Oaka Instruments Stereo Pre Portable Mic Preamp

A stereo, low noise and battery operated portable pre-amp designed to power and amplify Oaka Instruments microphones. The Stereo Pre has been created to expand the possibilities of field recording and sampling, acting as an interface between microphones and hardware which feature line level inputs, like modular synthesisers or other physical sampling equipment.

• Two independent low noise pre-amps
• 200hz Low Cut Filter on each channel
• Independent gain control on each channel
• x2 female XLR Inputs & x2 1/4inch Jack outputs
• 9-12v DC operation from either battery or DC input (lasts 4 hours ‍continuous use from 9v rechargeable battery)
• All metal, durable enclosure designed and machined in house

Please note: this pre-amp provides continuous 15v power to microphones and will work on all Oaka Microphones, in theory the Stereo Pre will work with most small microphones which require phantom power. I will do my best to test the pre-amp on as many microphones as I can and provide a list of all compatible microphones.

The pre-amp circuit is based on a design by Jules Ryckebusch and kindly adapted with his permission.
