QUICK START

This quick start section includes just enough information to get the MP500 operational. For a deeper understanding of speaker and subwoofer connection options, please review the rest of this manual.

The MP500 comes out of the box with the shelf/tabletop feet installed. When rack mounting is desired, these feet can be removed using a Phillips screwdriver. The included rack mount ears can be attached using a T10 Torx driver (not included).
Speaker Connection(s):
Connect a pair of speakers using a Euroblock (aka PhoenixTM) connector (included) which accepts speaker wire from 28 up to 12 gauge.
- Pull both sides of the Euroblock connector to remove it from the MP500.
- Use a small slotted screwdriver to loosen and tighten each contact on the Euroblock when inserting the speaker wire.
- Follow positive (+) and negative (-) indications shown on the Euroblock connector.
- After attaching speaker wires to the Euroblock connector, insert it back into the MP500.
Subwoofer Connection:
Follow the steps in “Step 2” except use the positive (+) and negative (-) indicators for “Bridge Mode” as shown on the text printed below the Euroblock connector on the MP500 chassis.

Stereo and Bridge mode cannot be used simultaneously*
1. Input Connection(s):
  Connect Analog sources using RCA cables. Connect Digital sources using a Digital Coax or Optical cable. When being used to drive a subwoofer, connect the subwoofer out of your source device to the subwoofer input on the MP500. If using the digital inputs, you must select Coax or Optical using the DIP switch on the back of the MP500 (#10 on the image on page 8).
2. Power Connection:
  Insert a power cord into the MP500’s AC input. Plug the cord into a wall outlet. Make sure to respect the voltage rating shown beside the AC receptacle.
3. Volume Control:
  The MP500 has an onboard volume control if needed. How-ever, typically the MP500 will be used with a source that of-fers its own volume control (like a streaming device or used with an AV Receiver when driving a subwoofer). In this case the MP500’s onboard volume control can effectively be used as a basic volume limiter instead. When being used in this manner, you can set the MP500’s volume control to max-imum, and then control the overall volume through your source. If audible distortion occurs, turn down the volume control on the MP500 until the sound no longer distorts.

CONNECTIONS AND BACK PANEL CONTROLS

SPEAKER CONNECTIONS

Depending on the level of the input signal, the voltage at the outputs can be high enough to cause electric shock — be sure that power is off when connecting or disconnecting anything. As well, be sure to use speakers rated for use with this MP500 — an overdriven speaker can pose a fire hazard.

MP500 offers options to power either a stereo pair of speakers (or a system like the MartinLogan Outdoor Living Foundation 8.1 System), or a passive subwoofer (custom install subwoofer.)
When powering a custom installation subwoofer, the MP500 can be configured in “bridged mode” which combines the output of both amplifier channels in order to provide this speaker with more power.

CONNECTING STEREO SPEAKERS

(or MartinLogan Outdoor Living Foundation 8.1 System)

Connect a pair of speakers to the MP500 using a Euroblock (also known as a PhoenixTM) connector. These connectors are included with the MP500 and come preinstalled.

Euroblock connectors accept speaker wire up to 12 gauge. Use speakers as low as 4 Ohms in this configuration.

Remove the Euroblock connector from the MP500 by gently pulling it until it releases.
Use a small slotted screwdriver to loosen and tighten each contact on the Euroblock when inserting the speaker wire.
Connect the red (+) connection on the left speaker to the positive (L+) contact on the Euroblock connector as indicated by the printing located on the MP500 (above the connector) or on the connector itself.
Connect the black (-) connection on the left speaker to the negative (L-) contact on the Euroblock connector as indicated by the printing located on the MP500 (above the connector) or on the connector itself.
Repeat for the right channel.
After attaching speaker wires to the Euroblock connector, insert it into the MP500 by gently pressing it into place.

CONNECTING A PASSIVE

(NON-POWERED) SUBWOOFER
This mode only supports subwoofers rated at 8 Ohms or higher. Bridged Mode increases the amplifier power available for a single speaker. This function is designed for passive subwoofers that require external amplification and can be enabled using the below method:

Remove the Euroblock connector from the MP500 by gently pulling it until it releases.
Use a small slotted screwdriver to loosen and tighten each contact on the Euroblock when inserting the speaker wire.
Connect the red (+) connection of the subwoofer to the positive (Bridge Mode +) contact on the Euroblock connector as indicated by the printing located on the MP500 (below the connector).
Connect the black (–) connection of the subwoofer to the negative (Bridge Mode -) contact on the Euroblock connector as indicated by the printing located on the MP500 (below the connector).
After attaching subwoofer wires to the Euroblock connector, insert it into the MP500 by gently pressing it into place.

CONNECTING DUAL DYNAMO IW SUBWOOFERS

For maximum performance, MartinLogan recommends using an MP500 for each subwoofer in the system. When running 2 subwoofers from a single amplifier is required, the MP500 can drive dual subs in a “bridged parrallel” configuration. Note: This configuration is only recommended with MartinLogan Dynamo IW subwoofers and you must use the “Dual Subwoofer DSP Preset Profiles” as outlined in the DSP Profile Section.

Remove the Euroblock connector from the MP500 by gently pulling it until it releases.
Use a small slotted screwdriver to loosen and tighten each contact on the Euroblock when inserting the speaker wire.
Connect the red (+) connection of each subwoofer to the positive (Bridge Mode +) contact on the Euroblock connector as indicated by the printing located on the MP500 (below the connector).
Connect the black (-) connection of each subwoofer to the negative (Bridge Mode -) contact on the Euroblock connector as indicated by the printing located on the MP500 (below the connector).
After attaching subwoofer wires to the Euroblock connector, insert it into the MP500 by gently pressing it into place.

DIGITAL INPUT

Stereo digital audio sources can be connected using coaxial or optical cables. The MP500 has one digital optical input, and one digital coaxial input. Both of these inputs support the PCM stereo format (up to 24-bit / 96kHz). If using sources that have an option for selecting between PCM and Bitstream (or
Dolby Digital) audio output, select PCM. If the source outputs a non-PCM stream (such as a Dolby or DTS stream), the audio will mute.
Using the DIP switch on the back of the MP500 (See image on Pg. 7) you can select either the Coax or Optical inputs, but only 1 may be used at a time.

ANALOG INPUTS

Connect stereo analog sources using RCA cables.

SUBWOOFER INPUT

The MP500 has multiple subwoofer preset configurations to simplify connection to an AV Receiver or AV Preamp (or source component) with a subwoofer output. Connect the subwoofer output of your preamp/processor/source using an RCA cable to either the Analog RCA (R — right), Analog RCA (L — left), or Subwoofer Input. The Analog RCA (R — right), Analog RCA (L — left) inputs will pass through a low-pass filter before being passed to the amplifier. The Subwoofer Input signal is passed directly to the amplifier. If needed, all three RCA inputs can be used simultaneously.

POWER

Insert a power cord into the MP500’s AC input. Plug the cord into a wall outlet. Ensure that the AC supply matches the voltage rating shown on the back of the MP500.

TRIGGER CONNECTIONS

The trigger connection allows the MP500 to be turned on or off via the trigger input. When the Trig In 3.5mm (1/8”) minijack receives power (5–24 volts DC or AC) from an upstream component, the MP500 turns on (Auto-On delay applies). When it stops receiving power, the MP500 turns off immediately. The
Trig Out jack allows you to run a cable out to daisy-chain and trigger additional MP500’s or another component that uses a trigger in. The trigger out on the MP500 passes through the signal received from the trigger input.

MASTER POWER SWITCH

This switch is wired directly to the AC mains and turns on and off all power going to the MP500.

USB CONNECTION

A USB connection is present for updating the DSP presets available on the amplifier. Instructions for updating the
DSP presets will be provided with the DSP Update file. This connection can otherwise be ignored.

DSP PRESETS

The MP500 is loaded with a variety of DSP presets to both improve performance of the speaker, but also to protect it from being overdriven by the amplifier.
DSP preset availability will change over time, and can be updated via the USB connection on the back of the amplifier. For the most up to date list of presets, please refer to the
MP500 product page on martinlogan.com.
Using the bank of dip switches on the back of the amplifier you
may choose from the following DSP preset options:

FREQUENTLY ASKED QUESTIONS

What is the difference between the stereo analog inputs and the subwoofer input?
The Subwoofer Input

This input connects to the subwoofer output of an AV pro-cessor or AV receiver with bass-management functions as part of its signal routing. It is only active when a subwoofer speaker preset is selected.

The Analog RCA (R — right) and Left (L — left) Inputs

With a subwoofer speaker preset, the Analog RCA (R —right) and Left (L — left) inputs allow a stereo signal source to drive a subwoofer without the voices or other high-frequency content being heard through the subwoofer. This preset enables the subwoofer to be connected to these inputs even when the signal source contains a full range of information. This preset is ideal when the source equipment does not have built-in bass management.
With a Stereo Speaker Preset, the full range signals play through the main speakers.
