Glasshouse Elma A47 Jumbo Stepped Attenuator, Shunt Mono version, 47 steps

The A47 switch from Elma, suitably called the JUMBO, in combination with various 0.5W and 1W resistors, you choose which you prefer. We collaborated closely with Elma to create the JUMBO PCB that fits snugly on the A47 switch. The board accommodates 0.5W and 1W resistors in an easy-to-construct format, with each step clearly numbered on the PCB.

Available in a kit form, we provide 46 labelled bags corresponding to the resistor numbers on the board. You populate the board using the Mundorf 3.8% silver/gold solder provided in the kit. Each resistor position is clearly labelled on the thick PCB, as are the input, output, and ground connections. For those who wish, we can supply fully built and tested for an additional charge of £25.00 + vat. The MONO version does not require you to take the switch apart. We also offer the stereo version of this step.

You have the choice of the 0.5W and 1W versions of the PRP PR9372 series, the Takman carbon films (musical and detailed), and the Takman 1W metal films (dynamic sound with superb sound staging) If you want to choose a different Series (load) resistor such as the exquisite Charcroft then these need to purchased separately.

This is a seriously high-end solution for your stepped attenuator, offering stunning performance and low noise and giving you a real quality feel when turning. Also, you can make your stepped remote-controlled by combining this with the Elma Remote Audio PLUS with LIN Motor
