3. GENERAL DESCRIPTION
The Q-SC-P620 is a highly intelligible speaker with a built-in 20W digital power amplifier, that provides public address
announcement and remote paging via network video surveillance applications. Its powder-coated finish and stainless steel
screws ensure the unit’s weatherproof capability.
4. SET THE GAIN AND VOLUME LEVEL
To Set the gain and volume level of the amplifier module, please follow
instruction as below :
1. Remove 4 screws to open back cover of Horn speaker.
On the PCB, there is DIP Switch marked “SW1”.
To Set gain refer to table below :
Note.

level is insufficient, set the gain to the next
highest gain, according to the table and
repeat the precedure with the internal
volume.
INTERNAL VOLUME
ATTENTION !!
To avoid damage, do not put more
pressure when turning the internal control.
The rotational stopper strength of internal
volume is about 2.94 N.cm.
3. Now replace the rear cover. As this Horn speaker is
weatherproof to IP65, care must be taken during the
replacement of the back cover, to ensure the gaskets are
correctly refitted and watertight.
5. WIRING CONNECTION AND WIRING BALANCED INPUT

having jurisdiction to determine acceptability of the mounting methods.
[Front view]
When installing the Horn speaker, be sure the drain hole is positioned toward the
ground. Otherwise, rainwater could enter the interior of speaker and the aging of
parts may cause speaker failure.
Do not install the speaker face-up from a horizontal plane. If water accumulates in
the horn, this may cause the speaker to malfunction.
Do not install the speaker under environment that subject speaker to contamination.
