4.5.1 Equalizer (optional)

A three-band equalizer is available for input channel 1 and 2. Use the following controls to set

the equalizer according to your needs:

• 80 Hz and 8 kHz: bass and treble adjustments are achieved by using two separate

±15 dB knobs.

• MF: medium frequencies adjustment is achieved by using one knob to progressively

adjust the central frequency from 180 Hz to 8 kHz, and by using another knob to

adjust the amplitude within a ±11 dB range.

4.6 Internal Settings

Please pay attention that these internal adjustments must be executed by a qualified technician

or by a SONOSAX appointed distributor or dealer. Any damage due to manipulations inside the

unit cancels the SONOSAX warranty immediately. See the appropriate schematic for proper

jumper or trimmer location.

To access all internal settings (jumpers and trimmers), you have to open and remove the

anodized cover located in the middle of the Bottom Panel (see 4.5). Simply unscrew the two

slotted screws present on the Bottom Panel and remove the anodized cover with care to avoid

damaging the cables and connectors that may be present if you have the optional equalizer

installed.

4.6.1 Headphones level adjustment

The two trimmers T3 (Left) and T4 (Right) located on top middle of the Front Board (see 5.4)

allow you to precisely adjust the nominal headphones output level The factory setting is 0dBu

for both channels on position 3.

NOTE: As all positions of the PHONES switch have a fixed step of 6dB among them, you only

have to adjust the nominal output level of position 3 to shift up or down the whole

output level range.
