1. IMPORTANT REMARK
Congratulations! You are the owner of a carefully designed and manufactured equipment. We thank
you for trusting on us and choosing our mixer MAC55i.
In order to obtain the maximum performance of this unit, It is VERY IMPORTANT that you
read this manual before connecting the mixer.
We recommend our authorised Technical Services if any maintenance task should be
needed so that optimum operation shall be achieved.
2. INTRODUCTION
The MAC55i mixer is designed for its use in discotheques, ballrooms, bars, disco bars and
external p.a. applications.
The MAC55i has 5 mixable channels, with 8 stereo inputs: 2 PHONO, 2 CD
(compact disc), and 4 LINE; plus 2 more inputs for balanced microphones.
All channels have a lever switcher input selector, and 3-band tone controls. The MAC55i
also has a removable, externally exchangeable CROSSFADER, assigned to channel 4 and 5 for an
easier DJ mixing.
All inputs are PFL-capable in order to visually (through the VU meters) and acoustically
(through headphones) monitor any signal connected to the unit's inputs.
In the MAC55i, we have cared specially about the roughness, long-time response and
maximum adaptability to the DJ needs, getting a total ease of operation.
3. INSTALLATION
3.1. Placement and mounting
The first thing to take into account when looking for the placement of the MAC55i is your
comfort and an easy access to all the connections.
The MAC55i has 19" (482.6 mm), 6U (266 mm) rack mounting ears that allow you to place
it in a standard rack.
In case you want to install it into a table or a base you should make a hole of 445x260mm.
Keep in mind that all the connections are made on the back panel, so enough space must be
provided for the connection. The thickness of the table or base must not be larger than 12 mm, else
there would not be any physical space left for the connections.
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 MAC55i, 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 MAC55i operates (depending on your country) under 110, 120, 220, 230 or 240V AC
50/60Hz. See characteristics in the back of the unit. You should avoid mixing the mains wire with and
in between shielded signal cables, because this could generate noise and hum.
