3. INSTALLATION

3.1. Placement and mounting

The first thing to take into account when looking for the placement of the COMPACT 8 is your

comfort and an easy access to all the connections.

The COMPACT 8 has 19" (482.6mm), 4U (177mm) 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 8, 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 8 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 (32) 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 (38) inputs of the COMPACT 8 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 (23-27) are ready for a nominal input level of -50dBV (3,16 mV)

and are equipped with COMBO connectors. The MIC ATT switch on the rear panel (28) allows a 20dB
attenuation on the input sensibility, so that it is changed from –50 to –30dB (3,16 to 31,6 mV). 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 of a TRS Jack) must be shortcircuited.

The COMPACT 8 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 rear panel of the
unit (30). The supplied phantom power is 18 VDC.

- LINE Inputs. The sensibility of the line inputs (13-37-38) is rated at 0dBV (1V). CD, DAT, MP3,

DVD Audio Players, Tape recorders, cassettes, tuners or videos should be connected to LINE inputs.

Additional line level sources may be connected to the “AUX 7” (13) input, which is located on the

front panel and is electrically linked to channel 7.

- Headphones: In order to achieve the best performance, they should be high impedance type

(200-600

). They must be connected to the headphones out (22) connector, a standard 1/4" stereo jack.

Connect ground to sleeve, ring to right and tip to left.

- Power amplifiers: See paragraph 4.6.
