Panasonic WS-AT300 사용자 설명서

-3-

• This speaker system is a 2-way bass-reflex type

incorporating a 38-cm (15”) woofer and a Square
Contour Wave Guide (SCWG) horn tweeter.

• The speaker system accepts a continuous program

input of 400 W or 200 W(RMS). It delivers high
outputs from its compact body with a maximum
sound pressure level of 122 dB.

• The SCWG horn minimizes the disturbing reflection

sound generated near the open end and to provide
a constant directivity of 60˚ (horizontal) and 40˚
(vertical). You can easily attach again the horn to
the enclosure by turning it 90˚ as required for
horizontal or vertical speaker installation.

• The enclosure has essential features such as

toughness to transportation, a recessed type
handle for carrying, the convex and concave for
stacking, holes for mounting bracket, safety wires,
etc.

• This Subwoofer is a bass-reflex type incorporating

a 38-cm (15”) cone speaker and to be used with
the  RAMSA Subwoofer Processor WS-SP2A.

• The WS-AT350 accepts an input of 400 W (RMS). It

delivers high outputs, though it is small in size, with
a maximum sound pressure level of 118 dB.

• The enclosure has essential features such as

toughness to transportation, a recessed type
handle for carrying, the convex and concave for
stacking, holes for mounting bracket, safety wires,
etc.

• Power loss may increase as the total speaker

impedance gets lower with a number of speaker
hookups. Use the largest speaker cable in wire
gauge to reduce power loss.

• Switch off the power amplifiers before connecting

the speakers or other peripherals.

• Avoid the followings all the time to protect the

speakers from damage.

* Turning on and off mixing consoles and other

peripherals may cause shock noise when the
amplifiers and subwoofer processor are on.

* Shock noise resulting from the connection/

disconnection of inputs/outputs with any
powered-up equipment

* Pop noise from microphones without

appropriate use of breath-pop screen and/or
high-pass filter

* Click noise caused by switching on or off the

phantom power for microphones

* Continuous operation at very low frequency

from an oscillator, synthesizer or program
sources

* High frequency noise developed by fast-

forward or fast-rewind operation of a tapedeck

* Out of tune noise in FM broadcast
* Feed-back from microphones or electronics

musical instruments.

• Match the polarities of all the speakers by

observing the connectors and wire colors when
using two or more speakers.

• Read “PROTECTION CIRCUITS” on page 8. Turn

down the volume control of the amplifier
immediately if the sound suddenly decreases.

• You should use the WS-AT350 Subwoofer all the

time with Subwoofer Processor WS-SP2A. The WS-
SP2A processes the signal to protect the speakers
from damage due to an excessive input signal.
