ACOUSTIC SYSTEMS SUB PF118A, MP112A, MP115

USER MANUALS

GENERAL INFORMATION

Active subwoofer. Corps form- rectangular. Made from – 18 mm birch plywood, corners connected with glue and wooden screws,

painted with structured color.

On the sides have built- in handle, which helps move the acoustic system.

The frontal panel closed with decorative metal grid- painted with powder paint and glued with acoustic foam rubber to protect the

Power amplifier is designed according to class D technology to deliver high efficiency and last heat. Cooling system- automatic.

Power supply source- impulsive.

The amplifier installed low frequency cutoff filters and adjustable crossover filters, used to limit the amplified frequency range.

Input block consists of input control knob, two symmetrical inputs (XLR female), two line outputs (XLR male), crossover filter

cutoff frequency control knob, output signal phase switch.

The line input and output connectors are parallel, i.e. the contacts of the output connector match the respective contacts of the input

connector. This allows to use the amplifier as a signal patching unit (e.g. for supplying a signal to active subwoofer).

Frequency cutoff control knob allows to set up limit of the amplifier bandwidth.

The output signal phase slide switch is provided for 180° reversing of the signal phase in order to achieve the best compatibility of

the sound signal phase of the loudspeaker (in which this amplifier is installed) with other loudspeakers within the same sound

INPUT CONNECTORS

Use the XLR (male) connectors for the input, and XLR (female) connectors for the line output.

Make sure to use only shielded cables whether balanced or unbalanced. Shielding when properly grounded protects a signal against

external radio interference, interference generated by dimmers and other electric noise. Avoid placing input cables close to power

cords or power transformers.

As a rule, unbalanced lines of over 3 meters long are not acceptable. Greater distances require a balanced cable.

Unbalanced connection models with XLR input connectors, contact 3 (Cold "-" ) need to be mutually connected with base contact 1

(Ground)

with protective grounding. To connect the amplifier to awall outlet,

first insert the power

cord into the power cord socket and then plug it into the wall outlet.

UNPACKING

The manufacturers quality control system provides for careful examination of each product before it leaves the factory to ensure its

flawless appearance. After unpacking, please, check the unit for any physical damage. In case of damage, please, contact our local

dealer. Keep the shipping carton and all packing material, as you may require them for re-shipment of the unit.

The amplifier can yield dangerous output voltage! Do not install an energized unit into the speaker system. Do not touch the non-

insulated cable parts connected to the unit in operation!

CAUTION!

The high sound pressure level of speaker systems generated by high output power delivered by the amplifier may be hazardous to

your hearing. Please, take adequate safety precautions.
