1. What is the total power output of this amplifier system?
The amplifier is rated at 40W. This refers to the unit's rated power output used to drive the connected speakers.
2. Does the amplifier support Bluetooth and how do I pair a device?
Yes — it is an active Bluetooth amplifier. To pair, enable Bluetooth on your phone or source device, set the amplifier to Bluetooth mode (using the front panel or remote), then select the amplifier from your device's Bluetooth list. Follow on-screen prompts if required.
3. What speaker types and impedances are supported?
The amplifier supports both constant-voltage distributed speaker systems (70–100V) and low-impedance speakers (4–16 Ω). Use the transformer outputs for 70–100V lines or the standard outputs for 4–16 Ω speakers.
4. What is included in the package?
The package includes the active Bluetooth amplifier and four ceiling speakers, packaged in a box/carton. For exact accessory list (cables, screws, manuals), check the seller's product listing or contact the supplier.
5. What audio inputs and outputs are available?
Inputs: Bluetooth, a plug-and-play USB disk port, FM radio tuner, one auxiliary (AUX) input and two microphone inputs. Output: one auxiliary output for linking to another amplifier or device.
6. Are there microphone controls and how many mics can I connect?
Yes — the unit has two microphone inputs. The system provides individual volume control along with low and high tone controls to adjust microphone sound.
7. Does the amplifier have a remote control?
Yes, the amplifier comes with a wireless remote control for selecting sources and adjusting volume and playback (functions may vary by remote model).
8. What protection features does the amplifier include?
Built-in protections include short-circuit protection, over-temperature protection, over-load protection, and an alarm function to alert you to fault conditions.
9. What is the 70–100V output used for?
The 70–100V (constant-voltage) output is used for distributed speaker systems where many speakers are connected across long cable runs, common in PA, commercial, and multi-room installations. It allows easier parallel wiring without complex impedance calculations.
10. How do I wire multiple ceiling speakers to the 70V output?
Use each speaker's matching tap or transformer setting to set wattage for the 70V line and wire them in parallel to the amplifier's 70–100V output. Ensure the total wattage does not exceed the amplifier's rated capacity (40W). Refer to the speaker manual or a professional installer for exact tap settings.
11. What is the LED level meter for?
The five-element LED level meter provides quick visual monitoring of the output level so you can see signal strength and avoid clipping.
12. Is there tone control or EQ on the unit?
Yes — the amplifier offers low and high tone controls to adjust bass and treble for the overall sound and microphone channels.
13. Can the amplifier mute audio remotely or automatically?
The unit is compatible with a muting function. Depending on the model/remote, you can mute audio via the remote or by using the front-panel controls.
14. Are there installation or safety recommendations?
Install the amplifier in a well-ventilated area away from moisture and heat sources. Do not block ventilation slots. For ceiling speakers, follow proper mounting guidelines, cutout sizes, and wiring best practices. If unsure, hire a qualified installer.
15. What about warranty and technical support?
Warranty and support details are not specified in the product description. Contact the seller or manufacturer for warranty terms, service procedures, and after-sales support.
