Meridian G02 Balanced Dual Mono Control Unit
Meridian has a strong reputation for preamps, and the G02s predecessor, the 502, was no exception. Building on the success of the 502, the Meridian G02 is a true dual-mono analogue control unit/preamplifier with an extremely high-quality power supply for ultra-low noise and distortion. Featuring a fully-balanced signal path throughout, it is an ideal complement for the G Series power amplifiers and is particularly suited to those who wish to maintain a balanced, analogue signal path at the very highest quality of reproduction.
Although Meridian is today best-known for its digital circuitry, it is a company built on analogue roots, and indeed, superb analogue circuit design and implementation are important parts of all Meridian products, whether their inputs and outputs are analogue or digital.
Balanced operation has always been preferred in the professional audio industry, as it can significantly reduce hum and noise and make the system immune to interference. The G02 brings this philosophy to the G Series.
Including both a preamplifier and controller, the G02 dual-mono control unit provides no less than seven two-channel analogue inputs. Four of these ñ nominally designated Aux, Radio, TV and VCR (though these designations can be changed) ñ are unbalanced; while the remaining three ñ CD, Tape and Disc ñ offer balanced inputs on XLR connectors.
The internal architecture of the G02 is balanced throughout, and the first thing that happens to an unbalanced input is that it is electronically balanced for maximum quality throughout the signal chain.
The front-panel volume knob (press to mute) activates a specially-designed dual differentially-balanced volume control circuit. This ensures perfect stereo tracking and full frequency range performance at all volume levels.
The disc (turntable) input can be specified for either moving coil or moving magnet cartridge operation with the addition of appropriate factory-fitted phono modules. The sensitivity of each input can be individually adjusted as desired.
Two sets of unbalanced stereo tape outputs are included on the rear panel, allowing maximum flexibility in the configuration of tape/decoder loops and multi-room capabilities. The outputs can be configured as a single balanced output with a suitable break-out cable.
Two sets of main outputs are provided: the primary outputs are balanced on XLR Male connectors, while auxiliary unbalanced outputs are also included on phono connectors. All audio interface connectors are gold plated for maximum transparency.
System setup in the G02 can be configured via the serial link, which can also be used for remote control applications. The G02 control unit forms the perfect heart of a high-quality balanced analogue stereo system.
