Input sensitivity and pre-amp gain

The

Mira 3

amplifier sensitivity or pre-amplifier gain can be set to

three different levels; this is performed by putting the amplifier in to
a programming mode on turning on the amplifier.
Please note the amplifier is set to normal sensitivity (level 2) in the
factory, this setting being suitable for all normal Hi-fi requirements.

Settings -

Sensitivity's for 61W into 8 Ohms

CD, tuner, Line 1, line 2, Tape input sensitivity
Gain range or level 1 sensitivity = 870mV
Gain range or level 2 sensitivity = 220mV (Factory setting)
Gain range or level 3 sensitivity = 150mV

Phono input sensitivity

Gain range or level 1 sensitivity = 8.5mV
Gain range or level 2 sensitivity = 2.1mV (Factory setting)
Gain range or level 3 sensitivity = 1.4mV

Pre-amplifier gain levels to pre-amplifier output.

Gain range or level 1 gain = 0dB (unity gain)
Gain range or level 2 gain = 11.5dB (factory setting)
Gain range or level 3 gain = 15dB

Any adjustments made to the power amp link switch and gain must
be carried out by an authorised Rega dealer.

If work is carried out by any person other than a Rega dealer it will
invalidate your warranty.
