2in1: a volume Attenuator and a Booster housed together in a single enclosure. Both circuits are active & piezo compatible
*** Attenuator Specifications ***
The attenuator features an input buffer, a potentiometer-controlled active attenuation stage, and an output buffer. This design preserves signal integrity and prevents tone loss or coloration, regardless of the amount of attenuation, while providing a low-impedance output.
▹ Input impedance: 10MΩ
▹ Output impedance: 100Ω
▹ Maximum input signal level: ~24 Vpp
Important: This is a volume attenuator, not a power attenuator. Do not place it between a power amplifier and a speaker.
▹ Input impedance: 10MΩ
▹ Output impedance: 100Ω
▹ Maximum input signal level: ~24 Vpp

*** Booster Specifications ***
The booster contains an input buffer (which also provides the first gain stage at +6 dB) followed by a second gain stage with variable boost, controlled via the potentiometer (up to approximately +30dB at max). High input impedance and low output impedance ensure maximum signal clarity without unwanted coloration.
▹ Input impedance: 10MΩ (suitable for piezo pickups as well)
▹ Output impedance: 100Ω
▹ Minimum boost: +6dB
▹ Maximum boost: +30dB
▹ Maximum input voltage swing: ~7.5 Vpp
▹ Maximum output voltage swing: ~24 Vpp
▹ Input impedance: 10MΩ (suitable for piezo pickups as well)
▹ Output impedance: 100Ω
▹ Minimum boost: +6dB
▹ Maximum boost: +30dB
▹ Maximum input voltage swing: ~7.5 Vpp
▹ Maximum output voltage swing: ~24 Vpp
------------------------
The device works with 9V power supply. However, a dedicated internal module converts the 9V single supply to dual rail voltage supply (+15,0,-15) in order to properly power the internal ICs for both the attenuator and the booster and provide maximum stability and headroom.
The high input impedance of both circuits combined with the very low output impedance ensures the best inter-connectivity with the rest of your gear while maintaining your signal's clarity & tone.
- Required supply: 9V (Polarity: negative tip)
- Current draw: 40mA
