Radio Studio Equipment for Sale

A few broadcast delights that are for sale – anything listed here is still available.
Smaller items (not the mixers) I am happy to post/courier (UK only) – the mixers are collection-only, but can be delivered within this area for the full asking price, I will not post them.  I also visit family in Essex semi-regularly, so if you’re near the Newark-A1-A14-M11-Stansted-Chelmsford route then we can work something out.


Eela S340 “split” Mixing Console – £700 (subject to delivery/collection arrangements, see top of this page)
This S340 was originally installed at Century 105 in Salford and was the main on-air desk that appeared in the “Trouble at the Top” documentary featuring the late John Myers.

Eela S340 Split Mixing Console

Dating from mid-1998, this desk works fine although has some age-related marks and a few of the PFL buttons are a little “scratchy”. The Mic Gain trimmers are also a little crackly. Faders (P&G) are VCA, the main On/Off/Start buttons are EAO Series and last forever.

The desk has been deep-cleaned and is now rather shiny with some new P&G fader-knobs.

This is a split-desk comprising 2x 12-channel frames – 1 of which contains the meter-bridge and additional connections at the rear. As such, it is considerably heavy and just about OK for 1 person to carry whilst the other frame is quite manageable.  The frames are 19″/485mm wide (40mm per module).  The main chassis can be used on its own if you just want a small robust mixer with a spare set chassis+channel modules “just in case”.

A ring-binder manual of information, circuit diagrams and configuration settings is provided which allows you to easily service (and fault-find) the desk. Here is a ZIP file containing several photos from the manual, plus other assorted information.

Eela S340 Split Mixing ConsoleMost parts are still obtainable: Faders (10k linear), op-amps (NE5532, TL082/084). I have replaced some of the electrolytic capacitors and a few op-amps which either failed or didn’t meet spec when tested.  Unlike “modern” IP desks, the use of discrete (and easily removed) components makes the usual maintenance fairly easy.

2x 12-channel Frames (right-side contains meter-bridge+wiring)
4x S341 Mic/Mic (EQ)
9x S342 Stereo
1x S342 Stereo (EQ)
1x S343 Telco/OS
4x S343 Telco/OS (EQ)
12-way Selector
2x Blank Modules
3U PSU (inc connecting cable)
Full Technical Manual (circuit diagrams, config etc)

The 2 channels on the far left (S342/EQ+S343) are spare and have no rear connector panel.  Modules can be moved around so virtually any layout can be created with the aid of a screwdriver.  Remote-start of machines plus return tallies (ie: play lamp), full remote “Mic” control (on/off, cough/PFL-TalkBack) and an off-air record function (leaving playout faders routed to “Air”) all add to the useful functions offered.

The timer module is not wired in; this module replaced the hole left by the old OS Selector that was removed before I got the desk.  You could place your own custom switch panel here and run the wires out the back.  The 12-way Selector has a stereo output that usually routes to the EXT1 or EXT2 monitor input allowing you to listen to a variety of feeds/sources in the studio – but you could feed it to a stereo channel as a multi-input remote-source selector.  Very flexible!

Connectors to the stereo channels are on 25-way Sub-D, XLR on the Mics and other Sub-D (9, 15, 25) connectors for Output, Switching, Talkback etc.  Some 25-way/Phono-socket “breakout” looms plus a selection of spare op-amp chips will be included.


Soundcraft RM105 8-channel Mixing Desk – £350 (subject to delivery/collection arrangements, see top of this page)
Soundcraft RM105 Broadcast MixerThis would make a neat newsroom or production mixer at a Community Radio Station with its ease of use and small footprint.  It may also be handy in a bedroom studio, for recording shows, podcasts or Skype/Zoom calls.

The 2 telco modules allow for connection to both a phone (POTS) hybrid plus a computer for VoIP/Zoom – each having their own clean-feed and off-air talkback during PFL.

Coarse level-trimmers allow for setting-up a module to a nominal operating level with +/- 15dB Gain trim for day-to-day adjustments.

A post-fade Aux Send creates an additional clean-feed (handy if you require a stereo CF to a remote-studio), a “microphone-only” feed or effects send.  Remote-start, on-air signalling, 4 external monitor inputs and PPM monitoring make this a small yet powerful bit of alright.

The operating manual (featuring details of connections and mixer operation) can be found here.

1x Mic/Line (EQ)
2x Mic/Line
3x Stereo (EQ)
2x Telco (EQ)
Master Section (3-modules wide) – this is the Mk1 version, no Guest H/P output
Power-supply (free-standing, not rack) with link cable to mixer – just add a “kettle” lead.

The image above is missing the screws holding the Meter-Bridge panel, they are included but my best picture was taken during alignment of the PPM driver board.

P&G FadersThis desk has had a thorough clean in all of its special places, the faders (P&G) have been re-lubed making them almost box-fresh.  Replacement faders are 10k mono, linear and will require a switch (Digikey part# 255-3743-ND).  You could also use Alps, but the switch is necessary (D&R webshop sell them here).

Some minor scratchy Gain pots although these are hardly noticeable if the audio is loud enough.  Faders are VCA, so no crackles there.  There are a few minor blemishes on the chassis but nothing too drastic.

Channels have been labelled for a typical environment but you can easily make your own – the modules can be moved around if you’d prefer a different layout.

The desk can sit directly on a table-top or be mounted several ways into a cut-out, either semi-flush or flat (the manual has pictures of this).

Optional, if you need them:

  • 4x White Sifam fader-knobs
  • 3x 3.5mm to left/right XLR “soundcard” cables
  • External Input 1+2 Connector with short trailing phono sockets (to route “off-air” and/or a post-processor feed back to your cans/speakers)

4MB Extra Density Floppy Disks20x 4MB Extra Density Floppy Disks – £30 inc UK Postage
These are 2.88MB / 4MB ED disks and I have 2 unopened packs of 10, so “new old stock” (bought around 2005).

Useful if you have a Sonfiex Discart machine – they hold 81-seconds of stereo 44.1KHz audio vs 36-sec from a conventional (1.44MB/2MB) disk.

My own (well used) disks were recently dubbed into the computer and played without issues so I reckon these will be fine.

The main drive manufacturers, Mitsumi/Sony, ceased production in 1999…Rare as rocking-horse doo-doo, as they say.


Outer Ring (3D-printed plastic) for TC Electronic Processor – £8 inc UK Postage
This replaces the often forgotten/lost outer ring jog-dial on several TC Electronic processors (like the Triple C).  The 3D-print files for both the inner+outer jog-wheel are easily found online but unless you have a local “maker” facility willing to do it for pocket-money, you may be subject to a minimum order with many of the “upload+print” online services.

Just remove the inner knob gently, then place the outer ring onto the moulded notches, and replace the inner – simples.

USB Fader-Start Joystick Interface – £55 inc UK Postage
This is the previous version of the interface box which used a Joystick controller and works with a number of playout systems, including Myriad 4*, mAirList, DAC Cartwall plus StudioScreen and FreePlayer.  Fully working, just new-old-stock and includes 1m USB “A to B” cable (like a printer).

*For reasons unknown, the “joystick” device is NOT recognised by Broadcast Radio’s Myriad v5/v6 “Hardware Service”.

1 Joystick (shown below) unit remaining – inputs are defined via the software, so the “action” performed can be changed whenever you wish.

USB Fader-Start Joystick/Keyboard Interface

Details of my current USB/RS232 Interface, fully compatible with multiple studio applications, can be found on this page.


USB Remote-Start InterfaceUSB Remote-Start Joystick Interface, basic version – £45 inc UK Postage
This is a 6-input fader/remote-start “joystick” interface – Same internal device as my metal “joystick” model but in a “domestic” plastic enclosure with only 6 inputs.

TWO UNITS AVAILABLE

These are recently-built units made from spares left from the Mk2 design.  The Mk1 was a black square plastic box and the Mk3 is the aluminium type.  I still use 2 of these in my studio: 1 for Playout and the other handles LED “On-Air” displays and coloured RGB strip-lights, they sit on the computer shelf, run 24/7 and are largely forgotten about.

Can be used with DAC Cartwall, mAirList, Myriad v4*, StudioScreen and other applications that feature control via a game/joystick device.

*For reasons unknown, the “joystick” device is NOT recognised by Broadcast Radio’s Myriad v5/v6 “Hardware Service”.

Ideal for remote-start of Player Decks in automation software or for toggling LEDs in my StudioScreen clock display.

A 1m USB cable is included – as a “joystick” device, it’s plug’n’play, no driver required.
