The Mira 3
is a 60 Watt integrated amplifier with full flexibility within the range.
It has a Pre-amplifier output and Power amplifier input. The gain of the
power amplifier is 28dB for full output, and thus enables the amplifier
to be expanded to drive Bi-amplifier or active speaker systems (Sub Bass
etc). It can also drive multiple speakers if required or be part of a
high performance AV system.
The amplifier has
a fully short circuit and DC protected output stage and high quality Evox
film capacitors have been used in the signal path throughout.
The volume level is controlled via a microprocessor, which in turn takes its information from the volume digital encoder on the front panel or remote control handset.
The volume control has a resolution of 1dB per step, giving a total range of 80 steps over the available gain or volume range of 80dB.
There is a calibrated LED display comprising
of 20 LED's, which indicates the gain level or relative position of the
volume control; this is calibrated in 4dB steps, across the total gain
of volume range. The left and right channels are matched and balanced
within 0.2dB, ensuring a centrally placed soundstage no matter what the
volume position or which gain level has been set.
The stepped resistive networks of the volume control are placed in the feedback and input circuits of the ic based line amplifier, thereby optimizing the gain of the line amplifier for a good signal to noise ratio. Also, the stepped resistive network provides the amplifier input with constant input impedance, providing the source component (CD, tuner, tape etc) with a constant impedance load and eliminating the possible changes in sound quality with different volume control positions.
