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 HAK310 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 HAK310 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 (6) of the HAK310 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).
