solidyne hl202 1

The Solidyne HL202 controls two telephone or cell phone lines, Two or three HL202 units can be linked to handle four or six phone/cell lines. These units summarize our experience of 45 years in the manufacture of telephone hybrids for broadcasting.

This results in a system where excellence is set in the design, facilitating the work of the operator. HL-202 has sent and receiving audio limiters and compressors, as well as band-pass filters to automatically adjust levels and avoid saturation of telephone lines that often occur with other hybrid brands.

They can operate with any console model. The cabinet has rack-ears so they can be rack-mounted or operated on a table. Rejection exceeds 40 dB Then the audio quality on-air is so good that amazes your audience.

Rear panel. You can see the LINK connector to increase

the number of lines, without changing the existing HL-202

Each line allows you to set the exact line balance. It is adjusted only at the installation. A recording output allows you to use the hybrid without a console.

Each line accepts an auxiliary phone set usually associated with Production for attending income calls. When lines are on Hold the auxiliary phone set is disconnected.

Unlike other brands, this hybrid offers 8 dB cross gain to compensate for the losses of the lines. This allows for excellent conference levels between different callers.

Two or three hybrids can join with a connection
