Speaker Cable - SWR SM-500 Bedienungsanleitung

LEFT & RIGHT (STEREO) SPEAKER OUTPUT JACKS
There are two 1/4" jacks and one Speakon
the SM-500. The Left and Right speaker jacks are provided for use in the Stereo Mode only. DO
NOT use these jacks when the SM-500's Power Amp Assign switch is in the "Bridge" position. You
can balance the Left and Right channels by using the Stereo Master Volume control located on
the front panel. Make sure all speakers are connected BEFORE turning on the amplifier whenever
possible. Connecting (or disconnecting) your speakers while the amplifier is on is not recommend-
ed.
SPEAKON VS. 1/4" JACKS
We have found the Speakon connection to be superior in both stability and amperage conductivity,
so we have provided Speakon output jacks in addition to the standard 1/4" jack. If the Speakon
output jack is used, we highly recommend a Speakon-to-Speakon speaker cable (supplied with the
SM-500). If your speaker enclosure does not have a Speakon input jack, you should use the 1/4"
output jacks on the SM-500 and connect them accordingly.
Note: All SWR Professional Line speaker cabinets come equipped with Speakon input jacks.
The SM-500's Speakon jacks are wired "standard"" (+1/–1) and additional Speakon-to-Speakon
cables are available through most music stores.

SPEAKER CABLE

Speaker cable should be made of 18-gauge, or heavier, wire. (The thicker the wire, the lower the
gauge, so 18-gauge is heavier than 20-gauge and so on.) Do not use instrument cables to hook
up your speakers. This can result in intermittent power loss, cause your power amp to oscillate,
and damage itself and/or your speakers, and render the cables useless for any purpose.
BRIDGED OUTPUT SPEAKON
The Speakon jack marked "Bridge," located directly below the Power Amp Assign Switch (in the
center of the "Speaker Outs" section), is provided for use in the Bridged/Mono mode only. A six-
foot heavy-duty speaker cable (Speakon-to-Speakon) is provided with each unit for your conve-
nience. MAKE SURE that the Power Amp Assign switch is set to "Mono" when using this jack!
The frequency response of the SM-500 is far greater than usually found in musical instrument
amplifiers (10 Hz to 40kHz). This was engineered in order to give the bass player the same punch
and clarity on stage as found in the studio or concert PA systems. Therefore, it is doubly impor-
tant that you be aware of the impedance and power rating of the speakers that you intend to use
and that they are compatible with the SM-500.
Note: Make sure your speakers can handle the power provided by the SM-500 in the Mono/Bridge mode.
Speakers that have been overdriven are easy to detect and generally do not fall under a manufacturer's warranty.
EFFECTS SECTION
Both Mono and Stereo Effects Loops are provided on the SM-500. It should be noted, though,
that both cannot be used simultaneously. Always use high quality shielded patch cables for all
connections between the amplifier and your effects units. Also, it is recommended that the cables
be as short as possible.
