1) Clean and De-mag machine

2) set in SAFE mode. Use Test Tape or Client's Tone Tape

3) set REPRO LEVEL

4) set SYNC LEVEL

5) set REPRO High Freq EQ

6) set SYNC High Freq EQ (if machine has it)

7) "rough" set REPRO Low Freq EQ (if using a Test Tape) or if using a Client's tone tape, set Low Freq EQ corectly

8) set SYNC Low Freq EQ as above

9) remove Test tape or client's tone tape

===========

if BIAS is correctly set... continue to #10.      If not go to step #19

10) send "0VU 1khz tone" to machine

11) use correct blank type tape (499, 456 ect..)

12) go into RECORD, monitor REPRO

13) set RECORD LEVEL (Studers: must set INPUT LEVEL before RECORD LEVEL)

14) send "10khz 0 VU tone"

15) set RECORD High Freq EQ

16) send low freq tone at 0 VU (50hz for 15ips, 100 hz for 30ips..)

17) set REPRO Low Freq EQ (there is no record low freq eq...)

18) put machine in INPUT. Set INPUT LEVEL (not STUDERS..)

=========

BIAS

19) use correct type blank tape.

20) send 10khz 0vu tone

21) Begin recording, monitor REPRO

22) turn BIAS control COUNTER-CLOCKWISE until VU meter drops PAST peak

23) now turn CLOCKWISE to peak VU meter reading. note this peak level.

24) now continue CLOCKWISE (more bias) until the VU meter peak reading DROPS 3 1/2 db PAST the peak level (15 ips) or 2 db (30 ips)

25) Each type of tape has it's "best bias" point. 3 1/2 is a guideline for 15 ips operation. For 30 ips, using 10 khz, use 2 db overbias as a guide..
