SuperNova 2
switching the current source to one of the front ends. The outputs of the front ends
are summed into the back-end circuitry. In this way no switching occurs in the signal
path when not using the switched attenuator.
The SuperNova is fully dual mono and is powered from a remote dual mono power
supply. The remote power supply supports NiMH rechargeable batteries but is
designed to work perfectly without the batteries. The batteries will allow the
SuperNova to run completely isolated from the wall power for a period of three
hours. There are four independent charging circuits for the four battery packs. The
SuperNova has an 11-position switched attenuator output that allows "direct output"
to a power amplifier.

Required Attenuation -30dB
Most Audio systems have far too much gain. The excess needs to be reduced by
setting an attenuator by a typical -30dB. By reducing unneeded gain, the system
does not need to work as hard, thereby achieving a more natural sound. The extra
25dB gain equates to about 20 times more work. Imagine working 20 times harder
than you need to?
The limited attenuator has a major advantage over a passive attenuator. A passive
attenuator typically has significant output impedance creating sensitivity to the
particular type of output cable. The limited attenuator has much lower output
impedance.
