 for specific matrix systems such as Columbia's SQ or Electro-Voice Stereo 4.

I have had this unit since it was new, matched with my Marantz 2226-B reciever, works great to this day and sounds great pumped through my (2) M-400t Carver cube's, and Bose speakers, the only thing i dont care for is the balance (slider) controls.
