The HAK320 features 2+2 mixable channels (channel one, channel two, session, mic),
with 5+1 stereophonic inputs and one microphone input (2 Phono, 2 Line, 1 Session, 1 Microphone).
Two main channels feature a three band equalizer, gain control, and PFL function in order to display
its level directly on the VU-meter and hear it through the headphones.

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 HAK320 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 HAK320 operates under 110, 120, 220, 230 or 240V 50/60Hz, depending on the
country, (see characteristics in the back of the unit). 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 250mA 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
177mV nominal output level. The PHONO inputs (15-7) of the HAK320 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 (15-7) and
that the turntables ground cable is connected to the HAKs GND (19).
