Meridian Product Brochure: Control

In Meridian systems we tend to refer to the controller as the product that supervises the system source and volume level.

In Digital Music Systems the controller could be a DSP loudspeaker or a a CD or DVD Player.

In more complex systems such as Digital Theatre, often the Surround Processor will also be the system controller.

This section describes the controllers used in analogue playback systems that use the more conventional architecture of Preamplifier + Power amplifier.

We also describe the Multimedia controller which can expand the options for a Digital Music System.

502 Analogue Controller

Constructed in dual-mono to match the 557 power amp, the 502 receives balanced inputs and when used with 500 Series amps or M60 active loudspeakers completes a fully balanced analogue system.

502 Controls: Source selection including CD, DAT, Radio, VCR, Video, Cable, Tape and LP; Copy for independent control of the tape output, Display, Mute, Volume and Off.

Inputs: Four unbalanced inputs on phono: 100mV to 4V rms; Three balanced inputs on XLR: 27mV to 840mV.

Outputs: Unbalanced main output on phono: adjustable up to 4V rms. Balanced main output on XLR: adjustable up to 8V rms. Balanced/ unbalanced tape outputs. Balanced-mode volume control with 99 one-dB steps; User-adjustable sensitivity 12dB.
Phono option with new MC or MM plug-in modules for each channel. Large low-field ultra-linear power supply.
