Specifications - SWR Black Beauty Bedienungsanleitung

• DO NOT connect a speaker load with a impedance
total below the minimum rating of your amplifier
to prevent damage to your equipment.
• DO NOT connect speaker(s) with a power handling
capacity total that is less than the power output
rating of your amplifier to prevent damage to
your equipment.
• ALWAYS switch your system power OFF before
connecting or disconnecting speakers.
• ONLY use unshielded speaker cable of 18 gauge or
heavier (16 or 14 gauge) for speaker connections.
Shielded instrument cable WILL NOT work and
may damage your equipment.
• ONLY connect one amplifier to each speaker load.
Two amplifiers connected to a single load WILL
NOT work and may damage your equipment.
Use the impedance and power ratings on
your amplifier and speakers to determine if a particular
combination of speakers is appropriate for your amplifier.
NOTE: All SWR® speaker enclosures, as well as most others,
will be connected in parallel (NOT series) when linked (daisy-
chained) together. Therefore, these guidelines apply only to
parallel speaker configurations.

The speaker illustration (left) gives you the impedance
load totals for various speaker combinations
( =ohms). The ideal speaker impedance load is equal
to the minimum impedance rating of your amplifier.
Operating below
impedance rating can overheat your amplifier
and cause damage. Operating above the amp's
minimum impedance rating, while safe, reduces
the amplifier's maximum power output.
Something else to consider: You can obtain
the same total impedance load from different
combinations of speaker impedances (see
illustration). If each speaker in a group has
the same impedance, each speaker will receive
the same amount of power from your amplifier.
However, if impedances are not all equal, the lowest
impedance speakers will get the most power. For
example, if you connect an 8
an amp output of 30 watts, the 8–ohm speaker will
receive about 20 of those watts (and be twice as loud as the
16-ohm speaker). Take this into consideration when calculating
power handling capacities and when positioning your speaker
enclosures.
