This is the mini Buffer with variable output Impedance and it's suitable for use with a guitar, bass and any other instrument with similar pickups.
A buffer is a circuit where the output is the same as the input. The "secret" is that this particular buffer circuit has a very high input impedance (10Mohm) and variable output impedance (0~220kohm).

Without getting into many details this eventually means that it improves the high frequency response of your overall pedal chain so that you don't lose your tone as your highs aren't getting sucked up.

Additionally, through its single knob you can adjust its output impedance to match the output impedance of your guitar pickups so that any pedal (e.g. a vintage fuzz, or any low input impedance pedal) that comes after the buffer behaves in the same manner as when you connect the guitar directly to it.

A buffer can also help you run long cords without risking losing tone or making your sound bassy and muffled

- Input impedance: 10Mohm (constant)
- Output Impedance: variable 0~220kohm

2in1: Volume Attenuator & Booster (+30dB) housed together in a single enclosure. Both circuits are active.

>>>> Attenuator specifications:
The active circuit consists of an input buffer, a volume attenuator controlled by the potentiometer and an output buffer.
This way it picks up the audio signal without degrading or coloring it no matter how much you attenuate it and passes it intact to a low impedance output.
- Input impedance: 10Mohm
- Output impedance: 100ohm
- Input signal level: up to ~24Vpp

IMPORTANT NOTE: This is a volume attenuator, NOT a power attenuator. Do not use it as a load between a power amp and a speaker.

>>>> Booster specifications:
The active circuit consists of an input buffer (which is also the first boost stage, +6dB) and of a second stage with a variable amount of boost, controlled by the respective potentiometer (+30dB at max).
Again the input impedance is high and the output impedance is low in order to maintain the signal's fidelity and clarity without coloring it.

- Input impedance: 10Mohm
- Output impedance: 100ohm
- Minimum Boost: +6dB
- Maximum Boost: +30dB
- Max input voltage swing: ~7.5Vpp
- Max output voltage swing: ~24Vpp

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 low output impedance ensures the best interconnectivity with the rest of your gear while maintaining your signal's clarity & tone.

- Required supply: 9V (Polarity: negative tip)
- Current draw: 40mA
- Flat response on the whole span of the audio frequency spectrum.

4-way splitter with all four outputs isolated.
This is an active, buffered, 4-way Splitter suitable both for bass & guitar or any other instrument with similar pickups. It features high input impedance and very low output impedance in order to preserve your tone and to not degrade your signal.

Every output is equal to the input (zero volume drop) and is isolated each with a dedicated audio transformer. Each output has a dedicated footswitch (and a LED) so that you can turn them ON/OFF on the fly.

The splitter can be powered with a variery of voltages ranging from 9V up to 18V max. Larger voltages offer you more headroom (DO NOT EXCEED 18V) so that you can also use it for line level signals.

All output jacks, including the DC-jack are placed at the top-side of the enclosure and the input jack on the right side.

▹ Input impedance: 10MΩ
▹ Output impedance: 100Ω
▹ Voltage required: 9-18V DC [Do not exceed recommended voltage! It may damage the circuit.]
▹ Polarity: Center negative
▹ Current consumption: 10mA @ 9V || 15mA @ 18V
▹ Enclosure dimensions: 120 x 95 x 35mm (4.72 x 3.74 x 1.37in)
▹ Weight: 435gr
