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 :
GAIN G1 G2
8dB OFF OFF
16dB ON OFF
24dB OFF ON
32dB ON ON
Adjust the internal volume (anti-clockwise for
Note.
Factory preset the gain and volume :

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.
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.
5. WIRING CONNECTION AND WIRING BALANCED INPUT

6. INSTALLATION PRECAUTIONS
Local codes may be required for other installation methods. Check with authority
having jurisdiction to determine acceptability of the mounting methods.
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.
