--- Stereo Preamp / Clean Signal Booster +30dB, with headphone capability and zero hiss ---

This version of our Stereo Preamp/Booster incorporates ultra-low-noise IC technology and provides headphone capability with an exceptionally low noise floor and zero hiss.

The Stereo Preamp can handle Instrument Level signals and Line Level signals as well. It can also take an instrument level signal and boost it up to line level, and even further. You can use it for your pedal board, for sending your audio signal to recording devices, for home audio recordings and for general audio applications where you need to improve the signal to noise ratio (SNR) of your audio.

The ultra low noise ICs at the core of the preamp ensure zero hiss generation and audio grade THD. The high input impedance (1Mohm) combined with the very low output impedance (100ohm) ensures the best inter-connectivity with the rest of your gear while maintaining your signal's clarity & tone.

The input/output knobs act as 'attenuators'. and when they are set at their mininum the mute the signal. The boost knob ranges from 0dB (min) up to +30dB (max).

NOTE FOR THIS VERSION: Compared to our older model, this version uses even higher-grade ICs that deliver professional-level noise performance while also providing sufficient output power to drive a pair of headphones connected to the output.

If you want to connect headphones to the output, make sure to keep the Output knob at its maximum position and adjust the listening volume using the Input knob. If additional volume is required, you can increase it using the Gain knob.

Specifications:

• Input impedance: 1MΩ
• Output impedance: 100Ω
• Boost level: up to +30dB [ = voltage gain when the device is used as a signal booster]
• Max input voltage swing: ~8.5Vpp (Input/Output knobs at max. Boost at min.)
• Max output voltage swing: ~34Vpp
• Standard TRS jacks (6.35mm, 1/4")
• Supply required: 9V DC (negative tip)
• A dedicated internal circuit takes the 9V supply and converts it to dual rail supply (+17V, 0, -17V) in order to provide the maximum possible headroom.
• Current draw: 30-50 mA
• RF filters at the input prevent any unwanted wireless interference (e.g. radio signals etc) from entering to the audio path.
• Enclosure dimensions: 121 x 65 x 39 mm (4.76 x 2.56 x 1.53 in)
• Weight: 250gr

(If you need any slight modifications to the specs listed above let me know.)
