Solidyne HL240 Professional Telephone Hybrid for Broadcast & VoIP

Solidyne HL240 is a professional 4-line telephone hybrid and telco mixer for broadcast that combines POTS, Bluetooth mobile and VoIP calls with built-in conference mixing and voice quality restoration.

Solidyne HL240 is a professional four-line telephone hybrid and telco mixer for radio and TV studios that need to put multiple callers on air from different platforms. It combines two POTS landlines, two independent Bluetooth channels and VoIP connectivity in one unit so phone-ins, interviews and contributions can be handled from a single interface.

The HL240 uses two analog hybrids with adjustable line balance and strong local signal rejection for POTS lines, plus two Bluetooth 4.0 channels that support standard headset and audio profiles for smartphones and tablets. A VoIP/SIP option allows direct connection to IP telephony or PBX systems, while the internal conference mixer lets up to four callers be aired individually or together using one or two console faders. Solidyne’s Voice Quality Restoration (VQR) processing enhances speech clarity and restores presence lost in the phone network, giving callers a more natural broadcast sound.

Rear-panel balanced inputs and outputs integrate easily with any console using mix-minus sends, and built-in surge protection with RF filtering keeps the system stable even in transmitter-rich environments. This makes the HL240 suitable for both main studios and backup or newsroom positions where reliability is critical.
