Outboard Audio Processing
Whilst not in pursuit of ESSB, I am trying to maximise my 3Khz transmit bandwidth with audio processing. I have chosen equipment based on performance as well as keeping the item count down to minimise the potential for RF pick-up into the audio. Starting with the Aphex Channel, which is widely regarded in the studio arena for vocal audio processing, using the Aphex patented Aural Exciter and Big Bottom. Additionally, the tube Pre-amp and Phantom Power provide a good base for the Rode NT-2A Condenser Microphone.
A Behringer QX1002USB Mixer provides level control and the ability to add effects to the audio stream, having Klark Teknik Multi-FX Processor on-board and a manual 3 band EQ for audio tailoring of other audio sources.
For Receive, a set of JBL Control 2P Active Studio Monitors, as recommended by Bob Heil are connected to a Nobsound switch to enable switching between the Radios, and has been modified with a tap to feed the Shack PC Line In for on-air recording. Recorded audio can be sent back over the air from the USB line in, into the mixer. An optional patch is provided to line-in for the Sonos System.
Next Purchase will be a TC Electronic DBMax, or Omnia/Orban Processor if I can find one.
