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.

DBMAX SETUP
The DBMAX is carefully designed to optimize or limit the overall level and enhance the energy in your material.
The use of the five band Compressor, Limiter and Expander makes the dynamics section of the DBMAX very flexible, while
maintaining the fidelity of the original material. The dynamics section, in combination with a Normalizer, AGC, EQ, De-esser
etc. makes the DBMAX a very powerful tool for optimizing the current signal.
Because the DBMAX can be used in different applications, we propose a few different setups.
Radio Production & Transmission applications
DAB production or FM Production suite
The two applications for the DBMAX in this configuration are:
1. The DBMAX can be inserted pre master, to optimize the production.
2. The DBMAX can be inserted post master to emulate the signal processing in transmission.
Transmission
The two applications for the DBMAX in a transmission situation:
1. Digital Broadcast: DBMAX optimizing, limiting and equalizing the signal for digital Audio Broadcast.
2. FM broadcast: DBMAX optimizing, limiting and equalizing the signal in proportion to the current pre-emphasis.

11
TV Production & Transmission applications
Surround Production Suite
The two applications for the DBMAX in this configuration are:
1. The DBMAX can be inserted pre master, to optimize the production.
Note: Adjusting the L/R balance can cause serious changes to the surround encoded signal.
2. The DBMAX can be inserted post master to emulate the signal processing in transmission.
TV continuity/Transmission
The two applications for the DBMAX in a transmission situation are:
1. Digital Sound: DBMAX optimizing, limiting and equalizing the signal for NICAM (or other systems) using the
wordclock as ext. sync.
2. FM Sound: DBMAX optimizing, limiting and equalizing the signal in proportion to the current pre-emphasis,
generating mono (0º or 90º).
DBMAX SETUP

12
REFERENCE LEVELS
The Reference level settings are the heart of the
DBMAX. If these parameters are not set properly, the
DBMAX may not perform correctly. So please take the
time to go through these level settings and make sure
they are set correctly.
The DBMAX is prepared to match several different predefined
Reference Level setups. These setups could be considered as
“level presets”. In addition to these presets you can store four
setups of your own.
Basic operation
- Use the MENU keys to select parameter.
- Use the ADJUST wheel to change value.
Setup
Load Setup
- Select “Load Setup” by pressing the grey OK key, and
scroll through the list using the MENU keys.
- Select an environment/application resembling your own,
and press OK.
Save Setup
It is possible to store four different custom user setups.
- Place the cursor next to ”Save Setup” using the MENU keys.
- Press OK and use the MENU keys to select the location where
you want to store the setup.
- Confirm with OK to store the preset with the same name or
change the name before storing.
To change the name before storing:
- Use the PARAMETER keys to select letter-position and the
ADJUST wheel to select letter.
- When you have the desired name in the display, press OK to
store the setup with the new name.
All parameters in Ref. Levels will be saved.
Operating Levels
General advice
If you use analog Inputs or Outputs, first adjust the analog levels
In Level setting to define the analog level for digital full scale (FS).
The Ref. Levels setting should be adjusted for
nominal signal level, which is both expressed in dBFS (digital) and
dBu (analog). The Abs. Peak max setting should be adjusted for
maximum instant peak permitted Output level.

13
REFERENCE LEVELS
Ref. Level
With Reference level you can set the reference point of the
Compressor to eg. +4dBu. All Thresholds, except the Limiter
Thresholds, are relative to this parameter.
The Reference level parameter is adjustable in dBu and dBFS.
Abs. Peak max
Sets the hardclip point of the DBMAX. Absolute peak means that
notching occurs above this level digitally.
Absolute Peak Max. is adjustable in dBu and dBFS.
Analog Levels
In Level 0dBFS
Sets the dBu level you want to equal to 0dBFS (Full Scale), i.e.
setting this parameter to +18dBu, means that when you are
sending +18 dBu out of your desk, the DBMAX will be showing
0dBFS.
It is very important that you set this parameter correctly as all
other dBu levels are relative to it.
Trim Input
This parameter trims the level of the analog Input for digital full
scale (FS). Correct trimming optimizes the 24 bit AD converters
performance in conjunction with the trimming of the Output
parameters.
Trim Output
Trims the analog Output level. This parameter may be trimmed
in 1dB steps.
Digital Levels
Input Gain
Sets the digital Input level. Use this if you need to trim a source
to a new level. A typical situation could be trimming down the
digital Output of a CD-player.
All trims may be stored using the Save setup command.
Output Gain
Sets the digital Output level.
Define Overload LED
Overload
This parameter allows you to custom-define the DEFINE LED.
The Overload level can be set anywhere between -30 dBFS
and 0 dBFS.
The Overload parameter is adjustable in dBu and dBFS.
Integration
To simulate different types of meters, the defined overload can
work in proportion to an integration time. Digital meters have an
integration time of 0ms where analog meters typically have an
integration time of 10ms.
The Integration time can be set to 0 ms, 1 ms, and 10 ms.
Front Panel Output Meters
Ref
You can set the Output meters to refer to digital Full Scale
(dBFS), which is the default, or Clip which means that the meters
are referring to “Absolute Peak” as 0 dB. When set to Clip you
will take full advantage from the Output meter.
Peak Hold
Set the desired Peak-Hold time with this parameter.
Choose between Off, 1, 2, 5, or 10 seconds.
Clip LED def.
You are able to define when you want the CLIP LEDs to be
activated. Choose the number of consecutive samples to be at
0dbFS before the CLIP LEDs are activated.
Bypass Definition
Att.
When bypassing the DBMAX in this mode the signal will not
exceed the Abs. peak max level set in the Ref. Levels - I/O
Levels menu.
1:1
Use this setting if you want to bypass the signal but apply Dither
and delay.
Thru
Use the Thru setting to bypass the entire signal bit by bit.
