amplifiers feature active bias control throughout, with thermal sensing that carefully manages the temperature and current flow at different volume levels.

Fully DC-coupled, the signal path contains no capacitors, while those in the power supplies are audiophile grade components.

The amplifiers are of a unique low-feedback design for minimum transient and interface dis- tortion, offering superb clarity and transparency right across the audible range, with an output impedance that is close to zero and suitable for virtually any high-quality third-party passive loudspeaker system.

Trigger capability allows the G56 to be switched on remotely by means of a signal from your pre- amp. Trigger and other control signals are opti- cally isolated from the amplifier itself. When in stand-by mode, a standing voltage is maintained on the power rails and supply components. As a result, you do not have to wait for half an hour after switching on for optimum performance to be achieved: it is there immediately.

Two sets of outputs are provided per chan- nel for bi-wiring, etc, on sturdy binding posts colour-coded for easy reference and capable of handling large-diameter high-quality loudspeak- er cables. The output terminals are connected to

the amplifiers by Van den Hul silver-strand cable to avoid signal losses.

The amplifier can be operated in bridge mode by actuating a switch on the rear panel, in which case the left channel input becomes the input for the bridged pair and the inner output terminals are bridged, power being derived from the outer terminal pairs (see rear panel diagram).

The amplifiers include electronic protection reset by power-cycling, with full DC and thermal protection.

A front-panel indicator shows when the ampli- fier is in standby. When the unit is activated, an LED illuminates for each channel. In the event of thermal overload, the main indicator goes red and the channel lights go out, showing that the unit is off-line. A pushbutton on the front panel can be used to take the unit in and out of stand- by, while flexible 5–30V AC/DC trigger capability allows amplifier power to be controlled remotely along with the rest of a system.
