PreMax™ FAQ

If you don't see the question you had in mind here, feel free to enter it in the form provided along with your email address so we can send the reply directly to you. Thanks for your participation!

How does the PreMax compare to the PowerPre™?

The PowerPre is a 100% discrete preamp. In other words, it employs individual resistors, capacitors and transistors to amplify the signal. This of course is the ultimate method of building a solid state preamp. But given the limited space inside a 500 series module, there is no way that we could jam a preamp and an EQ into such a small footprint. The PreMax is more of a high-tech alternative that employs integrated Op-Amps to accomplish the goal.

Can I use the PreMax to record all instruments?

Yes. Although the instrument input impedance is optimized for magnetic pickups, instruments with built-in active electronics will work equally well. This includes active basses, keyboards, guitars and so on.

Can I use the PreMax as a bass preamp?

Absolutely. Combine the PreMax with a Komit compressor and a JDX speaker simulator. Slot the modules into a PowerStrip and you are now ready to rock the Casbah.

Why is the phantom power switch recessed?

There are two reasons for this. While most microphones can be safely used when phantom power is on, some older ribbon microphones can be damaged by the DC voltage. Making the 48V phantom switch hard to accidentally turn on provides you with an extra measure of safety. Secondly, turning the phantom power on when your audio levels are up will send a loud pop to your speakers which could blow the tweeter.

Will the PreMax fit in all 500 series racks?

Yes. It has been tested to fit inside racks made by API and Purple.

How do I access the Omniport function with my old API rack?

Alas, you cannot. We invented the Omniport function when developing the Radial Workhorse and this innovation has yet to be implemented by API into their racks.

Is Radial part of the VPR Alliance?

Although Radial is not a member of the VPR alliance, we have been careful to ensure our modules follow the original API specification so that the PreMax can safely be used in VPR approved racks.

Why is Radial not a member of the VPR Alliance?

API chose to not admit Radial into their alliance for two reasons. One, we make 500 series power racks which means we compete directly with them and two, VPR modules must retail for $700 or more. As we make many lower priced modules, we believe that API is concerned that we will erode their profitability.

Is it possible to bypass the preamp with line level signal and go directly into the EQ?

No, the preamplifier is always in the chain. The EQ is not intended to be used with a different mic pre.
