202 Telephone Hybrid for
2, 4 & 6 lines
Photo model
HL202
These
hybrids synthesize our 45 years experience in developing telephone hybrids
for broadcasting. This is a system where the excellence was applied to
the design, facilitating the operator's work. The audio send and the reception
have band pass filters and limiters / compressors to control the audio
levels. HL 202 can operate with all console models. Is able to accept
terrestrial phone lines (2 wires) or cellular phones (4 wires). The cabinet has detachable
lateral supports to be mounted in rack or to operate on a table.
The local sound rejection surpasses 40 dB and the quality of audio signal
on air is so good that it will surprise your audience.
It is not easy
to realize that the sound comes from a telephone line …

panel. The new LINK connector allows increasing the number of phone lines
Each
line allows setting individual hybrid balance. You only need to set the
balance when install the unit, using a precision 15 turns potentiometer.
A recording output allows to use the hybrid without console. Each line
accepts an associated telephone, for producers, that is disconnected when
take a line on-air. Unlike other brands of hybrids, this unit offers 8
dB gain between conference lines to compensate the losses of the lines.
Two
or three hybrids can be used linked by D9 connector
This way HL202 can improve to 4 or 6 lines

The
unit have buttons that illuminates by reflection.
Its good visibility avoids
operation errors
A red
LED blinks when the line is in waiting mode (HOLD) and remains illuminated
when the line is on-air.
The blue LED indicates when the line has an incoming call
HL 202 allows
using standard telephone line or cellular phones, using the "free hands"
connector. The hybrid recognizes the different inputs and automatically
changes to operate in 2 wires (line) or 4 wires (cellular)
This feature allows the radio station to take advantage of the low cost
communication fare between corporative cellular phones, that the cellular
operators offer
Permanent
monitoring of lines on HOLD
You
can listen the telephone or cellular lines when they are on HOLD. Connect
a set of active speakers (i.e. PC multimedia kit) to the CUE monitor output.
For example, if you have lines 3 and 4 on the air; the journalists of
lines 1 and 2 are listening to the air program. But, if an important event
takes place, journalists can speak to the operator or producer, and they
are immediately attended.

Do
you like to know more about the new
VQR technology ?
This
new technology, that only Solidyne offers, allows for a new landmark
in telephone audio quality: The restoration of the original audio quality
of the human voice (VQR = Voice Quality Restoration). In this way, the
system can obtain a frequency response equivalent to 50-12.000 Hertz through
a telephone or cellular line, even though the voice is generated by a
standard telephone set !
