that a single

for both hybrids, with

each hybrid's output fed to the other's input

Both hybrid

still

function independently.

The internal

sums

the user-provided

inputs. The user

must have

NO hybrid

located

on the connector board, marked

all

five jumpers from the

position to the

hybrid input. The input to the

hybrid is disabled. Both input

front panel function normally. The

fixed

unity

relying

on the
