Meridian Audio G51 - Manual (Page 2)

The two channel amplifier includes the latest
power amp developments from Meridian,
utilised in the flagship DSP8000 digital loud-
speaker systems.
The 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 in-
termodulation distortion, offering superb clarity
and transparency right across the audible range,
with an output impedance that is close to zero
and delivers a solid 100W continuous mean
power per channel into 8Ω suitable for virtually
any high-quality passive loudspeaker system.
The amplifier, when in standby mode, maintains
a standing voltage on the power rails, reducing
the time taken for optimum performance to be
delivered after power-up from tens of minutes
to virtually instantaneous.
Two sets of outputs per channel are provided on
sturdy binding posts colour-coded for easy refer-
ence. The output terminals are connected to the
amplifiers by Van den Hul silver-strand cable to
avoid signal losses.
In addition to the main outputs, a stereo head-
phone socket is provided on the rear panel for
personal listening, A ‘speaker off’ facility is also
included.
