Solidyne's automated hybrid operated with just three buttons. HL202: telephone hybrid for 2, 4 and 6 lines. The HL-202 telephone hybrids control two telephone or cellular lines, indistinctly. These units synthesize our 45 years of experience in the manufacture of telephone hybrids for broadcasting.
This translates into a system where excellence is placed in the design, facilitating the operator's work. The sending and receiving have audio limiters and compressors, as well as band-pass filters, to automatically adjust levels and avoid saturation of telephone lines that occur with other brands.

They can operate with any console model. The cabinet has flip-up ears so that it can be rack mounted or tabletop operated. The rejection exceeds 40 dB and the on-air audio quality is so good that it is surprising that it originates from a telephone line. Rear panel. The LINK connector can be seen to increase the number of lines, no need to change equipment. Each line allows you to adjust the exact balance. Fits only when installing. A recording output allows the hybrid to be used without a console. Each line accepts an associated telephone, for Production, which is disconnected when put on hold (Hold).
Unlike other brands, this hybrid offers 8 dB of crossover gain to compensate for line losses and make everyone hear each other at a good level in a conference. Two or three hybrids can join with one connection. The operation can be obtained with 4 or 6 telephone lines or Cell phones. The keypads have highly visible reflection-illuminated buttons, which make operation errors impossible. A red LED flashes with line on hold (HOLD) and marks bright with the line on the air. Blue LED indicates the line you are calling. Hybrids allow you to enter either with landlines or with cell phones, using the cell phone's hands-free cable. The hybrid recognizes the different inputs and is automatically configured to operate in 2 wires (TF line) or in 4 wires (cellular)
The Hibrido HL 202 owes its excellent on-air audio quality to its elaborate design that synthesizes our 45 years of experience in this field.
We want you to thoroughly investigate the reasons that make them the best product on the market, analyzing the circuit block diagram. You'll find that your track incorporates technologies never seen before in competing hybrids, even much more expensive than ours.

Removable sides
The Hybrid can be used interchangeably on a table or in rack mounting, as it has removable sides and self-adhesive rubber feet
Lines: | |
| 2, 4 & 6 phone or cellular lines. |
