Frequently Asked Questions - PreComp Radial Engineering
What is the Radial Engineering PreComp?
The PreComp is a professional stereo compressor/limiter designed for studio, live, and broadcast applications. It offers transparent gain reduction with comprehensive controls.
How do I connect the PreComp to my mixer?
Use balanced XLR or TRS cables. Connect the output of your mixer to the inputs of the PreComp, then connect the outputs to your next device (e.g., equalizer, crossover).
What is the power requirement for the PreComp?
The unit has an internal universal power supply that accepts 100-240 VAC, 50/60 Hz. No external transformer is needed.
Can I use the PreComp on a single channel?
Yes, you can use either channel independently. Each channel has its own controls, and the stereo-link switch couples both channels for stereo operation.
What do the attack and release controls do?
Attack controls how quickly the compressor responds to signals above the threshold (from 0.1 ms to 50 ms). Release sets how fast it recovers (from 50 ms to 1.5 s). These shape the dynamic envelope.
How do I set the threshold and ratio?
Start with a low ratio (2:1) and lower the threshold until you see gain reduction of 3-6 dB on peaks. Adjust the ratio higher (up to 20:1) for limiting.
What is the makeup gain for?
Compression reduces overall level. Use makeup gain (up to +20 dB) to restore the output level to match the input.
How do I clean and maintain the PreComp?
Disconnect from power, then wipe the front panel and chassis with a soft dry cloth. Avoid liquids, sprays, and abrasive cleaners. Keep vents unobstructed.
Is the PreComp safe for rack installation?
Yes, it is designed for standard 19-inch racks. Allow 1U of space and ensure adequate ventilation. Use rack screws to secure it firmly.
What should I do if the unit does not power on?
Check the power cord, wall outlet, and the rear panel fuse. If the fuse is blown, replace it with the same rating. If the problem persists, contact Radial support.
