SUNRISE Preamp/ Buffer box
Model SB-1 (Mono)
The Sunrise Preamp Buffer Box is a line matching device designed specifically to access the coupling feature built into Sunrise Pickups.The output of a Sunrise Pickup should be sent first to this preamp.
Sunrise Preamp Buffer Boxes provide the pickup signal with 12dB of gain, high resolution, and impedance matching capabilities. The active 18 volt Bi-Polar powered circuit eliminates pickup loading and line loss due to long cable runs, and also delivers up to 4 years of battery life with 2) 9 volt Energizer Alkaline batteries.
The S-B1 has two 1/4" parallel output jacks (Sunrise and Aux) which allows the same signal to be sent to two separate sources.
The S-B1 produces the widest frequency response possible from a battery powered preamp, and allows the Sunrise Pickup to operate at it's full design capabilities.
