Frequently asked questions
What is each product designed to do?
The ASU4000 distributes 8V DC power to antenna elements in UHF wireless microphone systems (500–865 MHz). The HP4E amplifies audio signals and sends them to four headphone outputs independently, suited for live monitoring and studio cueing.
Are these products compatible with each other?
No. The ASU4000 handles RF antenna power for wireless mics; the HP4E handles audio-frequency headphone amplification. They serve entirely different functions and operate on different signal types.
Which one is more portable for touring?
Both are compact and lightweight, but the ASU4000 (150 g, waterproof metal) is built specifically for harsh outdoor and vehicle environments, whereas the HP4E (760 g, half-rack format) is optimized for studio and monitor console setups with occasional field use.
Do I need both of these if I run a wireless mic system?
Not necessarily. The ASU4000 powers your wireless antenna elements; the HP4E is useful only if you also need to send independent headphone mixes to performers or monitor engineers—they solve unrelated problems.
