The ETS-250 AM transmitter from Castel is designed to save you money. Sure it’s small, but it’s also less expensive than any other major manufacturer’s 500W model. The ETS-250 fits easily into your existing equipment rack without tying up needed floor space. It’s even less expensive to ship. What’s more, the ETS-250’s unique power control design can meet your night-time power requirements without expensive splitters or the need for a separate low-power transmitter. And because of this unique engineering feature, there’s less audio degradation when it’s time to reduce power.
