REVO SAT208P / REVOSUBll8P INTRODUCTION

1

REVO SAT208P/REVO SUB118P passive wood loudspeaker which is professional and
versatile can be combined to diverse compact line array loudspeaker system. Line array
loudspeaker system has been very popular for recent years. Presently, after one-year efforts,
we use horn and array technologies to develop the first line array loudspeaker system that
shows our potential of developing loudspeaker.

The two-hole aluminum bracket nut, at the bottom of REVO SAT208P, is adjusted to get
different sound radiation according to voice effects. Treble driver uses weak magnet to
hasten voice coil and magnetic flux path to send heat out. We use 1.4 inch voice coil and
iron vibrating film and plastic treble horn so that the system gets narrow radiation angle
and casts too long distance. High frequency crossover uses 24dB weakening slope and
protection circuit to make sound clear and make the crossover lasting. And high frequency
design has the choice of odB / + 3dB. We select suitably in terms of distance to avoid air
absorption. So it suits for different distances and can be used with other combination
together, for example, stage performance, DISCO, theatre.

REVO SUB118P is heavy inverted bass loudspeaker which has 750W power. It can be
used with one or many REVO SAT208P loudspeakers.

The two loudspeakers use 18mm high intensity plywood painted with black scrap-proof
and waterproof spray. They have 4 dots for suspending when line array is used with other
equipments. REVO SAT208P has two BI-AMP and PASSIVE modes. According to our
love and different demands, we can use single electronic crossover and two-amplifier one
to get different sound effects. DIRECT mode and PASSIVE mode, at the rear panel of
REVO SUB118P, can be connected to external electronic crossover and inbuilt passive
crossover. And there are two fixed foot wheels to fix and two unfixed ones to move the
device at the rear panel. It is very convenient for us to use it.
