Frequently Asked Questions - 883K4 JAMO

How do I install the Jamo 883K4 speaker?

First, cut a hole using the supplied template, ensuring at least 5/8" from studs. Install the frame by loosening the screws, leveling it, and tightening. Connect wires, set impedance, then attach the speaker with 6 screws. Finally, reinstall the grille.

How do I adjust the impedance setting?

The impedance switch is located on the crossover at the back. Default is 8 ohms. If your amplifier supports 4 ohms, you can switch to 4 ohms for louder output. Ensure proper impedance matching when using multiple speaker pairs.

How do I change the tweeter level?

The tweeter level switch is on the front baffle. It has settings for 0 dB, -3 dB, and -6 dB. Adjust to your preference for different room acoustics. Experiment to find the best sound.

Can I paint the grille and frame?

Yes, you can paint both to match your decor. Paint them separately before mounting. After painting the grille, blow air through the holes to prevent clogging. Optionally, insert the supplied acoustically transparent foam behind the grille.

What is the warranty period for the Jamo 883K4?

The warranty covers 2 years for electronics and 7 years for other parts (cabinet, speaker units, etc.) from the purchase date. Keep your original receipt for service claims.

How should I clean the speaker?

Dust with a soft, dry cloth. For greasy surfaces, use a cloth moistened with water and mild detergent. Never use scouring powder, household cleaners, or solvents.

What precautions should I take when cutting the installation hole?

Ensure the location is between wall studs and at least 5/8" from any stud. Avoid cutting into pipes, electrical conduits, or other obstacles. If encountered, choose another location.

How do I connect the speaker wires?

Turn off the amplifier before connecting. Match left/right channels and polarity: positive to positive (+), negative to negative (-). Use the color-coded terminals: red for positive, black for negative.

What if the grille is loose or vibrating during playback?

Remove the grille and apply the supplied non-curing glue strips at the indicated locations (C in fig. 1). Then reinstall the grille for a snug fit.

Can I use the speaker with a 4 ohm amplifier?

Yes, if your amplifier specifies a minimum 4 ohm impedance, you can switch the speaker's impedance to 4 ohms. This increases loudness. For multiple speakers, consult your dealer for proper impedance matching.

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.
