Eac h of the four (4) PGM VU meters can be

the PG M busses or the TAPE RTN's. Whe n the

Select Switch
Whe n pressed, this switch connects the specific
TAPE R ET U R N to the corresponding TAP E
MONITOR section, a llows access of the re tur n­
ing signal to the M E T E R , and provides signal to
a specific AUX SEND control. If the returning
signal is not chosen, the switch re places the
TAPE signal with that of the PROG RAM. Thus,
the MON ITOR and A U X sends can re ceive and
process signals from e i ther of the TAPE R E­
T U R NS or the PROG RAM.

AUX 3,AUX 4 Send Controls (M-312&M-320

Each MON I TO R se ction contains one of these
controls. AUX 3 is accessed from TAPE R E­
T U R N S 1-4, while AUX 4 deri v es signals from
TAPE RETU RNS 5-8. Since the AUX 3 & 4
rece ive the ir signals after, or post, the TAPE
RTN Switch (see the prev ious description), the
setting of this switch dete rm i ne s the signal
processed by the AUX SENDS.

Once the signal sou rce has bee n dete rmined and
