  • The phone hybrids HL-202 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 the excellence is set in the design, facilitating the work of the operator. HL-202 has sending 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 rebatibles 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.
    With the 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 console.
    Each line accepts an auxiliar phone set usually associated to Production for attending income calls. When lines are on Hold the auxiliar phone set is disconnected.
    Unlike other brands, this hybrid offers 8 dB cross gain to compensate the losses of the lines. This allows for excellent conference levels between different callers.
    HL202 - Is a two phone line hybrid system for conference (landlines or cellular phones). It is suitable for rakck or table mounting. Using two HL202 linked you get a 4 line or with 3 6 lines.
