About the montage
Solidyne hybrids HL202 & HL203-VQ are designed to be mounted
into 19" standard racks. Require one unit (1U) of vertical clearance.
They can also be placed on a table, for which the supports are given
for rubber to adhere to the base of the unit.
When mounting the equipment into a rack, always use flat head
screws with washers flexible (plastic, rubber, etc.). Be sure to adjust
the screws lower and then higher to prevent the weight of the unit to
generate a lever arm on the upper corners.

1 O ER IEW
The professional telephone hybrids Solidyne includes models
HL202, a high quality hybrid that manages two phone lines and
allows linking to expand its capacity up to 6 lines; and the HL203-
VQ, which incorporates VQR signal processing and Bluetooth link.
Both models supports conferencing between the floor speaker and
all phone lines, be they land-line or cell phones.
RJ11 connectors support landlines or cell phones connected by
cable, via speaker phone. The detection is automatic.
HL203-VQ supports Bluetooth to pair a cell phone without needing
special cables. The use of mobile phones for broadcasting was
extended because they produce substantial savings in telephone
communications, thanks to corporate plans and promotional rates.
VQR Solidyne technology (Voice Quality Restoration) allows
reconstruct the high and low frequencies that are lost in the
telephone transmission. The user can adjust the signal level
restored from two independent knobs for bass and treble. In
addition, VQR has a noise gate allows to obtain values of 70dBA
SNR in a telephone transmission. This allows modern radios,
aspiring to be digital quality transmission, can provide outdoor
sound quality not detract local sound generated at the Studios.
The stylish design of the hybrid HL203-VQ, and its technological
advances, makes it an excellent choice for radios that seek
differentiated by its technology.
HL203-VQ may be associated with one or two units HL202 to
increase the number of lines (5 and 7, respectively). HL-202 HL203-
VQ are presented in rack-mount cabinets, 1 unit high.
1.1 Main features
1.1.1 HL-202
•Expansible to 4 or 6 lines. Up to three units can be linked
to obtain a system with 4 or 6 telephonic lines (land line or
cellular). All lines are enabled to be in conference.
•100 % compatible with cell phones: phone line inputs
supports direct connection of cell phones. HL-202
SOLIDYNE Telephonic Hybri s Page 7
automatically detects to the cell phone and switch the input
from mode 2-paths (land lines) to 4-paths (cell phone).
•An audio compressor in reception equals the sound level
for all lines, as well as originating on phone lines of high or
low level.
•Audio limiter: The transmission channel to the remote
speaker, has a band filter to eliminate frequencies below
250 Hz and above 2.500 Hz, to limit the return of signal.
Also, a peak limiter at the filter output increase the
perceived loudness at the other end of the line, freeing to
the operator from the level controls of the on-air console.
•A Priority System reduces the level of the interviewed
people (the caller) when the local journalist interrupts them.
•The operation is very simple and error free, despite its
security's logical and automated control circuits.
•A Recording Output allows recording the conferences
directly from the hybrid. This output is a mix of the audio
coming from the phone lines and the hybrid's audio input
(audio from studio console).
•Hold lines cue: An output brings the audio of all hold lines.
1.1.2 HL203- Q features
•Wireless link using Blue-tooth.
•VQR signal processing to improve the audio quality of the
phone calls.
•Expander-Gate at the audio output; to reduce the
background noise present in most telephonic
communications, since the norms for telephony requires
dynamic ranges of 40 to 50 dB; while FM broadcasting
requires 70 dB.
•Reception VU-meter, needle-type with back light.
1.1.3 Bluetooth
The HL203 supports audio transmission and reception using a cell
phone linked via Bluetooth.

2 INSTALLING
2.1 Power source
The unit is connected directly to the AC outlet, using a standard 3-
prong power plug (AC-0106 type) provided with the unit. At the rear
panel, there is a 220/110 V switch, which must be manually settled
to the correspondent position. The unit have an on/off switch.
CH CK TH 110/220 SWITCH
B FOR PLUG TO AC OUTL T.
2.2 Connecting land-lines
On rear panel (see Fig.1) there are two pairs of connectors RJ-11
type (Line-1, Line-2), where the pone lines and their correspondent
telephones sets are connected.
Fig.1 - HL-202, panel trasero, sección conectores
The telephone set operates normally while the phone lines aren’t
taken by the hybrid (position OFF). The lines can be connected
directly to the public phone lines or the PBX of radio station. The
private lines deteriorate hybrid rejection, therefore, we recommend
connecting the console to public lines directly. The hybrid have
internal filters for RF rejection effective in AM, FM and UHF bands.
Usually you don’t need to add additional filters.
HL202 and 203-VQ have protection with SIOV varistors against
voltage overshoots caused by ligthnings; is recommended to
install an external surge suppressor for each phone line.
2.2.1 HYBRID BALANCE
Balance is adjusted when the local audio from Studios returns from
hybrid too high, ‘dirtying’ the voice on-air. This non-desired effect is
produced because some part of the signal sent to the telephone line
returns through the hybrid circuit, and mixes with the original signal.
SOLIDYNE Telephonic Hybri s Page 9
The hybrid's balance adjusts in factory using standard impedances,
but you must adjust it to the impedance of local line. Proceed as
following.
•On rear panel, the unit has two rotating presets of 15 turns
(BAL), one for each line.
•Using the correspondent telephone set, make a call to an
external number (don’t use extensions of private central)
•Use a microphone (connected to the console) to send audio
to the pone line.
•Send the microphone signal to the hybrid (e.g.: using the
S ND bus). If your console allows it, assign the output of
hybrid and the headphones to an independent bus (AUD) to
don’t interrupt the on-air program while this adjustment. If
console do not allows this, connect the headphones directly
to the balanced output of the hybrid.
•Turns the BAL preset until reach the minimum level on
headphones.
Proceed in the same way with the others lines.
2.3 USING WITH CELL PHONES
2.3.1 Wired cell phones in HL202 & HL203- Q
Both RJ-11 inputs supports cell phones. The cellular connects to the
hybrid using the “free hands” connection that the cell phones have.
For make this you need a special RJ-11 cable-adapter whose
connection will depend on the brand and model of your cell phone.
You will need to purchase the “free hands” accessory correspondent
to your cell phone and to check the user manual of the unit to make
the connection according to the diagram showed above.
Cell phone connects directly to “LIN /C LLULAR” RJ11. The hybrid
automatically detects the cell phone and changes the input mode
from 2-paths to 4-paths.
The cell phone transmits through the “free hands” connector the
audio signals: microphone and loudspeaker. The HL202/203
receives, via cell phone, the remote audio (that is to say, the audio of
who is at the other end of the line). On the other hand, the hybrid
sends to the cell phone the audio from the Studios (return signal).
