ME-400 Installation Instructions
10
1. After reading precaution, decide where you are going to install the unit. Also, see
installation diagram.
2. Once the location has been determined, place the amplifier into position. Using a
felt tip pen or pencil mark the four holes to be drilled for mounting. NEVER use the
amplifier as a template for drilling. It is very easy to damage the amplifier surface in
this manner.
3. Remove amplifier. Drill four 3.5mm holes into mounting surface. If you want to mount
the amplifier to MDF or wood panel, drill four 3mm diameter holes into mounting
surface.
4. If possible, test the system to ensure it is operating correctly before final mounting
of the amplifier.
5. Mount the amplifier using the supplied 4 self threading screws.
Mounting
Each channel pair has a set of controls. Channels 1 and 2 adjust together; channels 3
and 4 adjust together.
1. Set to the “HP” (High Pass) position when the amplifier is used to drive a tweeter/
midrange system. The frequencies below the crossover point will be attenuated at
12dB/octave. Permits adjustment of the crossover frequency, by rotating the knob
to select any frequency between 40Hz to 250Hz as the crossover point.
2. Set to the “LP” (Low Pass) position when the amplifier is used to drive a subwoofer.
The frequencies above the crossover point will be attenuated at 12dB.octave.
Permits adjustment of the crossover frequency, by rotating the knob to select any
frequency between 40Hz to 250Hz as the crossover point.
3. Set to the “FULL” position when the amplifier will be used for driving full-range
speaker. The full frequency bandwidth ( 10Hz ~ 35KHz ) will be output to the speak
-
ers without high or low frequency attenuation.
4. Level adjustment – The sensitivity adjustment is to allow the amplifier to work with
many different sources. It allows the input signal to vary between 200 millivolts to 6
volts from the head unit or other signal processor.
5. The “Bass Boost” function can be selected to increase low frequency output. This is
adjustable up to +18dB boost at 45Hz.
