Feed-Through Output; Units With Line Level; Connection With The Mains - Omnitronic PAP Series User Manual

• A high damping factor of your amplifier supplies a clear sound reproduction. Unnecessarily long and thin cables
will influence the damping factor and thus the low frequencies in a negative way. In order to safeguard good
sound quality, the damping factor should lie around 50. The longer a cable has to be, the thicker it should be. In
this respect, a damping factor of 200 will be reduced to 47 (8 ohms) when using a 10 m long, 2.5 mm² speaker
cable. The power loss at 8 ohms is 1.63 %, at 4 ohms 3.25 % and at 2 ohms even 6.5 %.
• The maximum cable length is 30 meters!
Information on installing speaker cables
• Always treat cables carefully and protect them from damages during transportation.
• Install cables always in a structured way and protect them from damage.
• Cables must be installed in a way that no person can stumble over them. Always fix cables with an appropriate
tape.
• Both cables should be of the same kind.
• Both cables should have the same length.
• Both cables should be installed directly (no loops, S-shaped overlengths)
• Always install the cables far away from power cables (never closely parallel)
• Never put heavy objects like speaker systems, flightcased etc. on cables.
• Never wind up cables tightly around the elbow, but rather sleek with an interior diameter of 20 to 30 cm.

Feed-through output

For parallel connection of a further PA amplifier, the feed-through output LINK can be used via the XLR or
6.3 mm jack. Connect the output LINK to the input of the second PA amplifier.

Units with Line Level

Connect the output of a preamplifier or mixer to the XLR or 6.3 mm jack INPUT. Both jacks are provided for
balanced signals. The input signal should have line level.
Note
• Input cables should be short and direct, since high frequencies will mostly be absorbed if the cables are
unnecessarily long. Besides that a longer cable may lead to humming and noise trouble. If long cable runs are
unavoidable, you should use balanced cables.

Connection with the mains

Finally connect the device to the mains with the mains cable.
