BLOCK DIAGRAM
18
This is a roughblock diagram of the Wave with a little liberty taken for the sake of clarity.
The input selector consists of a number of discrete relays and is not a rotary switch but acts
like one except with less L/R crosstalk. Also this is fully balanced so both halves of the
signal are switched.
The Insert block shows amplifiers needed for balanced to unbalanced conversion when the
insert is unbalanced and uses RCA connectors. The balanced option eliminates those
amps because they are not needed for short cable runs.
The circles represent input and output jacks and don't really show balanced and
unbalanced lines. The Mute Switch is not in-line and just shorts the output to ground for
muting. Output 2&3 when off also short to ground for silence.
The 4 deck motorized volume pot is shown on the Analog Board but it lives on its own
board along with the motor driver.
Except for the main cable between the Power Supply and the Analog Board, no attempt
was made to show power supply lines, however the location of some of the important
regulators is shown. There are 6 more 5V regs on the DAC board which are fed pre-
regulated 8V from the power supply.
