Frequently Asked Questions - SubMix Radial Engineering
How do I connect my main speakers and subwoofer to the SubMix?
Connect the full-range signal from your mixer or preamp to the INPUT jacks. Then connect your main speakers to the MAIN OUTPUT and your subwoofer to the SUB OUTPUT. Adjust the CROSSOVER frequency to blend the units.
What is the purpose of the Ground Lift switch?
The Ground Lift switch disconnects pin 1 (ground) from the chassis to break ground loops that cause hum and buzz. Start with the switch in the 'Lift' position if you hear hum.
Can I power the SubMix from a pedalboard power supply?
Yes, the SubMix accepts a standard 9V DC supply at 500 mA. Use a regulated power supply with a 2.1mm barrel connector (center negative).
What type of cables should I use?
Use balanced XLR cables for best noise rejection. Unbalanced cables may work but can introduce noise over longer distances.
How do I set the crossover frequency?
Start with the CROSSOVER control set to 80 Hz (common THX standard). Adjust up or down to match your subwoofer and main speakers for a seamless transition.
What does the Phase switch do?
The Phase switch inverts the polarity of the subwoofer output by 180 degrees. Use it to align the subwoofer's sound wave with the main speakers for better bass integration.
My subwoofer sounds boomy or disconnected. What should I check?
First, verify the LEVEL control isn't too high. Next, adjust the CROSSOVER frequency and try the PHASE switch in both positions. Ensure all cables are fully inserted and not faulty.
Is the SubMix compatible with high-level (speaker) inputs?
No, the SubMix is designed for line-level signals only. Do not connect speaker outputs to its inputs; it may cause damage.
How do I clean the SubMix?
Disconnect power and use a dry, soft cloth to wipe the chassis. For stubborn spots, slightly dampen the cloth with water. Do not use solvents or abrasive cleaners.
What is the warranty period for the Radial SubMix?
Radial Engineering offers a 3-year transferable warranty. Register your product on the Radial website to activate coverage.
