Manley VOXBOX Class A Microphone Preamplifier
Manley VOXBOX Class A Microphone Preamplifier
The VOXBOX® combines the legendary Manley Mono Mic Preamp, the ELOP reborn as a lower ratio compressor, the MID EQ blown out as a full range PEAK-DIP-PEAK EQ, and a DeEsser with a second ELOP limiter at the end. Using the Direct Input, bass players often wonder why it wasn’t named the BASSBOX.

Operating Mains Votage:
- Units are purpose built for original destination country’s mains voltage: 100V, 120V, or 220-240VAC as indicated on the serial number badge. Power transformer must be replaced in order to change mains operating voltage.
- 120VAC units may NOT be rewired to put the primaries of the power transformer in series for 220-240V operation or a large radiated field of hum will develop. If changing locations/voltages, the power transformer must be replaced with the dedicated one for the voltage at which it will operate and the mains fuse must be changed.
- Mains Fuse Value for 120VAC = 1 Amp Slo-Blo 1/4” x 1 1/4”
- Mains Fuse Value for 240VAC= 1/2 Amp Slo-Blo 1/4” x 1 1/4”
