1
Connect analog and/or digital I/O and power to the unit.
The DBMAX will adapt to the power being used in your
area without you having to select a voltage.
2
Turn on the POWER switch at the rear, and press the
POWER key on the front.
3
On LCD IN page 1, select analog, S/PDIF or AES/EBU
Input.
4
Press the REF. LEVELS key and set your I/O
level conditions:
4.1 If you use analog Inputs or Outputs, adjust the analog level
required for digital full scale by selecting a proper value for
the In Level parameter. When a correct In Level is selected,
the red LEDs on the INPUT meter should never light up,
and indication should be in the -18 to -6dB range.
4.2 Your normal operating level, typically the level at which you
would want a calibration tone, may be set as Reference
Level. In a broadcast environment, the Reference Level
would normally be set 18-20dB below your In Level. If you
only want to relate to digital full scale, turn the Reference
Level all the way up.
4.3 The Abs.Peak Output setting determines the maximum
instant peak Output level from the DBMAX. If you work
against digital peak meters or in transmission, the setting
should be spot on. If you work in an environment depending
on analog PPM meters, this setting should be 3-4 dB above
the maximum level allowed with the meter. If you work
against VU meters, the setting should be 12-20dB above the
0VU level.
5. Press the WIZARD key and select the type of limiting/
compression you want by using the PARAMETER keys
and the ADJUST wheel.
QUICK START
6. Press the OK key. Play some program material and leave
the Wizard working while you are playing a soft part and a
loud part of the type of signal the DBMAX will be
processing. 10 seconds of each will do.
7. Press the OK key again, and the DBMAX has loaded a
best fit parameter setting for your application and source
material.
8. If required, go to the COM block in the MAIN PAGE, and
adjust the More/Less setting to suit your taste. Turning the
control to Less makes the unit behave as a Limiter.
Turning the control to More makes the unit behave like a
maximizer.
9. No more overs. Enjoy!
We recommend you read the entire manual before using the DBMAX, but if you’re anxious to get started we suggest
you take the following steps in the described sequence.
