Frequently Asked Questions - HXM800.1D Diamond Audio
What is the recommended impedance for the Diamond Audio HXM800.1D?
The amplifier is stable down to 1 ohm. For optimal performance, it delivers 300W at 4 ohms, 500W at 2 ohms, and 800W at 1 ohm.
How do I set the low-pass filter on this amplifier?
Use the Low Pass Filter control to adjust the cutoff frequency between 40 Hz and 250 Hz. Set it according to your subwoofer's frequency range, typically around 80-120 Hz for most systems.
What type of power connection does the HXM800.1D require?
It requires a 12V DC power source (10-16V), typically from your car battery. Use a 60A fuse and appropriate gauge wiring for the current draw.
Can the amplifier be bridged?
The HXM800.1D is a monoblock amplifier, meaning it has a single channel. It is already designed to drive one subwoofer or a bank of subwoofers wired together.
How do I wire the remote turn-on connection?
Connect the REM terminal to the turn-on lead from your head unit or an ignition-switched 12V source. This enables the amplifier to power on and off with the system.
What is the subsonic filter used for?
The subsonic filter removes ultra-low frequencies below the audible range (20-80 Hz). It protects your subwoofer from excessive cone excursion caused by infrasonic signals.
Why does the amplifier shut down unexpectedly?
This may indicate thermal overload, short circuit, or low impedance. Check the speaker wiring for shorts, ensure proper ventilation, and verify that the impedance is not below 1 ohm.
What maintenance does the amplifier require?
Regularly wipe the exterior with a dry cloth to remove dust and debris. Avoid using liquids or solvents, as they may damage the internals.
Is the HXM800.1D suitable for powering a full-range speaker?
This amplifier is specifically designed for subwoofer applications. It has a low-pass filter and is optimized for low-frequency reproduction, not full-range speakers.
What should I do if I need spare parts or service?
The amplifier is not user-serviceable. For any repair or part replacement, contact Diamond Audio authorized service centers or your local dealer for professional assistance.
