Is the transmitter beside your studio computer or at another site? A short local connection often favours direct MPX. A remote site requires a suitable studio-to-transmitter link. Decide whether that link carries ordinary programme audio or the full composite signal before choosing equipment.
Route A: a local MPX cable
Check the interface bandwidth, output level and driver support. A sample-rate setting on its own does not prove that the analogue output preserves the full composite signal. Use the cable, grounding and input arrangement specified by the equipment manufacturer.
Route B: a network link
A remote transmitter can receive programme audio through a compatible network link and generate the stereo composite signal at the transmitter site. Transporting an already-generated composite signal requires equipment specifically designed for that purpose. Match the sender, receiver and transmitter input; an ordinary internet-radio player is not a composite-signal decoder.
Confirm the features and licences at both ends. Network capacity, packet loss and buffering affect operation. Plan remote access and a fallback programme source as part of the installation.
Compare the practical trade-offs
| Question | Direct MPX | Remote link |
|---|---|---|
| Where does it fit? | Computer near the transmitter | Studio and transmitter connected by a network |
| Essential hardware | Suitable MPX output interface | Compatible encoder and decoder |
| Main checks | Bandwidth, levels, noise and driver stability | Network reliability, settings and compatibility |
| 192 kHz studio sound card? | Follow the MPX generator and interface requirements | Not required solely for network transport |
Before ordering
Write down your transmitter model and input option, the computer operating system, the interface you own and whether a network link is required. Send this list to PCS for a compatibility check. Avoid buying the transmitter and the studio output as unrelated decisions.
