4. OPERATIONS

Setting system volume

1. Turn the master volume and subwoofer level controls to their minimum settings.
2. Turn the source unit on and increase the volume until you hear distortion.
3. Reduce the volume to just below the distortion point (approximately 80% of full volume).

This is the maximum usable musical signal for the source unit. Turning the volume beyond this point increases noise and distortion without increasing the musical signal.

Note

Once you set the source unit volume, do not change it. Always use the volume control on the EQS755 as the master (main) volume control. The EQS755 has better electronics, a higher sound to noise ratio, and is more linear than the volume settings on any source unit available.

Adjusting the controls

The EQS755 provides a graphic adjustment band for each of seven frequency ranges: sub, low, mid, mid-high and high frequency. You can adjust the center of each frequency band to fine tune the acoustical response to your vehicle's interior.

1. Set all frequencies to the center position. The small dot on the control knob should be set at 12 o'clock.
2. Play your favorite music track and adjust the individual controls to suit your taste. Avoid extreme settings, which can distort musical peaks.
3. Increase or decrease the equalizer gain controls to suit your taste.
4. If your system includes a subwoofer, slowly increase the subwoofer level until you hear a solid bass.
5. If your system includes rear speakers, adjust the fader control to add rear sound. Set it so most of the music comes from the front and only fills the rear.

Setting the low-pass frequency

Set the low pass frequency switch on the top of the EQS755 to either 60Hz or 90Hz depending on the subwoofer and subwoofer amplifier requirements.

Connecting an MP3 player or video unit

1. Plug the MP3 player or video unit into the auxiliary RCA input on the back of the EQS755 unit.
2. Make sure the auxiliary button on the front of the unit is out, ready to receive input from the main RCA input (not the auxiliary RCA input).
3. Turn the EQS755 master volume to a normal listening level.
4. Press the play button on the auxiliary source.
5. Push in the AUX button to change to the auxiliary source.
6. Using a small flathead screwdriver, adjust the AUX gain controls located on the top of the unit so that the volume of the auxiliary source matches the volume of the main source.

Notes (A):

1. With AUX S / W button in out position you can select either Hi Input or Main in. 1.1 Do not use Hi Input and Main at same time; doing that it will cause mixing sounds, causing too much distortion in the audio.
2. With AUX S/W button in position you can select the AUX IN function.

Using the front panel 3.5mm input

1. Reduce the EQS755's volume to minimum before plugging the 3.5mm cable to avoid any sudden, unwanted changes in output.
2. Plug the 3.5mm cable into the EQS755 AUX input. The EQS755 will automatically select this input when the cable is inserted.
3. Turn the EQS755 master volume to a normal listening level.
4. To go back to the main input, simply reduce the master volume and gently unplug the 3.5mm cable from the EQS755.

Note: Unplugging the source device will not change inputs. You must remove the cable from the EQS755

Care and maintenance

Cleaning the cabinet

Use a soft, dry cloth to gently wipe dust and dirt from the unit.

Do not use benzene, thinner, car cleaner, or other cleaners. These substances may damage the unit or cause the paint to peel.

Servicing the equalizer/crossover unit

In the event that trouble arises, never open the case or disassemble the unit. The internal parts are not serviceable by the user. Opening any components will void the warranty.

CAUTION

Changes or modifications to this product that are not approved by the manufacturer will void the warranty and will violate FCC approval.

5. INSTALLATION AND WIRING

Read these instructions and the following precautions carefully.

What is included in the box

In addition to this manual, the box contains:

EQS755 7-band graphic equalizer
- 2 mounting brackets
8 Phillips-head screws

Before starting

Mounting precautions

The EQS755 can be mounted next to the source unit or under the dash using the mounting brackets. The front panel controls should be easily accessible from the driver's seat. In addition:

This unit requires additional mobile audio components for proper operation.
- Always use great care when attaching anything to a vehicle! Check clearances in front of, behind, and on both sides of the planned installation before drilling any holes or installing any screws.

Wiring precautions

Disconnect the ground (-) terminal on the vehicle's battery.

WARNING

To prevent short circuits during installation, always disconnect the vehicle's negative (-) battery lead before making any connections.

This unit is exclusively for vehicles with a negative ground, 12V battery system.
- A good chassis ground connection is critical to minimize resistance and avoid noise problems. Use the shortest wire possible and securely connect it to the car chassis and the source unit ground.
- When routing RCA cables, keep the cables away from the power cables and output speaker wires.
- If you are using a source unit without a remote turn-on lead, the EQS755 can be turned on with a switched accessory lead. This accessory power source is located in the factory harness at the back of the radio. This lead turns on and off with the ignition key
- Do not open the case. There are no user-serviceable parts inside. If you require assistance, consult your Clarion dealer or an authorized Clarion service center.

Tools and additional components

You will need:

• A Phillips-head screwdriver when mounting the unit in the vehicle.
• A small flat-head screwdriver to adjust the AUX gain controls if you connect an MP3 player or video source.
  High-quality RCA input and output cables.

Extra cable can cause signal loss and act as an antenna for noise. Use only highquality RCA cables that are no longer than necessary to make a direct connection with the source unit and amplifiers.

7.GLOSSARY

Crossover: A device that limits the range of frequencies sent to a speaker or amplifier. Equalization: the process of boosting or cutting sound signal frequencies to improve the quality of the sound. The term comes from the filters used to add back high frequencies at the receiving end of analog transmissions over wires.
Equalization band: the frequency range impacted by a specific filter.
dB: decibel, a measurement of the relative difference in power or intensity between two acoustic signals
Gain control: gain is the amount of amplification (voltage, current or power) of an audio signal expressed in dB
Graphic equalizer: a multi-band variable equalizer that uses mechanical controls to adjust amplitude.
Hz: Abbreviation for Hertz, a unit of frequency equal to one cycle per second.
Octave: the musical principle of dividing sound frequencies into the eight notes of the musical scale.
OEM: Original Equipment Manufacturer
RCA input/output: port through which sound travels in and out of the system; "RCA" refers to the type of connector, which was originally manufactured by Radio Corporation
of America.
Slope: how fast the sound changes rated in dBs. The higher the dB number, the faster the frequency drops off.
