Mounting
The best way to place the alpha compressor is to put it on top of a rack. In this position, ventilation will be
optimal and the unit will not heat up too much.
In case you mount it into a 19“ rack or vertically into a console, please leave a free space of about 2cm on top
and bottom so that the air can circulate freely. Also make sure that the rack rails can really carry the heavy
weight: the device weighs about 16kg that should be reinforced from the back in case of doubt. If required,
the four aluminum stands can be unscrewed from the outside of the housing.
Dependent on your personal studio ambience, you might nd the light intensity of the controllers and but-
tons too bright or too dark. This is no problem, because two separate wheel controllers on the back panel
help you to adapt the lights to your particular needs.
Audio Path
Denitely no secret, but still worth mentioning: Inferior cables can noticeably decrease the entire audio
quality; therefore no compromises should be made in this regard. All audio cables should be of a high qual-
ity and as short as possible.
Furthermore, only the processors that are needed every day should be constant parts of the signal chain.
Not all compressors, equalizers etc. feature real hard bypasses; resulting in irretrievable losses of sonic de-
tails. The motto ‚less is more‘ is pretty obvious in this case.
Note: If a noticeable change in level occurs when the compressor is activated, balanced connection might
be the reason. Please look at page 36 for further information.
Warm Up
When the compressor is powered up, it might happen that the Gain reduction meters fully light up even
when there is no audio signal present (depending on the operation mode and the setting of parameters,
both meters might even display dierent values). After a warm up time of about 15 minutes this will be gone
automatically.
All temperature-sensitive circuits will be heated up by then and the compressor is ready for operation. Only
now constant control characteristics and best possible audio quality can be achieved, therefore the warm-
up time must be adhered to before every production.
Safety Instructions
Voltage: Please check if the voltage needed in your country is set correctly at the back side of the unit
before powering it up.
Service: Make sure to have your unit serviced by authorized personnel only and contact elysia for tech-
nical support. Please open the alpha compressor only in case you really know what has to be
done.
Environment: Avoid heat, cold, humidity, vibrations, dust and electronic (e.g. transformers) as well as digital
(digital processors) stray elds.
Cleaning: Clean the unit with a dry, clean cloth. Never use chemical dissolvers or cleansers!
