AUX IN

These RCA-type connectors allow the connection of stereo

signal sources (e. g. CD/MD-Player, Tape Deck,...). The ste-

reo input signals are internally summed for monaural output.

Caution: Before connecting or unplugging an appliance,

make sure to turn the AUX LEVEL control all the way down

(counterclockwise). This helps to protect the audience

and you from unpleasing knack noise.

AUX LEVEL

This control is used to adjust the input level of the signal source

that is connected to AUX IN.

ACOUSTIC PROCESSING

The ACOUSTIC PROCESSING section is not what you would

call the 'usual' sound control section, like the ones found on a

mixer for instance. What's more, the ACOUSTIC PROCES-

SING section provides the possibility to very efficiently match

the desired sound of the AM12 to existing acoustic conditions.

Using the controls lets you alter the AM12's frequency respon-

se up to the margins as shown in the below diagram. When

altering the sound, it is always good advice to start with all

controls set to their neutral positions - all controls centered -

and to adjust their setting by cautiously turning the controls.

HI control

The HI control allows amplifying or attenuating the high-fre-

quency range of the signal by ±10dB.

MID control

Turned all the way to the right (clockwise), the MID control is

set to its neutral position, i.e. the signal's mid-frequency range

is unaltered. Set the control to its counterclockwise margin for

6dB attenuation. Therefore the MID control provides a way to

efficiently prevent acoustic feedback noise. The MID control's

cutoff frequency is at 4 kHz. Experience has shown that with

most set-ups in this frequency range feedback noise tends to

occur.

LO control

The LO control incorporates the DYNACORD's patented Lo-

Pass notch filter. Using the LO control lets you increase the

audio signal's low frequency range level. The signal is unalte-

red when the LO control is set to its neutral position, i.e. turned

all the way down (counterclockwise). Setting the control to its

clockwise margin causes a level increase of 12dB.
