Frequently Asked Questions - 660CS JAMO

How do I install the Jamo 660CS in-wall speaker?

Cut a hole in the wall between studs, ensuring it is at least 5/8" from any stud. Install the frame using the dog ears and tighten screws. Connect speaker wires, set impedance, then mount the speaker into the frame with the 6 supplied screws.

How do I connect the speaker wires?

Turn off the receiver/amplifier. Connect positive (+) to positive and negative (-) to negative. Ensure left (L) and right (R) channels are correctly matched. Color-coded terminals: red is positive, black is negative.

Can I adjust the tweeter level?

Yes. The tweeter level switch on the front baffle allows you to lower the output by 3 dB or 6 dB from the factory 0 dB setting. Experiment to find your preferred sound.

How do I set the impedance switch?

The impedance switch is on the crossover at the back. Factory setting is 8Ω. If your amplifier specifies a minimum 4Ω load, you can switch to 4Ω for louder output. For multiple speakers, consult your dealer.

Can I paint the grille and frame?

Yes. Paint the grille and frame separately before mounting. After painting the grille, blow air through the holes to prevent clogging. Use the supplied acoustically transparent foam behind the grille to reduce dark holes.

How do I clean and maintain the speaker?

Dust with a soft, dry cloth. For grease, use a damp cloth with mild detergent. Never use scouring powder, household cleansers, or solvents.

What does the warranty cover?

The warranty covers production and material defects. Electronics (power supply, amplifier) are covered for 2 years; other parts (cabinet, speaker units) for 7 years from the purchase date. Transportation costs are not covered.

What is not covered by the warranty?

Defects from accidents, misuse, normal wear, incorrect installation, modifications by unauthorized service centers, use of non-original parts, altered serial numbers, and force majeure events are not covered.

What should I do if the grille vibrates when the speaker is playing?

Remove the grille and apply the supplied non-curing glue strips at the designated locations, then reinstall the grille. This will prevent vibration and ensure a snug fit.

Can I use the speaker with a 4-ohm amplifier?

Yes. The speaker has a switchable impedance setting. Move the switch to 4Ω if your amplifier requires a 4Ω load. Note that this will make the speaker play louder.

Let's get personal

Placement

Make certain the speaker is located between wall studs to avoid cutting into studs. Place the supplied template a minimum of 5/8" from any studs. Level it and draw a line around it to mark the cutout. Take care when cutting the hole to avoid cutting into pipes or electrical conduits. If you encounter pipes, electrical conduits or other obstacles you may have to select another location for the speaker.

Installation

First install the frame. Loosen screws A (fig. 1) by turning them counter clockwise. Loosen all 4 screws until the „Dog ears“ B (fig. 2) can move freely. Do not remove the screws. Install the frame into the wall and level it (notice TWEETER and WOOFER markings on the frame). Turn screws A clockwise until they are tightened and the frame is firmly installed.

Next install the speaker into the frame. Before installing the speaker connect the speaker wires as described under „Hookup“ and set the impedance switch to the desired position (see “Adjustments”). Remove the grill from the speaker. Place the speaker into the frame and secure with the 6 screws supplied.

Before reinstalling the grill on the speaker make tweeter level adjustments as described under "Adjustments". Reinstall the grill. If the grill has a loose fit and/or is vibrating when the speaker is playing remove the grill, install the supplied non-curing glue strips at locations C (fig. 1) and reinstall the grill.

Hookup

The receiver/amplifier must be turned OFF before you connect the speaker or it may cause damage to the amplifier.

Connect the speaker wires from the receiver/amplifier to the speakers. When connecting the speaker wires make sure that LEFT (L) is connected to LEFT (L), RIGHT (R) to RIGHT (R), POSITIVE (+) to POSITIVE (+) and NEGATIVE (-) to NEGATIVE (-). If terminals are color coded, RED is POSITIVE (+) and BLACK is NEGATIVE (-).

Adjustments

The tweeter can be tilted towards the listening area, due to high frequencies being more directional than low frequencies. The impedance of the speaker and the level of the tweeter are adjustable.

IMPEDANCE:

Located on the crossover on the back. The factory setting is 8 ohm. If the receiver/amplifier specifies a minimum impedance of 4 ohm, the speaker may be switched to the 4 ohm position. This will make the speaker play louder. When installing more then 1 pair of speakers to a receiver/amplifier special care should be taken to impedance matching the speakers to the receiver/amplifier. This may require impedance matching devices. Consult your dealer for information regarding impedance matching.

TWEETER LEVEL:

Located on the front baffle. The factory setting is 0 dB. The level of the tweeter can be lowered by 3 or 6 dB to suite individual tastes in different room environments. Experiment with the settings to find the preferred sound.

Custom painting

The grill and frame may be painted to match your decor. Paint the grill and frame separately before mounting to the wall. After painting the grill blow air through the holes to prevent clogging. The speaker is supplied with a sheet of acoustically transparent foam. This may be inserted behind the grill so the holes look less dark.

Maintenance

All Jamo loudspeakers are made of modern thoroughly tested materials, which will usually require no maintenance, other then dusting or drying with a soft, dry cloth. If the loudspeakers have become greasy, the grease may be removed by moistening the cloth with water and possible using a mild detergent.

NOTE:

Never use any scouring powder, household cleansers or any other solvents for cleaning the loudspeaker.
