Thank you for purchasing the MCA3545 Bi-Amplifier. It was designed and built to provide years of high quality sound reproduction

when used in active 2-way loudspeakers for music playback, computer sound systems, and home theater applications. The ampli-

fier includes features like user selectable high pass and low pass filters, independent high and low frequency level controls, rugged

independent LM3886TF output devices, and comprehensive internal protection against shorted speaker loads, thermal faults, and

overload conditions.

Features

• User selectable high and low frequency crossover points

• Independent LM3886TF output devices

• Master level control

• Independent high and low level controls

• Switchable 3dB low frequency boost

Front Panel Controls/Connections

1. Power Status LED

The power LED illuminates when the power switch is in the ON

position. After 20 minutes of no signal the unit will go into stand-

by mode and the LED will dim.

2. Power Switch (Off/Auto On)

The amplifier is manually turned ON or OFF via this switch. When

in stand-by mode, (no signal present) the current draw and heat

generated is very low, therefore it can be left in the ON position

indefinitely. The unit will go into stand-by mode if no signal is

present for 20 minutes.

3. Voltage Selector Switch

This switch allows the user to select 115V or 230V operation. The

unit is set at the factory for 115V operation.When operating at 230V

be sure to change the fuse to a slow blow 1A, 250V type fuse.

4. IEC Power Jack

This unit features a grounded IEC type power jack. This allows

the user to change the power cord depending on the country and

voltage used. The IEC jack also houses the fuse holder which

uses 5mm x 20mm, slow blow 250V type fuse. The unit is set at

the factory for 115V operation and is supplied with a USA type

power cord and a 2A slow blow 250V fuse.

5. Level Control

This is the "master" level control that adjusts the overall output level

(both high and low level simultaneously) of the amplifier.

6. Woofer Control

Independently adjusts low frequency output level, to the woofer

only. Adjustment range is 0~+5dB.

7. Tweeter Control

Independently adjusts high frequency output level, to the tweeter

only. Adjustment range is 0 ~ +3dB .

NOTE: Independent woofer and tweeter adjustments allow precise

speaker component balancing, compensating for different levels

in program material and varying room acoustics.

8. RCA Input

RCA connection accepts standard 1Vp-p line level signal. This

is the unbalanced line level input for connection to standard

consumer grade equipment and audio equipment commonly used

in home applications

9. XLR Input

This is the balanced line level input for connection to mixing

consoles and other professional type audio equipment commonly

used in studio applications

Output Connections

Speaker Outputs

There are two sets of speaker outputs located on the rear (PC

board side) of the amplifier module. Each color coded red (+)

and black (-). The black or negative wire features a .110" push

on connector and the red or positive wire uses a .187" push on

connector .Output connections listed below assume you are facing

the rear of the amplifier module (PC board side), with the power

transformer located to the left. Loads on each output lead must

have a nominal impedance of 8 ohm or higher.

Tweeter

This output connection is located on the far right side of the main

amplifier PC board. Note the red and black leads are connected

to corresponding tabs on the PC board labeled T+ and T -.

Woofer

This output connection is located towards the middle left side of

the main amplifier PC board, approximately 2-1/2" from the left

edge of the board. Note the red and black leads are connected to

corresponding tabs on the PC board labeled W+ and W -.
