INTRODUCTION
INSTRUCTIONFORCONNECTIONS
:
We warmly congratulate you for the choice of these excellent and
professional apparatus. Please follow these instuctions carefully, to obtain
the best results.
The wireless system SET 7700 is composed of an efficient wireless
trasmitter microphone acting in VHF band and of a sensitive receiver, which
is able to pick up the output radio coming from the microphone amplifing the
audio modulation and giving it to any amplifier, player, recorder or mixer.
SET 7710 model has the same characteristics but it is a Diversity model that
means that ist receiver grants a signal reception without any fading
surround effects.
The electric circuits of these sets, the high affidability of their components
have been planned to assure you the maximum stability of working, to avoid
the noises in the audio frequency connections, free yourselves by the
condition of the connection cable.
In order to avoid any kind of interferencies, please note that the 12V
transformer is separate from this wireless system. Thanks to the antenna
and the good quality of components used assure you a perfect receipt in a
wild range of operation.
This manual shows all useful information about both wireless system that
are SET 7700 and SET 7710. Follows the indications that refer to your
model and that will be well pointed out each time.
For each description refer to the pictures, showing commands and power
supply positions.
a – Be sure that the power switch (4) of the receiver and commutator of
the wirelessmicrophones (8) be on ìOFFî.
b – Be sure that the jack of transformer be good inserted into its DC-IN
plug (7) and then fit in the transformer plug into the 220V-50Hz
current socket. Should you need to plug wireless microphone
system with the electric lighter of your car, be sure that the voltage
stated be right and the polarieties of plug be correct.
reversed polarities or wrong voltage could cause
damages to your wireless microphone system.
reversed polarities or wrong voltage could cause damages to your
wireless microphone system.
c – Extend the telescopic antenna of the receiver (5) in all its lenght and

be care that they are in high position and not near screened
components or of electrical disturbs. For SET 7710 model do the
same for both telescopic antennas (5).
d – Keeping still the wireless microphone, turn the bottom of its handle
(9) in anti-clockwise: it unscrew itself to open the battery
compartment.
e – Insert the 9Volt battery respecting the right polarities and re-screw
the handle of the wireless microphone. Be sure of the working
moving the (8) switch on ìONî.
A red lighting up of the led (10) will state you that the wireless
microphone is working. If unused for a long period remove the
battery from the microphone, to avoid the acid leakage from battery.
f – Insert the small cable with the jack into the ìOUTPUTî
(6) sockets. The other cable-end must be connected to the input of
your recording or amplifying apparatus, using if necessary use an
adaptor.
once completed the connection between the receiver
and your audio apparatus, act on ìPOWERî(4) switch, the
ìPOWERî led (1) will light up. Put on ìONî commutators (8) of
microphone. The lighting off of led (10) during the operation means
that battery must be replaced. The microphone switch has three
steps: off/stand by/on. Using the Set, for long pauses we suggest to
put the switch (8) on ìStand byî position it will be connected but
no audio signal will be sent to the receiver and battery
consumption will be strong reduced. Led (2) will light up when
microphone is powered on to state the good connection of
microphone. For SET 7710 two leds will state the best receiving way
if antenna ìAî or îBî.
act on volume control (4) to adjust up to the
wished level, to obtain the best results without any distorsion or
ground noise act on controls of the apparatus connected to the set.
: the ìSQUELCHî function can be adjusted by acting under
its base using a little screw-driver. This function is used to optimize
the performance by balancing sound quality/clarity with overall
system range.This adjustment will guarantee a clear, uninterrupted
signal but will reduce overall system range.
going away from the receiver with the
microphone switched-on, you will see the area of capacity: the
flashing or the switching-off of the led (2) will state you that signal is
no more reliable. In particular conditions for SET 7710 model will

avoiding any surrounding effects.
the connection between the wireless
microphone and the receiver, takes place via radio, therefore can be
interfered by strong electro-magnetic range or by radio signals that
are on the same operating frequency. In case the led (2) be switched
-on even if the wireless microphone is switched-off, it means that the
frequency is occupied by other transmitter: in this case it is
necessary to change the frequencies of receiver and wireless
microphone but this operation should be done by skilled personnel.
during the conversation it will ligth up
intermittent stating the closest saturation level. The continuous
lighting up of the led (3) means the necessary to reduce the voice
volume.
the receiver can be let switched-on indefinitely and
will be working immediately at the switch-on of the radio transmitter
microphone. If you wish a temporary pause of the connection, put
the commutator (8) of the wireless microphone on central position
(STAND-BY), while if you will not use the apparatus for a long
period, put the commutators (8) of the wireless microphones and
that one of the receiver (4) on ìOFFî.
a – Do not open the equipment without due precautions, in oder to avoid
electric shocks because of the inner high-tension points of the
receiver. Reparations must be done by skilled personnel.
b – Avoid to expose the apparatus to the sun or to heat sources, such as
radiators, stoves etc. If unused for a long period, disconnect the
receiver and remove the battery from the microphones.
c – Clean only with a damp cloth, avoiding detergents or solvents.
d – Uncorrect connections or shielding of the cable connection can
cause buzzings. Control carefully cable an jack pins. Keep receiver
far away from disturbing sources, like neon lamps, reactors, motors
and so on.
e – Handle with care, avoiding rough movements. Do not drop the set.
d – Avoiding of noises:
