It's becoming more and more common for live sound engineers to use outboard mic preamps on specific sources like lead vocals, acoustic guitars, snare drums and more. Especially built for those engineers who have to use a different PA system every night at different venues. This allows them to keep a consistent sound for their featured instruments.
Professional Studio Recording-
The A PRE 500 has a very neutral, yet bright character. It sounds exceptionally good on drums and percussion, B3 Organs, electric pianos, and acoustic guitars. The 1/4 inch input makes it easy to run instruments through the mic pre without using a direct box.
The A PRE 500 is approved by the VPR Alliance.
