RAM Audio AS 1K5 DSP Power Pack ASYM Series
Module Assembly
Installation Requirements
For the installation of the ASYM module, you need an internal chamber inside
the acoustic enclosure, separate from the chamber where the speaker is
mounted. If preferred, the ASYM module can be supplied with a rear metal case
for this purpose, avoiding having to make this space airtight.
The module is fixed to the enclosure with 8 M4 or M5 screws, sealing foam
should be placed in the joint between the module and the box to avoid
vibrations (it is not advisable to put foam in the joint between the module
and the optional rear metal case).
In the drawings below you can see: (1) the external dimensions of the module
(front/profile), (2) the optional rear metal case, and also (3) the
recommended machining of the acoustic enclosure.
Connection and Description
Speakers Connection
The connection of the speakers to the module is done using two JST VHR-2N
connectors provided. A cable should be crimped to the terminals (1.25mm2
section maximum) and placed on the connector box, so that the metallic tab
fits into place.
The connection is as follows: 
front Panel Description
-
Signal Input: Female XLR Connector for signal input.
-
Signal Link: Male XLR Connector for the signal link.
-
Ethernet Connectors: RJ45, two ports Ethernet switch.
-
USB Connector: B type USB connection.
-
LED ON: power supply ON. Blinking indicates StandBy mode. LED SIGNAL: input signal presence indication.
LED LIMIT: lights when the DSP limiters are working.
LED CLIP: the maximum input or output has been reached. -
Quick Preset: press the button for 3 seconds to change the desired output preset.
ON: press the SET1 button for 2s to turn on (in StandBy mode). LEVEL: push SET 3-4 buttons simultaneously to enter LEVEL mode (both LEDs light up).
Then use 3 and 4 to change the level. -
Mains connection: inlet and outlet powerCON True1 connection. It works also as a main switch, as it is a connector with breaking capacity.
