4.10. Cutter / Transformer

Both Cut Switches (32-46) found inside the HAK320 are high quality C&K components,

which have, proven through the years their excellence due to their great precision and endurance.

Using them, you can perform (similar to a "hard" set fader) total cuts to the respective

channel. If this cut-off is done rhythmically to the beat, you will achieve the famous Transform effect.

The direction of the Cut switch can be reversed or customized individually after

unscrewing the front cover (Sec 4.6).

Headphones: in order to obtain a high performance, these should be of the high

impedance type (200-600). Plug them to the PHONES output (52), in the front panel, by means of

a standard stereo jack. Sleeve is Ground, Ring is Right Channel and Tip is Left Channel.

The HAK320 has two main outputs OUT1 (9-11), balanced XLR 3, 0dB on 600 and

OUT2 (8) RCA, 0dB on 1k with their own volume control by using a rotary knob to adjust the output

signal. Jumpers (Fig 2) can internally adjust main outputs to +6dBV (2V).

CAUTION: Changes on the Output Level have to be performed by a qualified technician.

ATTENTION: You must be careful when setting up the general output level of the

mixer. The "clip" display of the connected power amplifiers must never remain permanently lightened

up, but do it occasionally by following the rhythm of the bass signals that are being played.

The HAK320 mixer has a REC (13) output of 0dBV nominal on 10k load.

Ensure at all times that no signal sources reaching the mixing desk and no devices

connected to its output have their earths interconnected; that is, earth should never reach them via

two or more different paths, as this could lead to humming which could even interfere with sound

reproduction quality. In order to avoid earth loops, ensure that the shielding of cables, if connected to

the chassis, are never connected with each other.

As a general rule of thumb, make the signal connections as short as possible and use the

best connectors and cable available. Cables and connectors are frequently held cheap, forgetting

that a bad connection can result in a poor sound quality.
