MAYA, most advanced volume controller in the world

Now available in our webshop.

OEM MANUFACTURERS ARE WELCOME – We will work with you to make MAYA part of your product.

Looking for state of the art volume controller for your product ?
You are on the right place.
Maya is a 64 step R-2R ladder volume controller designed as your ultimate solution in input selection and attenuation.
This attenuator provides 64 positions ranging from 0 to -63dB with average stepsizes of 1dB.
Mute at >130dB.  Left and Right channels completely isolated with separate grounds, ideal for dual mono approach.
Input resistance ranges from 16.37k up to Rload . Where Rload = your pre/amplifier input impedance.
Constant output resistance 10K.
IN - OUT complete passive R-2R resistive network with zero active parts, make from this attenuator an ideal solution when it comes to no compromise audiophile equipment. The high-quality Takamisawa relays and Melf resistors provide superb audio quality which is maintained over a very long lifetime.

    - R-2R 64 1dB step attenuation
    - IOS or Android client for bluetooth remote control
    - infrared remote RC5 protocol with autolearning
    - infrared remote NEC protocol for Apple remote (default)
    - OLED display
    - 4 selectable inputs
    - independent volume control for each input - very good for A-B source comparison
    - extra low noise ground separation between digital and analog circuitry
    - inrush current protection
    - soft start with speaker protection
    - soft turn off with speaker protection
    - plate voltage delay for tube pre/amplifiers
    - temperature display and monitoring
    - temperature protection
    - serial I2C bus for unlimited channel extension
    - easy direct control and setup with precision optical encoder

Maya offer two solutions for remote controll: Bluetooth via dedicated IOS or Android application and Infrared tough autolearning NEC and RC5 protocols.
