Frequently Asked Questions - BS 650B Glemm

How do I switch between 8 Ω and 70/100 V operation?

Use the selector on the rear side of the speaker. Rotate it to the 8Ω symbol for low impedance mode, or select the desired power tap for constant voltage mode (70 V or 100 V).

What power settings are available for 70 V and 100 V systems?

For 70 V operation, selectable RMS powers are 5, 10, 20, 40 W (10, 20, 40, 80 W max). For 100 V, selectable RMS powers are 10, 20, 40 W (20, 40, 80 W max). These values are indicated on the selector: black on grey for 70 V, white on black for 100 V.

How do I connect the speaker wires?

Remove the green terminal block from the bracket’s back side. Loosen the two screws, insert the cables (red +, black -), tighten the screws, and reinsert the block into its housing. Ensure proper polarity.

Can I connect multiple speakers in 8 Ω mode?

Yes, you can connect speakers in series or parallel (see Fig.1 in manual) to achieve a final impedance within the amplifier’s range (typically 4–16 Ω). Ensure total power does not exceed amp rating. Incorrect impedance may damage equipment.

How do I connect multiple speakers in a 100 V system?

Connect all speakers in parallel (see Fig.2). Connect the black wire to the amplifier’s COM terminal and the red wire to the 100V terminal. Use correct cable gauge for distance and ensure total speaker power does not exceed amplifier power.

What is the recommended installation procedure?

First, mount the wall plate using supplied screws and anchors. Attach the bracket to the plate with the screw in hole A. After connecting cables, mount the speaker on the bracket. Use the safety cable: fasten it to hole B on the speaker back and to a screw on the wall plate to prevent falls.

How can I adjust the speaker direction after mounting?

Loosen screw D to tilt the speaker in any direction, then tighten the screw once the desired position is achieved.

What safety precautions should I take?

Ensure the amplifier is off before installation. Do not expose the speaker to water, flammable liquids, or metal objects. Do not open or disassemble the product. If a serious problem occurs, stop use and contact authorized service center. Always use the safety cable to prevent falls.

How do I clean and maintain the speaker?

Use a dry cloth to clean the exterior. Avoid using water or solvents. Regularly check the safety cable and mounting for tightness. For any repairs, contact the authorized technical service center.

Where can I find warranty and support information?

Warranty is according to national and European regulations. For complete warranty conditions and technical service, visit www.glemm.eu or www.karmaitaliana.it. Register your product on the website to receive updates.

WARNINGS

Read and follow strictly the instructions contained in this manual. Keep this manual for future reference and include it if you give the product to another user.

The installation of the product must be carried out exclusively by specialized technicians, skilled in electric and audio systems. In case of wrong installations or connections the manufacturer doesn't take any responsibility for damages to people or objects. Do not open the product, do not disassemble and don't try to operate inside it. Do not allow water flammable liquids or metal objects to enter the product. In the event of a serious operating problem, stop using the product immediately. Never try to repair it by yourself, but contact the authorized technical service center.

SETUP AND CONNECTION

To set the desired operating mode, use the selector on the rear side of the speakers. If you need to make a low impedance connection, by means of a screwdriver, rotate the selector and set it on the 8Ω symbol. If you mean to make a constant voltage connection, select the adequate power. When operating at 70V you must consider the powers indicated in black on grey background (1.3/2.5/5/10W). When operating at 100V you must consider the powers indicated in white on black background (2.5/5/10W). The values refer to RMS powers (around half of max power).

To connect the cables take off the green terminal block on the bracket's back side. Loosen the two screws and insert the cables into the terminals, taking care to respect the polarities (red +, black -). Position then again the terminal block in its housing.

8Ω WIRING

If you wish to connect the speaker to a low impedance system, insert the red + and the black - wire into the amplifier's output socket. If you need to connect several speakers, after checking the total power, you can make series or parallel connections (Fig.1) in order to obtain a final impedance supported by the amplifier (usually 4-16Ω).

Wrong impedances could seriously damage the connected fixtures.

100V WIRING

For the connection of the speaker to a constant voltage system, connect the speaker's black cable to the "COM" socket of the amplifier, while the red cable is to be connected to the 100V socket of the amplifier.

If you need to connect several speakers, after checking the total power; you can connect them to the amplifier with a "parallel" connection (Fig.2). Remember to consider the correct section of the cables, according to the distance of the speakers from the amplifier.

Before starting the installation, make sure that the amplifier is off. The voltage present on the connection terminals during operation could be dangerous.

Consider carefully the power of the speakers and of the amplifier where they are connected: the total power of the speakers must not exceed the amplifier's power.

INSTALLATION

Refer to Fig.3 to mount the support plate on the wall (using the included screws and plugs) where the duct with the connection cables is located. To fix the plate correctly, place it against the wall and mark with a pencil the points where the holes will need to be made. Make sure there are no pipes of any kind where you will drill. Proceed by drilling the wall with a tip of the same size of the anchors, then place the plate and secure it by screwing the screws into the plugs. Once the cables have been connected to the bracket, mount the bracket on the wall plate, securing it by means of the screw to be inserted in the upper hole (A).

Important: to avoid the risk of falls make sure that the bracket and the wall plate are correctly mounted and use the supplied safety cable, which is to be fastened to the hole (B) on the back of the speaker and to a screw of the wall plate.

You can now mount the speaker on the bracket as shown in Fig.4. If you wish to detach the speaker from the bracket push down the locking tab (C) and remove the speaker from the bracket.

By loosening the screw (D) you will have the possibility to tilt the speaker in any direction. Tighten again the screw once you have chosen the desired position.
