3. INSTALLATION
3.1. Placement and mounting
The first thing to take into account when looking for the placement of the
COMPACT 5 is your comfort and an easy access to all the connections.
The COMPACT 5 has 19" (482.6 mm), 3U (132.5 mm) rack mounting ears that allow
you to place it in a standard rack.
Because of the high gain of the PHONO and MIC inputs, the mixer must be placed as
far as possible from noise sources (dimmers, engines, etc.) as well as from any mains cable.
You should never, under any circumstance, remove the metallic cover of the mixer.
The COMPACT 5, being a low consumption unit, does not need any cooling; you
should anyway avoid exposure to extreme temperatures and the operating environment must
be as dry and dust free as possible.
The COMPACT 5 operates under voltages between 90 and 264 V at 47 to 63 Hz.
This device features an over dimensioned power supply that adapts to the mains voltage in any
country of the world with no need to make any adjustments.
In order to protect the mixer from eventual mains overloads, it has a time-lag 0,5 A
(26) mains protection fuse. Should this fuse ever blow off, disconnect the mixer from mains
and replace it with an identical one. NEVER REPLACE THE FUSE WITH ANOTHER ONE WITH A
HIGHER VALUE.
ATTENTION: Changing the fuse must be performed by qualified technical personnel.
3.2. Connectable Signal Sources
- Turntables / Phono: They must be fitted with a magnetic cartridge with nominal
output level between -60dBV and -20dBV (1 to 100 mV). The PHONO (36) inputs of the
COMPACT 5 have a high headroom (margin before saturation) and it can handle higher output
cartridges than what is usual. These inputs are supplied with a nominal input sensitivity of
-40dBV (10mV).
- Microphones: The MIC inputs (20-33) are ready for a nominal input level of -50dBV
(3.16 mV) and are equipped with COMBO connectors. The COMBO connector provides both a
XLR plug and a ¼’’ Jack in the same receptacle. The connection of balanced signals is as
follows:
XLR-3
¼‘’ Jack
Hot or direct signal > Pin 2 Tip
Cold or inverted signal > Pin 3 Ring
Ground > Pin 1 Sleeve
Low impedance (200 to 600) monophonic microphones must be used. In case of
working with an unbalanced connection, the ground pin and Pin 3 (or the ring) must be short-
circuited.
The COMPACT 5 features a Phantom power supply for the connection of condenser
microphones. A switch for general activation of the phantom power can be found on the front
panel of the unit (14) and can be activated using a sharp-pointed object.
