Product Information
Full details
The Citronic P44800 is a 2.1 stereo power amplifier designed for cost-effective and efficient bi-amplified sound systems. It's ideal for users who need to power separate mid-top cabinets and a subwoofer from a single unit, offering a clean and powerful audio solution. A key benefit is its integrated active crossover, simplifying setup. However, its reliance on wired connections and the absence of built-in digital displays might be a consideration for some advanced setups.

FAQs
What is the power output at 8 Ohms?
The amplifier provides 250W RMS per stereo channel and 500W RMS for the subwoofer channel when connected to 8 Ohm loads.
How do I connect my speakers?
Use Speakon (SPK) connectors to connect your passive mid-top speakers to the stereo channel outputs and your passive subwoofer to the dedicated subwoofer output.
Can I use this amplifier for full-range speakers only?
Yes, you can use it for full-range speakers by setting the crossover frequency to its lowest setting or bypassing it if possible, but it is optimized for bi-amplified systems with a subwoofer.
What is the function of the active crossover?
The active crossover routes low frequencies to the subwoofer output and higher frequencies to the stereo outputs, allowing for a more efficient and cleaner sound reproduction when used with separate subwoofers and mid-top cabinets.
What is the Signal-to-Noise Ratio (SNR)?
The Signal-to-Noise Ratio (SNR) is 86 dB, indicating a good level of audio fidelity with minimal background noise.
Does it have a built-in EQ?
No, the P44800 does not feature a built-in equalizer. EQ adjustments should be made using an external mixer or audio processor.
What type of mains plug does it come with?
It is supplied with a UK mains plug (Type G).
Troubleshooting
No sound from any channel
Ensure the amplifier is powered on (check the 'On/Off' switch and mains connection). Verify that all audio source connections are secure and that the input signal is active. Check that channel level controls are not set to minimum.
No sound from subwoofer channel only
Confirm the subwoofer is properly connected to the designated subwoofer SPK output. Check the subwoofer's own power and volume settings. Adjust the crossover frequency to ensure it's set to a range that includes low frequencies. Verify the subwoofer channel level is not at minimum.
Distorted audio output
Reduce the input signal level to the amplifier or lower the channel level controls. Ensure speakers are not overloaded and that impedance matches the amplifier's specifications. Check for damaged speaker cables.
Amplifier turns off unexpectedly
The unit may have activated its protection circuitry due to overheating or a short circuit. Ensure adequate ventilation. Check speaker connections for shorts. Allow the unit to cool down before restarting.
Hum or buzz from speakers
This could be a grounding issue. Try using balanced XLR connections if possible, or ensure all connected equipment shares a common ground. Check for nearby sources of electrical interference.

Setup, Compatibility & Care
Setup:
- Connect your audio source (e.g., mixer, DJ controller) to the 3x XLRF or 3x Jack inputs using appropriate cables.
- Connect your mid-top speaker cabinets to the SPK outputs designated for the stereo channels (Channels 1 & 2).
- Connect your subwoofer to the SPK output designated for the subwoofer channel (Channel 3).
- Adjust the crossover frequency control to match your speaker system's capabilities, typically between 80Hz and 120Hz as a starting point.
- Set the individual channel level controls and connect the included UK mains plug (Type G).
- Turn on the amplifier using the 'On/Off' switch.
Compatibility:
- Speakers: Compatible with passive mid-top speaker cabinets and passive subwoofers requiring up to 400W RMS (stereo) or 800W RMS (sub) at 4 Ohms, or 250W RMS (stereo) / 500W RMS (sub) at 8 Ohms.
- Sources: Works with any line-level audio source providing a balanced or unbalanced signal via XLR or Jack outputs.
Care:
- Ensure adequate ventilation around the amplifier to prevent overheating. Do not block air vents.
- Clean the exterior with a dry or slightly damp cloth. Avoid using abrasive cleaners or solvents.
- Protect the unit from dust, moisture, and extreme temperatures.
- Periodically check all cable connections for security.
