E. POWER
SWITCH
—Switches the unit ON-OFF.
F. IEC POWER CORD SOCKET
—Connect the included
power cord to a grounded A/C electrical outlet in
accordance with the voltage and frequency ratings
specified on the top panel of your amplifier.
G. SPEAKER OUTPUTS
—Connect speaker cabinets here
using the Speakon® connectors. The total speaker load
must be 4Ω minimum and capable of handling 400
watts (300 watts for 100V Japanese models). Read
Speaker
Guidelines
below before making speaker connections.
CAUTION
: The speaker output cables have
voltage present on BOTH conductors and
the amplifier will shut down if either one comes into
contact with a grounded surface.
CAUTION
:
Any exposed metal on plug
jackets or cabinet input panels must not
touch ground when speaker cables are connected; use
insulated (plastic) plug jackets whenever possible.
H. PASS-THROUGH*
—An output copy of the input signal
for connecting (daisy-chaining) additional power amps.
I. INPUT*
—This is an alternate input to the front panel
Input {A}. You can use either a 1/4" plug or an XLR plug
with this combo input.
•
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.
The speaker illustration (left) shows the impedance
load totals for various speaker combinations
(Ω=ohms). The ideal speaker impedance load is
equal to the minimum impedance rating of your
amplifier. Note that using speakers of unmatched
impedances will result in an unequal distribution
of power with most of the power going to the
lower impedance speakers.
Operating below the amp's minimum
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.
