Installation; Introduction - Ecler DP 300 Manuel Utilisateur

2. INSTALLATION

The DP300 can be mounted in a standard 19" rack (482.6 mm) taking up one height unit
(44 mm). The plastic washers which are provided can be used to protect the unit from damage during
rack-mounting.
For professional use it is recommended to place the processor in the same rack as the power
amplifiers.
Given the small power consumption of the unit, no ventilation is required. Nevertheless, it is
advisable not to expose the unit to extreme temperatures as well as ensure a dry and dust-free operating
environment.
It is important not to place the processor next to electrical noise sources such as transformers,
voltage dimmers, motors, etc. or their mains supply cables. The metal cover of the device should never
be removed under any circumstance for that same reason.
The DP300 operates with alternate current (AC) between 90 and 264V at 47 to 63Hz. This device
features an oversized power supply which adapts itself to any mains voltage around the world, without
the need of manual adjustment.
Even though the noise produced by powering up is minimum, it is always advisable to follow this
power up sequence: signal sources, mixing unit, processor and, finally, power amplifiers. The power
down sequence must follow exactly a reverse order. By closely following this sequences, all peaks or
transients produced by switching on and off devices do not affect the next devices in the chain and, of
course, never reach the loudspeakers, which are extremely sensitive about this.
