SUBWOOFER OUTPUTS

The M1000/5v2’s single subwoofer channel is

designed to deliver power into subwoofer loads

equal to or greater than 2 ohms. It is rated for

600W into 2 ohms, 500W into 3 ohms and 400W

into 4 ohms (Continuous Power, RMS Method).

Subwoofer loads below 2 ohms nominal are not

recommended and may cause the amplifier

to initiate a protection mode which reduces

power output.

The M1000/5v2’s subwoofer outputs are

designed to accept 16 AWG - 8 AWG wire. To

connect the subwoofer wires to the amplifier,

first back out the set screws on the top of the

terminal block, using the supplied 2.5 mm hex

wrench. Strip 1/2 inch (12 mm) of insulation

from the end of each wire and insert the bare

wire into the terminal block, seating it firmly

so that no bare wire is exposed. While holding

the wire in place, tighten the set screw firmly,

taking care not to strip the head of the screw.

You will notice that there are two “+” positive

connections and two “–” negative connections.

This is to facilitate multiple subwoofer wiring.

The two positive and two negative connections

are connected in parallel inside the amplifier

They are not stereo outputs. Connecting two

subwoofers, each to one set of positive and

negative terminals, will result in a parallel

subwoofer connection. If only connecting one

pair of subwoofer wires, it is not necessary to use

both sets of connections.

SPEAKER OUTPUTS

The M1000/5v2’s speaker outputs are designed

to accept 16 AWG - 8 AWG wire. To connect the

speaker wires to the amplifier, first back out the

set screws on the top of the terminal block, using

the supplied 2.5 mm hex wrench. Strip 1/2 inch

(12 mm) of insulation from the end of each wire

and insert the bare wire into the terminal block,

seating it firmly so that no bare wire is exposed.

While holding the wire in place, tighten the set

screw firmly, taking care not to strip the head of

the screw.

Each pair of the M1000/5v2’s main channels are

designed to deliver power into speaker loads equal

to or greater than 2 ohms when using a “stereo”

configuration and speaker loads equal to or greater

than 4 ohms when using a “bridged” configuration.

The subwoofer channel is designed to deliver power

into subwoofer loads equal to or greater than 2 ohms.

Speaker loads below 2 ohms nominal

per channel (or 4 ohms bridged) are not

recommended and may cause the amplifier

to initiate a protection mode which reduces

power output.

BRIDGING CONSIDERATIONS

Bridging is the practice of combining the

output of two amplifier channels to drive a single

load. When bridged, each channel produces

signals of equal magnitude, but opposite polarity.

The combined output of the two channels

provides twice the output voltage available from a

single channel. The M1000/5v2 has been designed

for bridging of its main channel pairs without the

need for input inversion adaptors.

To bridge a pair of main channels, use the

“Left +” and “Right –” speaker connectors only

(the “Left –” and “Right +” remain unused). Each

bridged channel pair will deliver optimum power

into a 4 ohm load.

When a pair of the M1000/5v2’s main channels

are bridged, they will deliver 200W x 1 into a

4 ohm load or 150W x 1 into an 8 ohm load.

Operating a pair of bridged channels into a

load lower than 4 ohms is not recommended.

A bridged pair of channels requires that both

channels in the pair receive input. You must

connect the mono or stereo source signal to

both the left and right inputs of the bridged

channel pair. Connection of only one input

will result in reduced power output, increased

distortion and can cause the amplifier to

overheat. Do not do this!

When a pair of the M1000/5v2’s main channels

are operating in bridged mode, the output will be

in mono (only one channel). This mono channel

can contain only right channel information, only

left channel information, or the sum of the signals

from right and left input channels. In order to

achieve one of these options, configure the inputs

to that pair of channels in one of these two ways:

1) Left Channel Only or Right Channel Only

Information: If you wish to send a left-only or

right-only signal to a pair of the M1000/5v2’s

channels you must use a “Y-Adaptor” to split

the single channel signal into both left and

right RCA inputs of the bridged channel pair.

This option is used when deploying a pair of

the M1000/5v2’s main channels to drive left

channel speakers only and the other pair of

the M1000/5v2’s main channels to drive right

channel speakers only.

2) Left + Right Channel Information: When

bridged and fed by a stereo source signal, a

bridged pair of the M1000/5v2’s channels will

automatically combine the left and right input

signals into a summed mono (left + right)

input signal.

STATUS LED / PROTECTION CIRCUITRY

There is a single multi-color LED on the top

surface of the amplifier to indicate the amplifier’s

operating status.

Marine 5 Channel Amplifier with 2-Way / 3-Way Crossover

1) Flashing Green: amplifier is powering up, audio

output is muted.

2) Constant Green: amplifier is on and functioning

normally, audio output is active.

3) Constant Red: Indicates that the amplifier has

exceeded its safe operating temperature, putting the

amplifier into a self-protection mode, which reduces

the peak power output of the amplifier. When its

temperature returns to a safe level, the red light will

return to green and the amplifier will return to full-

power operating mode.

4) Constant Amber (yellow): Indicates that an over-

current condition has occurred and is accompanied

by a muting of the affected channel(s). Because the

muting behavior may be very short in duration, it

may manifest itself as an audible, repetitive ticking

noise in the output. Over-current conditions can

be caused by a speaker impedance lower than the

optimum load impedance range for the amplifier or

a short-circuit in the speaker wiring. The latter can

result from a short circuit between the positive and

negative speaker wires or between either speaker

wire and the vessel chassis. The “Status LED” will

remain amber for a few seconds, even if the over-

current condition is of a very short duration. This

functionality can be used to diagnose a short-circuit

by only connecting one channel at a time. The

“Status LED” will turn amber when you connect

the channel that is experiencing the problem and

turn the volume up.

5) LED off / Amplifier Shuts Off Unexpectedly

The only condition that will shut down

an undamaged M1000/5v2 completely is if battery

voltage or remote turn-on voltage drops below

10 volts. The “Status LED” will turn off when

this occurs. The amplifier will turn back on

when voltage climbs back above 11 volts. If this

is happening in your system, have your charging

system and power wiring inspected.
