STEREO CONNECTIONS USING THE NEUTRIK SPEAKON OUTPUT CONNECTORS:
Recent regulatory requirements in Europe have outlawed the use of the dual banana plug and force amplifier users to terminate their speaker cables with spade lugs
or bare wire ends. This is not advantageous to most users that want to reconfigure their systems or quickly change out an amplifier. The Neutrik Speakon connector
provides the most convenient solution to this problem, eliminating the need for spade lugs or bare wire end cables. Major speaker manufacturers have been using
Speakon connectors on their products for years, so chances you are ready to use the Speakon connection. With Speakon connectors, you can connect straight from
the amplifier to the speaker. The Speakon connector used on this amplifier meets all known safety regulations. Once wired correctly, the connector cannot be plugged
in backwards, causing the type of inverted polarity situations that have become common with banana hookups. This connection will provide a safe, secure and
reliable method of connecting your speakers to your new amplifier. You can purchase the Speakon NL4FC connectors from your local audio dealer.

Introduction Front Panel Rear Panel Set Up Operating Modes Protection Features SpecificationsSpeakon Assembly
You will need a pair of Neutrik Speakon NL4FC connectors. You will also need high-quality
two or four conductor Speakon cable, a pair of needle-nosed pliers and a 1.5-mm Allen key
to assemble the Speakon connectors to your speaker wire. To assemble the Neutrik
Speakon NL4FC connector, complete the following steps:
1. Strip back 3/4-inch of the cable casing. Strip off 1/4-inch from the end of each of the
conductors down to bare wire, and insert the brass fittings (Figure 9).
2. Slide the wire tensioner (D) and the Speakon coupler (E) through the cable end. See
Figure 10.
3. Insert each wire with the brass fittings into the top of appropriate slot of the connector
insert (B) as shown in Figure 11. Use a 1.5-mm Allen key to tighten the connection
(Figure 12).
4. Be sure to properly match the positive (+) and negative (-) leads of each wire (Figure 13).
5. Slide the connector insert (B) into the connector housing (A), making sure that the large
notch on the outer edge of the insert lines up with the large groove on the inside of the
connector housing. The insert should slide easily through the housing and out the other
side until it extends approximately 3/4-inch from the end of the housing.
6. Slide the cable tensioner (D) along the cable and insert into the housing (A), making sure
that the large notch lines up with the large groove on the inside of the connector housing
(A). The cable tensioner (D) should slide easily into the housing until only 3/8-inch of the
tensioner (D) extends from the back end of the connector.
7. Slide the coupler (E) along the cable and screw it onto the end of the housing (A). Before
tightening, you may want to test the connector to make sure it has been assembled
properly.

INPUT BALANCE
OPERATING MODES
STEREO OPERATION : Page 8/ Figure 14 details an example of a typical stereo set-up. Connect your inputs into channels one and two of the amplifier.
Connect your speakers to the outputs on the rear of the amplifier. Be sure that your front gain controls are turned down to their lowest level (fully counterclockwise). Turn your amplifier on. Turn your input source level up. Use your front gain controls to regulate the output volume. Be sure not to raise the volume to
the clip level, however an intermittent clip signal is acceptable.
MONO BRIDGE OPERATION : Page 9/ Figure 15 details a mono bridge set-up. Be sure your amplifier and all other audio equipment are powered down.
Flip the Parallel/Stereo/Mono Bridge switch to the Mono Bridge position. Connect input signal to channel one. Connect your speaker across the red output
binding post on the rear of your amplifier. Turn your equipment on (your amplifier should always be the last item you turn on). Apply an input source signal to
your amplifier. Use the channel one gain to regulate your amplifier output.
PARALLEL MONO : Parallel ties the two channel line inputs together, so that they will both be driven by the same signal, without the need for external
jumpers or wiring. Both amplifier channels will operate independently. Though they carry the same signal, their gain controls affect only their respective
channels, and they both must use their respective speaker outputs. Never attempt to parallel the speaker outputs, this may cause serious damage to your
amplifier! This mode is recommended when using the MP-2800/MP-4000/MP-5000 to run bass speakers, to achieve better low end. To run in parallel mono
mode connect your system as you would if you were going to run in stereo mode. Then flip the mode switch to Parallel. Be sure the amplifier is off or the power
is disconnected before making any changes.

SUBWOOFER MODE : This mode sends low frequencies to your speakers without the use of an external cross-over. The subwoofer operation can be operated in
stereo, parallel, or bridge modes. Change the different operating modes by flipping the mode switch on the rear of the unit to your desired operating mode. Also, set the
subwoofer mode switch to the ”SUBWOOF” position. Use the frequency selector to adjust the subwoofer output frequency from 20Hz to 200Hz. The different subwoofer
modes are listed as follows:
BRIDGE SUBWOOFER - This operation allows you to get the most possible power out of your amplifier for the sole purpose of running a high powered subwoofer
loudspeaker in mono. To avoid amplifier overheating, never run the amplifier below 4 ohms in this mode. In this mode you may use the frequency adjustment on the rear
of the amplifier, to control the frequency output level. Frequencies may be adjusted from 20Hz to 200Hz. Page 10 / 17 details a typical Bridge Subwoofer set-up.Figure
STEREO SUBWOOFER - This operation is similar to the Bridge Subwoofer operation but in stereo. This operation allows you to run several subwoofers down to a
minimum of 2 ohms. To avoid amplifier overheating, never run the amplifier below 2 ohms in this mode. Set up this mode as you would a standard Stereo set-up. Be sure
both channels are set to “SUBWOOF.” In this mode you may use the frequency adjustment on the rear of the amplifier, to control the bass frequency output level.
Frequencies may be adjusted from 20Hz to 200Hz. Page 11 / 18 details a typical Stereo Subwoofer set-up.Figure
PARALLEL SUBWOOFER - This operation is similar to the Stereo Subwoofer operation but in parallel. When running subwoofers, it is usually recommended to run
them in mono mode to achieve a cleaner tighter low end. This operation allows you to run several subwoofers down to a minimum of 2 ohms. To avoid amplifier
overheating, never run the amplifier below 2 ohms in this mode. Set up this mode as you would a standard Stereo set-up. Be sure both channels are set to “SUBWOOF”
and the mode switch is set to “Parallel.” In this mode you may use the frequency adjustment on the rear of the amplifier, to control the bass frequency output level.
Frequencies may be adjusted from 20Hz to 200Hz.
ONE CHANNEL NORMAL / ONE CHANNEL SUBWOOFER (BI-AMP) - You may also use your amplifier to bi-amp your system. You may use one side of the amplifier
to power a subwoofer and the other side to power a full range speaker. Follow the set up guides listed above to mix and match your operations.

PROTECTION
LIMITER - The MP-2800/MP-4000/MP-5000 amplifiers comes with a built in limiter. When the input signal overloads, the “CLIP LED” indicates a signal overload, at this
time, the volume should be lowered to reduce distortion. If the input gain level is not reduced the built-in limiter will activate. During signal overload, the limiter will reduce
the input audio signal enough to minimize the amount of clipping. A limiter takes the gain of an overloading signal and reduces it, the reduction in gain reduces distortion
that can cause damage to your speakers and amplifier. During normal operation below clipping, and momentary clips on peaks, the limiter does not affect the audio
signal and is inaudible. It will allow brief clipping of peaks and will only activate when continuous hard clipping occurs. During excessive clipping the limiter will reduce
the audio signal enough to minimize the amount of clipping. When the input signal decreases enough that clipping ends, the limiter will deactivate and cease its gain
reduction. The limiter has a fixed threshold and can not be adjusted.
SAFE POWER LEVELS AT DIFFERENT OUTPUT LOADS:
8-Ohm Loads : The amplifier can operate at its rated power level without risk of overheating. However, it may caused excessive temperature if it is pushed hard enough
to continually light the “CLIP” indicator, the amplifier’s average output power can reach its maximum peak.
4-Ohm Loads : If the “CLIP” indicator flashes occasionally, the amplifier is approaching its Maximum long-term power capacity. If it is lit about half the time, the amplifier
channel will probably go into thermal protection within a few minutes.
2-Ohm Loads : Except for an occasional flash, keep the “CLIP” indicator dark to avoid overheating the amplifier channel. Clipping should be kept to a reasonable
minimum. An amplifier’s peak current draw at full output power into 2 ohms is several times what the “normal ” draw is, but its various protection circuits will prevent this
condition lasting more than a minute or two.

SHORT CIRCUIT PROTECTION - The MP-2800/MP-4000/MP-5000 amplifiers comes with built-in Output Short Circuit Protects.
The Output Short Circuit Protection protects the output devices of the amplifier from short circuits and stressful loads. If your speaker
lines shorted, the amplifier automatically detects this problem and discontinued operation for that channel. If one side of your amplifier
becomes shorted and goes into protect mode, the other side will continue to operate normally. Channel output during the “Short Circuit
Protection" will be interrupted (i.e. no sound output). Short Circuit Protection can usually be traced back to the signal output line (i.e.
speaker line). Check the line from the output terminal of the amplifier to the speaker. If this line is good, check the internal speaker
connections and components. A short circuit will usually be traced to a bad cable or a bad speaker component and is rarely traced to
the amplifier itself.

THERMAL PROTECTION - Dual variable speed fans on the MP-2800/MP-4000/MP-5000 amplifiers provide adequate cooling. During low level output the
fans run at normal speeds. During high output and as heat raises, (exceeding 90°C.), the fans will run at higher speeds to aid the cooling process. If the heatsink
temperature exceeds 91°C., the amplifier will mute until the amplifier cools down. When the amplifier cools below 90°C., the amplifier will return to normal
operations. Be sure not to operate your amplifier below the minimum load ratings to reduce the risk of overheating problems.
INPUT/OUTPUT PROTECTION - The input circuits are isolated by resistors. An ultrasonic network uncouples RF from the output and helps to keep the
amplifier stable with reactive loads.
OPERATING VOLTAGE (AC MAINS) - On the rear panel will indicate the correct AC mains voltage. Connecting to the wrong voltage is dangerous and
may damage the amplifier. Always be sure the source voltage for your areas matches the required voltage for your amplifier.
GAIN CONTROLS - The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to a d j ust the
amplifier so no “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion d u ring normal operation.
AMPLIFIER FEATURES:
THRU - THRU will allow the user to daisy-chain one amplifier’s signal input into another amplifier. Plug the signal source outputs into the first amplifier’s input,
patch from the amplifier’s THRU jacks to the next amplifier’s input, and so on, daisy-chaining as many amplifiers as there is no excessive level loss.
LED INDICATORS - Each channel has one red LED indicates signal clipping and one green LED indicates input signal is present.
FUNCTION INDICATORS - These green/red/yellow LED indicators detail the amplifiers current operating mode (Stereo, Parallel, or Bridge).
