Operation Safety

DE-COMPRESSION:

converts the compressor to an intelligent upward expander that
allows you the de-compress highly compressed audio signals,
such as samples, keyboards sounds or previously recorded tracks
that have been overcompressed. For example, the sounds used in
most drum machines are highly compressed, but processing
them via the De-compress mode restores their dynamics and
vitality.

Each channel incorporates a NOISE GATE with ARC (Auto-

Release-Circuitry), and this too is highly automated. In a maste-
ring situation, it may be used to provide click-free gating at the
beginning and the end of a song. The CLOSE-LED indicates when
the NOISE GATE shuts.

Both channels of D

YNA

M

AXX

are equipped with a 20-digit LED

ladder meter displaying gain changes to a resolution of 1dB. The
displayed values range from -10dB to +9dB.

Each channel also has an additional SIGNAL-LED which illumi-

nates when the input signal is hotter than -40dB.

If it is required to patch in external processing, both left and

right channels have SIDE CHAIN inputs. If an acceptable sidechain
signal is being received, a LED on the front illuminates.

When processing stereo material, the STEREO COUPLE function

should be switched on so that both channels produce the same-
degree of gain change. This is necessary to maintain a coherent
and stable stereo image. The front panel controls, including the
ACTIVE switch of channel 1, function as master controls in STEREO
COUPLE mode.

The housing of the D

YNA

M

AXX

has the standard 19"- EIA format

and occupies 1U (44.45 mm) in your rack. When installing the unit
in a 19"-rack, the rear side of the unit needs some support, especi-
ally in a touring case.

The D

YNA

M

AXX

should not be installed near units which produce

strong magnetic fields or extreme heat. Do not install the
D

YNA

M

AXX

directly above or below power amplifiers.

Check that the voltage details quoted on the back panel are the

same as your local mains electricity supply. Use a minus (-)
screwdriver to set the voltage selector to the voltage for the area
in which the unit will be used.

Never cover up the ventilation slots on the top of the unit. If,

during operation, the sound is interrupted or indicators no longer
illuminate, or if abnormal odor or smoke is detected, or if liquids
are spilled on the unit, immediately disconnect the power cord
plug and contact your dealer.

Only clean your D

YNA

AXX

with a soft, lint-free cloth.
