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.
CHECK THE
110/220 V
SWITCH
BEFORE PLUG TO AC OUTLET.
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.

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.
