Carvin 1584-1584p ユーザーズマニュアル

For any distance over 25’, use a balanced source. Use the balanced XLR or

1/4” connectors featured on the rear connect plate. You may DAISY-CHAIN as
many speakers as you wish. All connectors are wired in parallel.

To start the initial hook up, be sure the 12dB pad switch is in the “IN”

position.  This will be the least sensitive position for your input source.  If your
signal is weak, depress the Pad switch to the “OUT” position, which will raise
the level of your powered speaker.

Unlike other limiters, the SPS™ incorporates an exclusive optoisolater limiter

system, which does not add distortion when limiting.  Soft limiting starts to
occur when you approach the maximum output of your powered speaker
allowing you to get more usable power out of your system without severe
clipping. However, when you hear distortion, hard clipping or cutting out, reduce
the overall level as you have exceeded the system’s capacity.

When the system has been activated by the power switch, the LED will

indicate GREEN.  If the system should go into protect, the LED will indicate
YELLOW which may occur if; a) one of the internal drivers short or b) if the
power amp should require service. 

The 1584P is available in either 120V or 240V models.  Always use dedicated

circuits for powered speakers.  Every Carvin SPS™ powered speaker is
designed to be left on continuously in the case of permanent installations.

Carvin’s SPS™ SMART POWERED SPEAKERS™ are more than just

another “power amp in a cabinet”.  They offer advanced electronics to
perfectly control every speaker component.   Woofers are power-
managed through active filtering, allowing more low-end punch and
preventing over excursion.  Midrange drivers reproduce exceptional
detail without harshness, and the top-end is crystal clear.  The exclusive
optoisolator limiter helps keep your peaks under control reducing
distortion. Surprising transparency is delivered by pure, uncolored
power from ultra-fast slew rate power amps. 

The heart of every Carvin SPS™ powered speaker is our exclusive

Digital Powered Processing Amplifier (DPPA™), which is fundamentally,
a very sophisticated delta-sigma V/A converter.  The amplifier's THD is
less than .1% from 20-20k Hz.  The 1584P SPS™ offers 300 watts
direct to the drivers with no cable loss. SPS™ powered speakers have
an incredible 91% efficiency allowing you to run more powered
speakers from the same 15 or 20 amp AC circuit.  They run cool
because power is not wasted into the heat sink.  This also means you
can expect full output 24 hours continuously - not reduced as with other
systems when they get hot.  Of course, mute and protection circuits are
standard to save your gear from any unfriendly stage conditions.  The
biggest advantage of Carvin powered speakers is rock-solid reliability
and convenience while only adding 6 lbs over the weight of our
standard enclosures! 

SMART POWERED SPEAKERS™ are easy to connect via a 1/4” or

XLR balanced inputs.  Daisy-chain as many powered speakers as you
need for additional coverage.  A 12 dB gain switch matches every audio
source.  A removable AC cord frees the enclosure when transporting.
