o Two as yet undefined future functions, F1 and F2
o Hush (about 14 dB cut) and MONO options
Options for balanced outputs (not yet available)
Volume control has precise tracking over the widest possible range.
Front panel 1/8” input for Ipod
Microcontroller version is reported by flashes of the F1 LED at power-up. The
form for version 1p4 is (the quick flashes delimit the ends of the slow flash
sequence that specifies the version):
o 2 quick flashes, 1 slow flash, 4 slow flashes, 2 quick flashes
IEC power connector
120- or 240-volt operation (with wiring strapping change)
Gain Customization
Speakers and amplifiers have a wide range of sensitivity. This might leave the volume
control crowded towards the low end for your normal listening levels. Should this be the
case, you can reduce the gain of the preamp by about 6 dB if you remove R3 and R5 from
the tone volume board. If the preamp is already built, the easiest way to do this is just to
clip the two resistors off the tone volume board. This should put the normal listening
position of the volume control further clockwise in its rotation.
