Do not operate the speaker for an extended period
of time with the sound distorting. Doing so may
cause the speaker to overheat, resulting in a fire.
Do not stand or sit on, nor hang down from the
speaker as this may cause it to fall down or drop,
resulting in personal injury and/or property damage.
3. GENERAL DESCRIPTION
The Q-SC-P620 is a highly intelligible speaker with a built-in 20W digital power amplifier, that provides public address

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 :
Adjust the internal volume (anti-clockwise for
volume down or clockwise for volume up)
until the output level is adequate. If the output
level is insufficient, set the gain to the next
highest gain, according to the table and
repeat the precedure with the internal
volume.
2.
Note.
Factory preset the gain and volume :
* Gain setting : 16dB
* Internal Volume : Maximum
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.
3.
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.
