MZ-100 Four Channel DSP Zone Amplifier

Introduction:

The MZ-100 is a 4 channel audio amplifier capable of delivering up to 25W RMS per channel. The Digital Signal Processor (DSP) constantly monitors the output signal and optimizes it for maximum fidelity. The onboard microcontroller communicates with external control panels and poly-planar source units to make a complete networked audio solution. The compact, water resistant design allows for flexible mounting possibilities, and makes it simple to expand the audio system capabilities on any vessel or land based application

Uses:

To add additional loudspeakers to a current audio system

To provide amplification for a separate audio zone

As a stand-alone system amplifier for any audio source

Features:

Custom Equalization for optimized sound

Digital Signal Optimization eliminates distortion and maximizes output

Waterproof, corrosion resistant enclosure

Connect up to 4 loudspeakers and 2 subwoofers

Supports Intercom feature

Supports wireless and wired remote control

Expandable for multi-zone use

Includes optional rotary volume knob

Controls, Input and Output Cables:

The switches and gain settings are located behind a watertight plug, which also lights up when the amplifier is on. Be sure to replace the plug when finished with adjustments

1) Input A Level. This rotary control selects the input sensitivity of the amplifiers RCA input (#4). Often referred to as Gain Control

2) Pilot Lamp: (Green) Illuminates when MZ100 is operating.

3) Equalization: These DIP switches are used to set one of eight different equalization settings as shown on page 5.

4) Input A: Stereo RCA audio input for connecting other audio devices

5) Volume Control: Plug for the waterproof remote volume control. When installed, this control will turn off the MZ100 Amp when turned all the way down.

6) Audio System Connection: This plug is used for hooking the MZ-100 to an extended poly-planar audio network using an RT20 System Router.

7) Control Panel Connection: This plug is used for hooking the MZ-100 to poly-planardisplays andcontrol panels.

Power and Speaker Connections: (Refer to diagram on page 4)

7) POWER The Black and Red wires should be connected directly to the 12 Volt battery, power supply or main fuse block using heavy gauge wire (AWG #14 or larger).

BLUE REMOTE WIRE turns on the amplifier. For stand alone or as a local booster amp, connect this to the remote wire of your receiver, an on/off toggle switch or Accessory circuit. As a Zone amplifier with an RD-44 or volume knob, connect this to 12V (Red wire).

8) SUBWOOFER CONNECTIONS: The Violet and Green wires connect to the subwoofers. (if used)

9) SPEAKER CONNECTIONS: The White and Gray Speaker wires connect to stereo pairs of loudspeakers. Make sure the EQ switches are set for the speakers you are using.

Minimum impedance per channel = 2 ohms

Pay close attention to polarity (black stripe = negative).

Unused speaker connectors should NOT be twisted together or grounded. Insulate the contacts and tie them off safely.

Equalization Configurations: The EQ switches (See below) can be set in various configurations in order to accommodate the normal frequency variations found in speakers and installation acoustics. The MZ100 DSP Amp has the unique ability to accomplish this across the full audio spectrum. The chart below shows settings for the broad range of Poly Planar Speakers in Marine and Spa applications. Adding a Subwoofer will further enhance your audio experience.

Make sure the EQ switches are set for the speakers you are using.

When using other brands, use the settings based on similar sized applications.

Connecting the MZ-100 Input (Fixed Gain):

For operation without the optional external volume control, connect the amplifier inputs to the VARIABLE LINE OUT of your receiver using shielded RCA patch cables. In this case the amplifier volume will be determined by the volume setting of the source component.

Connecting the MZ-100 Input (Variable Gain):

For operation with the external volume control, connect the amplifier inputs to the PRE-AMP LINE OUT of your receiver using shielded RCA patch cables. The Pre-amp line output should be a fixed level output that is independent of the volume setting of the receiver.

To VARIABLE line output of receiver, TV, or other audio source.

Troubleshooting:

No Audio, Green LED Off 1. Make sure the Blue remote wired is switched to 12 volts. 2. Make sure the inline fuse is not blown. (Red wire) 3. Check that power wires are getting 12 volts from battery.

No Audio, Green LED On

1. Check that speaker outputs are not shorted to ground. 2. Make sure speakers are connected

Distorted Audio / Audio Cycles on & Off

1. Make sure speaker wires are not shorted together. 2. Power voltage too low or too high. 3. Input signal level too high. Turn down. 4. Power wire gauge too small. Use at least 14AWG wire.

Low Bass Output

Speakers are wired out of phase. Check polarity of wires to the speakers.

Amplifier Keeps Blowing Fuse

1. Battery + and reversed at power leads. 2. Incorrect or shorted wiring. 3. Too many speakers or shorted speaker voice coil.

Whining Noise from Speakers

1. Bad ground connection. Confirm that the black wire returns to battery ground with at least a 14AWG wire.

2. Do not share grounds or power connections with other power electronic equipment such as motors, pumps, and VHF radios.

3. Be careful to route all amplifier wires away from other high current equipment wires.

4. Add a noise filter or ground-loop isolator if all else fails. WARRANTY Poly-Planar marine audio systems are warranted to be free of defects in materials and workmanship for a period of two years.
