3. INSTALLATION

3.1. Placement and mounting

The first thing to take into consideration when placing your HAK is your comfort and an easy
access to all the connections. The HAK380 is basically conceived as a tabletop mixer and its usual
placement will be between two vinyls or CD players. The optional metallic side profiles kit allows you to
firmly fix your HAK to the surface over which it is placed or over its own profiles (Fig.1). These profiles
also allow to tilt the mixer's position for an easier operation.
Because of the high gain of the PHONO and MICROPHONE inputs, always try to place the mixer
as far away as possible from noise sources (dimmers, engines, etc.) and mains wires. For the very
same reason, and under any circumstance, you should never remove the unit's metallic cover.
The power consumption of the HAK is very low, so they don't need any cooling, but you should
avoid extreme temperatures and the atmosphere should be as dry and dustfree as possible.
The HAK380 operates now with a new universal input power supply "Switching Power Supply"
and can perfectly works without any internal modification from 90V to 264V – 47 to 63Hz. Make sure that
the mains-wire is far away from the signal-cables in order to avoid any possible audio hum.
In order to protect the unit from an eventual electrical overload it carries a 500mA fuse. Should it
ever blow up, unplug the unit from mains and replace it with an identical one. If the new fuse blows
again contact immediately with our authorized technical service.
ATTENTION: NEVER SHORT-CIRCUIT THE SECURITY PATH NOR USE A HIGHER
VALUE FUSE.
CAUTION: Fuse substitutions have to be performed by a qualified technician.

3.2. Input signal sources

3.2.1. Turntables

Turntables need a phono cartridge and an intact needle. Consider using specialized cartridges
and needles for hard scratching application. Remember also to replace the needle approximately every
500 hours of use. Turntables must be fitted with magnetic cartridges of 5.6 to 140mV nominal output
level. The PHONO inputs (12) of the HAK380 have a very good headroom so they can accept high
output level cartridges. If you use low output, moving coil cartridges, you will need to use an external
preamplifier, placed as near as possible to the turntable and connected between the cartridge and the
mixer.
Please take care on the correct assignment of channels to the Phono inputs and that the
turntables ground cable is connected to the HAKs GND (4).
