Alternately, you can connect this terminal to the vehicle’s accessory (ACC) power circuit. Any voltage over +4V DC at this terminal will trigger the MS-8 to turn on.

AUDIO INPUTS

Many factory-installed systems include on-board equalization and crossovers that make simple

connection of aftermarket products difcult. The MS-8 includes the signal-summing circuitry, signalconditioning EQ and time-correction processing that are necessary to reconstruct a at, full-range,

two-channel signal when you use the MS-8 with factory-installed equipment.

Aftermarket head units with line outputs provide a at, full-range, two-channel signal on their front line

outputs, so you need to connect only those channels to the MS-8.

MS-8

CONNeCTiONs

CONNECTIONS

Connecting an aftermarket head unit

If you’re using the MS-8 with an aftermarket head unit that has RCA-type outputs, connect the head unit’s front left and front right outputs to the MS-8’s line inputs 1 and 2 only. Do NOT connect any other head-unit

the input signals and derive as many output signals as your speaker system requires.

IMPORTANT: Do not connect the head unit directly to any ampliers, including a subwoofer amplier. The

MS-8’s signal processing takes nearly 8ms, so any signals connected directly to a head-unit will be ahead of the signals leaving the MS-8 by about 8ms. This difference will cause them to be out of sync with the signals that pass through the MS-8. The MS-8 must generate all the signals that are sent to all of the

system’s speakers!

CONNECTIONS

Connecting a factory radio/head unit

If you will be connecting the MS-8 to a factory-installed stereo or a factory-installed amplier (often located in

the vehicle’s trunk), connect each of your factory front-speaker and subwoofer outputs to one of the MS-8’s Hi Level inputs. Be sure to connect the outputs for all speakers that are part of the vehicle’s front left and front right speakers.

You can connect the factory front speaker outputs to any MS-8 Hi Level inputs, but factory stereo or amplier subwoofer outputs MUST be connected ONLY to the MS-8’s channel 7 and/or 8 inputs. During the calibration/ setup process, the MS-8 will “normalize” the input signals and derive as many output signals as your speaker system requires.

NOTE: The above illustration shows only a general connection example and does not represent any particular vehicle audio system.

Insert the included Hi Level input wiring harness into the MS-8’s Hi-Level-input connector until it locks into place.

IMPORTANT: The MS-8’s Hi Level input wiring harness has gray and white wires. Each channel has a white (positive or “+”) wire and a gray (negative or “–”) wire. Each wire is labeled with its channel number and polarity, and is pre-stripped for easy connection to your factory radio’s speaker outputs. Make sure that the ( + ) and

( – ) wires do not touch each other. Touching wires can cause a short circuit that can damage the MS-8 or your head unit.

To ensure proper polarity, connect each factory-radio positive (+) terminal to the respective “+” terminal on the MS-8. Connect the negative (–) terminals in a similar way.

Aux input: If you will be using a portable music player or CD player as an auxiliary audio-source unit, connect its line or headphone output to the MS-8's Aux input using a cable that terminates in stereo RCA audio connections. You can switch between the MS-8's Head Unit inputs and Aux input in the MS-8's Input Selection menu. See Main Menu, on page 35.

AUDIO OUTPUTS

Congurations

You can congure the MS-8’s eight outputs in a variety of ways, depending on the speakers that are installed in your vehicle. You can congure the MS-8 for a system with one-way (full-range), two-way or

three-way front speakers, a one-way or two-way center speaker, side speakers, rear speakers and one or two subwoofers. Remember, however, that the total number of available channels is eight, so any combination of front, center, side, rear and subwoofer channels cannot total more than eight. For example, if you are allocating six channels for a pair of tri-amped, three-way front speakers, there will be only two remaining channels, which will not accommodate a pair of rear speakers and a subwoofer.

If your system will include more than eight channels, use additional separate ampliers (connected to the

MS-8’s line outputs) for the additional channels. For example, if you want to build a 7.1-channel system that includes bi-amped or tri-amped front speakers, use the MS-8 to generate the 7.1-channel outputs (seven full-range and one subwoofer). Connect the MS-8’s front line outputs to the inputs of an additional

crossover (or amplier containing an additional crossover) that will provide the separate channels required

to drive the front midbass, midrange and/or tweeters separately.

Use the Conguration Chart below to record which of your system’s speakers you have connected

to which of the MS-8’s outputs. Keeping this record will simplify channel assignment during the setup procedure. See Main Menu, on page 35.

If you’ll use the MS-8’s built-in power ampliers to drive your system’s speakers, connect the speakers to the

MS-8’s speaker outputs. Insert the included speaker-output wiring harness into the MS-8’s speaker output until it locks into place. See Main Menu, on page 35.

IMPORTANT: The MS-8’s speaker-output wiring harness’s wires have clear insulation. Each channel has a copper (positive or “+”) conductor and a silver (negative or “–”) conductor. We have labeled each conductor with its channel number and polarity, and pre-stripped it for easy connection to your system’s speakers.

Make sure that the ( + ) and ( – ) wires do not touch each other. Touching wires can cause a short circuit that can damage the MS-8.

TROUBLESHOOTING

sOUNd

Symptom

The source connected to the Aux input is too quiet or too loud.

The sound in all speakers is distorted.

Possible Cause Solution

The Aux input level is not properly set.

The source player’s volume control is set too low.

The MS-8’s System Volume control and the head unit’s volume control are not properly adjusted.

Use the MS-8’s System Levels screen to set the Aux level so that the Aux source’s level matches the level of the head unit source. See Audio Controls Menu, on page 35.

Set the source player’s volume control to a higher level.

If you have connected the front speakers to be driven directly by the MS-8’s

internal amplier, set the

MS-8’s System Volume at –20dB.

If you have connected the front speakers to an external, higher-powered

amplier that is connected

to the MS-8’s line outputs, set the MS-8’s System Volume to a level lower than –20dB.

The MS-8’s Bass Control and/ or Graphic EQ bass bands are set with too much boost, combined with a high System Volume setting.

In either case, you should use the head unit’s volume control to control the system’s volume. You may need to make a minor adjustment to the MS-8’s System Volume setting to allow you to use more of the range in the head unit's volume control.

If you hear distortion when the head unit’s volume control is at higher settings, increase the MS-8’s System Volume to compensate. This change will let you keep the head unit’s volume control within a lower (more distortion-free) portion of its range.

Reduce the Bass Control and/or Graphic EQ boost levels. We recommend never combining high levels of Graphic EQ bass-band boost with high Bass Control boost.

TROUBLESHOOTING

sOUNd

Symptom

The center speaker seems too loud when you’re listening to news, sports or talk radio stations.

The sound always has too much or too little bass or treble.

Music is dull, lifeless and

conned-sounding, with poor

stereo imaging.

Possible Cause Solution

The MS-8’s Logic 7 processing is (by design) sending all mono information to the center speaker.

The MS-8’s Tone Controls and/or Graphic EQ are misadjusted.

The MS-8’s Logic 7 and digital signal processing (DSP) are defeated.

Use the MS-8’s System Levels screen to reduce the center speaker’s level until it sounds correct to you. Then save the settings as one of the MS-8’s Favorite settings so you can recall it whenever you listen to this type of station. See Audio Controls Menu, on page 36, and Favorites Menu, on page 39.

Use the MS-8’s Tone Controls and/or Graphic EQ screens to return all controls to their center positions. See Audio Controls Menu, on page 36.

Use the MS-8’s Audio Controls menu to activate Logic 7 and DSP. See , on page 36.

The MS-8’s System Volume was set at too high a level during the acoustic-calibration process.

Perform the acousticmeasurement portion of the calibration/setup process again, with the MS-8’s System Volume set at –20dB. See Acoustic Calibration, on page 32.
