INPUTS - The MS series amplifiers allows you to use two types of input connectors per channel, a XLR female jack for balanced connections and
1/4” TRS female jack that will accept balanced and unbalanced connections. Use these connections to connect the output signal from a mixer,
cross-over or EQ to your MS series amplifiers. A balanced connection is recommended for cable runs longer than 20ft. When constructing your own
XLR cables follow the pin configuration described below for proper connections. For cable runs shorter than 20ft., you may choose the 1/4” TS
unbalanced input option. The 1/4” TS unbalanced input option may be more convenient for most users due to the abundant supply of prefabricated
cables available at your local audio dealer. You may use the two TRS “Input” jacks to jump a parallel connection to another amplifier or other device.
For Example: Connect a XLR cable to the input of channel one. You may now connect a TRS cable from the channel one “Input TRS” jack to the
input jack of another amplifiers channel one input. This will reduce the use of “Y” cables.
OUTPUTS -
BINDING POST/BANANA PLUG: Connect your speakers to the binding post outputs on the rear of the amplifier. The speaker wire may be
connected by bare wire (directly connected, usually for permanent connections), banana plug, or spade connector. Connections are made to
Channels 1 and 2 outputs for Stereo Mode or across the red terminals of Channels 1 and 2 for Mono Bridge Mode.
IMPORTANT NOTICE: Although a speaker will operate with the positive and negative leads plugged into either terminal on the amplifier binding
post, be sure to plug the negative lead into the black terminal and positive lead into the red terminal. Ensuring proper polarity will avoid speakers
being out of phase that can cause a loss of bass response.

OPERATING MODES
STEREO OPERATION : Page 7 / Figure 10 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 counter-clockwise).
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 : 8 Page / Figure 12 details a mono bridge set-up. Be sure your amplifier and all other audio equipment are powered down.
Flip the Stereo/Mono Bridge switch to the Mono Bridge position. Connect an 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 control to regulate your amplifier output.

PROTECTION
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 amplifiers average output can reach it's 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 amplifiers 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 MS series 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.
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.
