1. BBT-W01: Convert any wired microphone to wireless operation!

£275.00  £199.99

Yes you can!  With the BBT-W01 you can convert any microphone you already own to work wirelessly in the 2.4 GHz Wi-Fi band.  Now you can use your favourite, faithful, trusty wired mic but with the freedom of wireless operation, in the worldwide legal 2.4G band.

Instead of plugging mic cables into the bottom of your mics, simply plug each transmitter into the XLR socket (even condenser mics needing 48V phantom power), and your digital, full frequency CD quality signal is sent to the receiver.

18 frequencies are available, and syncing is easy.  The transmitters use re-chargeable batteries.


  • Dual channel receiver design
  • 18 operating frequencies
  • Sync features for quick pairing of transmitters and receiver
  • +48V phantom power compatible with ON/OFF switch
  • Individuals volume controls on each transmitter
  • Individual 1/4″ outputs
  • Each receiver runs on 2 AA rechargeable batteries (included)

2. 100mm Faders (Sliders)


From our days as a mixer manufacturer, we have a quantity of very good quality mono 100mm faders (sliders) for sale.  These are copies of the Alps fader design, with the control finger running on a lubricated rail or spindle, giving ultra-smooth operation.

Perfect for replacing noisy or intermittent faders on both audio and lighting consoles, the price is a very modest £2.25 plus VAT (no VAT outside the EU or with a valid VAT number), plus postage/carriage.
They are packed in fitted plastic trays of 16 pieces, with 3 trays per box, so please order in multiples of 16 (or boxes of 48).

100mm fader

The nominal value is ‘A10K’ Logarithmic.  Please note we do not have any Linear versions, which would be what is needed for MIDI control applications. The fixing centres are 120mm apart, fixing screws and knobs are not supplied.

Among many other mixers, these are a direct replacement for the Peavey AMR (Audio Media Research) range including 800, the 1600, and the 2400 models, and should work in the Peavey Mark VIII line.  Also Allen & Heath GL2000 and, with minor modifications, the Hill Multimix. Our grateful thanks to Johan Sorscha from Holland, who has written a superb step-by-step guide with photographs on how to upgrade a Hill Multimix with these faders. Download HERE

Ex-demonstration, these are as new, all 19″ 1u high, and there is only 1 of each:

Switchable in/out level metering and gain reduction meter. Sidechain inserts, balanced in and out on XLR and jacks.  Each channel of the DDP-1 features, a Noise Gate; a variable ratio Compressor ranging from 1:1 to infinity:1; and an independent Peak Limiter following ARX DDP-1 compressor/limiterafter the Output Gain.
