  PRE OUT

The preamp is equipped with two sets of pre out 

(preamplifier output) connections. They can be used 

for power amplifiers, active sub-woofers or headphone 

amplifiers.

7

  LINE INPUTS

The preamp is equipped with five single-ended, RCA 

line inputs. The gain of the line inputs can be changed 

to equalize the volume of different signal sources. The 

range is between 5 and 15 dB for input 1-4, and be-

tween 1 and 11 dB for input 5. The default gain for all

inputs is 9dB. Please see “MENU FUNCTIONS” for 

guidance.

8

  POWER ON/OFF SWITCH

Toggle the switch to switch between fully off and 

standby mode. When the preamp is in standby mode, 

the power consumption is less than 1W. When the 

preamp is on, the power consumption is less than 12W.

9

  POWER INLET (CAUTION!)

The preamp accepts mains voltages from 100 to 

240VAC 50-60Hz.

The power inlet accepts power cables with an IEC 

60320-C13 female connector.

To ensure the best performance, please consult your 

Aavik Acoustics dealer for a suitable mains cable.

  TRIGGER OUTPUTS

The preamp is equipped with two DC trigger outputs. 

These can be used to power-on power amps, 

sub-woofers and other equipment together with the

preamp. When the preamp is switched on (not in 

standby mode), the trigger outputs will supply 12VDC. 

They can supply up to 80mA total.

ACTIVE CROSSOVER MODULE

Your preamp can be fitted with the optional active 

crossover module. If this is fitted, there are two 

additional sets of line outputs. This module can be 

used for driving the bass section of a speaker with a 

separate amplifier, or for use with subwoofers. 

You can use the high pass and low pass outputs 

together with the regular outputs, so you can supply 

the main speakers with the full frequency range, and 

only supply the low frequency part of the audio to the 

subwoofer for instance. The crossover frequency can 

be set (independently for the high- and low pass 

sections) between 60 and 160Hz.

12

 HIGH PASS OUTPUTS (OPTIONAL)

This set of outputs can be used, if you have a sepa-

rate power amp for the midrange/treble range.

13

 LOW PASS OUTPUTS (OPTIONAL)

This set of outputs can be used, if you have a sepa-

rate power amp for the bass range, or for driving an 

active subwoofer.

WARNING: To reduce the risk of fire or electric shock, do not expose the 

amplifier to rain or moisture.

The lightning flash with an arrowhead symbol within an equilateral 

triangle, is intended to alert the user to the presence of uninsulated 

‘dangerous voltage’ within the product’s enclosure that may be of suffi-

cient magnitude to constitute a risk of electric shock to persons.
