DAR 18 XLR/BNC Addon
£22.00 Ex. VATInput addon to DAR 18 S/PDIF receiver, adding XLR AES/EBU and BNC inputs.
Connectors and headers are included, and you can choose to get them soldered down or not. Note that the XLR in the main photo is full black but currently the connectors we sell have the light metal colour outer casing shown in the second photo.
The addon connects to DAR 18 via three headers. The mating is tight and caution is needed not to bend the headers if addon needs to be removed.

Power Cable 2-Pin
£2.70 Ex. VAT2-pin power cable used in Kaamos Tech digital-only boards.
Use with Kaamos Tech power supplies (coming later) as is or cut the cable and solder to your own power supplies.
This is a standard Molex Micro-Fit 3.0 cable.
-
Power Cable 6-Pin
£4.70 Ex. VAT6-pin power cable used in Kaamos Tech DACs and ADCs.
Use with Kaamos Tech power supplies (coming later) as is or cut the cable and solder to your own power supplies.
This is a standard Molex Micro-Fit 3.0 cable.
Note that the 6P cable is quite stiff and doesn’t bend sharply near the connectors so with 150mm cable the boards need to be very close to one another.
If doing any mods or your own boards, please note that the pinout is mirrored. Therefore, power supply end and target end need to have mirrored footprints. This is irrelevant if using existing Kaamos Tech boards.

SPDIF TX v2
£59.00 – £69.00 Ex. VATPCM I2S to S/PDIF digital audio converter with I2S serial audio input and BNC, Toslink, and AES/EBU outputs.
Product options:
- Channel configuration:
- Dual Mono for 2x ADC AK5572 Mono boards.
- Stereo for any other use.
- Oscillator circuit (soldering included):
- Most use cases are I2S Slave using existing MCLK from the I2S source, not needing this circuit.
- See full product description below and SPDIF TX guide.
- “Yes, with U.FL input”
- U.FL input and three buffered U.FL outputs to split and buffer existing MCLK.
- “Yes, with standard 24.576MHz OSC”
- Connor Winfield 24.576MHz or similar oscillator and three buffered U.FL outputs.
- “Yes, without source (use your own or buy CCHD)”
- Three buffered U.FL outputs but no oscillator. Use your own (check footprint!) or buy Crystek CCHD-957 from us.
- Most use cases are I2S Slave using existing MCLK from the I2S source, not needing this circuit.
The board is delivered tested and all required SMD components soldered down. Connectors and headers are included, and you can choose to get them soldered down or not.
Additionally, we recommend following addon products:
