Frequently Asked Questions - BS 460B Glemm

Can I install the Glemm BS 460B outdoors?

No, this speaker is designed for indoor use only. Exposure to rain or humidity may cause fire or short circuits.

What is the impedance of the speaker?

The speaker has an impedance of 8 Ω, suitable for most PA amplifiers.

Can I connect multiple BS 460B speakers?

Yes, you can connect multiple speakers using series or parallel wiring, ensuring the total impedance remains within the amplifier's supported range (typically 4-16 Ω).

What is the recommended amplifier power?

The total power of the speakers should roughly match the amplifier's power. For a single BS 460B, an amplifier delivering approximately 20-50 W RMS per channel is suitable.

How should I connect the cables?

Insert the '+' and '-' wires into the amplifier's output terminals, respecting polarity. Use an appropriate cable section based on distance from amplifier.

Does the BS 460B come with a warranty?

Yes, it is covered by warranty according to national and European regulations. The warranty requires the original purchase receipt and is void if tampered with or used improperly.

Can I install the speaker myself?

Installation should be carried out exclusively by specialized technicians skilled in electric and audio systems to ensure safety and performance.

What happens if I connect the speaker with wrong impedance?

Wrong impedances can seriously damage the connected fixtures and the amplifier. Always verify the total impedance before connecting.

How do I clean the speaker?

Keep the speaker dry and clean. Use a soft, dry cloth to wipe the surface. Avoid using liquids or aggressive cleaners.

Is the speaker CE certified?

Yes, the CE mark indicates compliance with applicable European directives and harmonized standards.

USER MANUAL BS 460B Glemm

In-wall/ in-ceiling audio speaker operating at 8Ω and intended for Pa system installations. The high quality of the components used for its construction guarantees an excellent audio performance.

The installation of this product must be carried out exclusively by specialized technicians, skilled in electric and audio systems.

In case of wrong installation or connections, the manufacturer doesn't take any responsibility for damages to people or objects.

Refer to the below picture (pict.1) for correct cable connection. Before starting the installation make sure that the amplifier is turned off.

Keep this instruction manual for future reference. This product is not suitable for outdoor use. To avoid the risk of fire or shortcircuits don't expose it to rain or humidity.

Wiring

For connection insert the "+" and the "-" wire into output terminals of the amplifier, respecting the indicated polarities.

If you need to connect more than one speaker, after checking the total power, you have to make series or parallel wiring (see example in pict. 1), to obtain a final impedance supported by the amplifier (usually 4-16Ω).

Wrong impedances can seriously damage the connected fixtures.

Remember to consider the correct section of the cables, according to the distance of the speakers from the amplifier.

Consider carefully the total power of the speakers, which must correspond more or less to the amplifier's power.
