Rupert Neve 517 500 Series Mic Preamp/DI/Compressor

The 517 Mic Preamp / DI / Compressor from Rupert Neve provides a world-class transformer-coupled mic preamplifier, one-knob compression, DI circuitry with Vari-phase, Silk saturation and DI + mic blending capabilities – all in a single module.

Rupert Neve 517 Mic Preamp Features

• 12-way precision rotary switch covering from Line (0) and Mic from 0 to 66 dB in 6 dB steps.
• Push button inverts the polarity of the signal path. The symbol “Ø” is often used to denote opposite polarity.
• The VARI-PHASE control rotates the phase incrementally, allowing two signals with the same source to be phase aligned.
• Front panel TRS Input and passive through for hi-z sources. Continuous gain control from 0dB to 30dB.
• THRU & INST 1/4” phone jacks.
