Symetrix 528E Voice Processor

Although we call the Symetrix 528E a "Voice Processor," it is perfectly suitable for any mic- or line-level source. The 528E works with any professional microphone. Mic preamp gain is variable up to 60 dB, and 48 volt phantom power is provided for condenser mics. A switchable 15 dB pad reduces gain in front of the mic preamp to prevent distortion in super-close micing situations. A front panel switch selects between microphone or line input. Both inputs are transformerless and are equipped with filters to prevent radio frequency interference (RFI).

Get the same processing power found in an entire recording studio signal chain with the 528E Voice Processor from Symetrix, the engineering-driven company of signal processing specialists.
