Safety and Care
Follow these safety and care guidelines for proper operation
and maintenance of the system:
• The amplifier and the loudspeaker are intended mainly
for indoor use. Do not use the system outdoors when it is
raining.
• Keep the product away from any heat source or
dampness.
• Keep the components free from all liquids.
• The system should be used only in locations with an
ambient temperature below 60°C or above -10°C.
• Follow the connection directions carefully. A wrong
connection can damage the product or its connected
parts.
• Do not try to repair this product yourself. If damaged,
send it to Larson Davis according to the directions
provided at www.larsondavis.com.
Storage
To store the system for long periods of time, remove the
main power supply cables from the socket and put the
loudspeaker in its case. Remove the battery from the remote
control.
Cleaning
Use a damp cloth to clean the outside of the system. Do not
use cleaning solutions, chemicals, or solvents as they may
cause damage.

CHAPTER
2First Use
This chapter outlines the steps to unpack the Model
BAS002 Power Amplifier and prepare it for first use.
Preparing for first use includes the following:
• Unpacking and inspection
• Assembling the amplifier and speaker
• Installing the remote control battery
• Powering-up the Model BAS002
Unpacking and Inspection
Your BAS002 has been shipped in
protective packaging. Please verify
that the package contains the items
listed below. Retain the packaging
for safe shipment for calibration
service. Report any damage or
shortage immediately to PCB
Piezotronics, Inc. at 888 258-3222
(toll free) or [phone].
The BAS002 includes the following:
• BAS002 Power Amplifier
• Amplifier hardcase (17x21x9)
• ISM antenna
• Hand-held remote control
• USB device
• Power supply cable

Please record the purchase date, the
model and serial numbers for your
amplifier, sources and remote
control in the spaces provided on the
copyright page. You will find model
and serial numbers on the labels on
the back of the devices.
The amplifier display screen is covered with a protective
film. Carefully peel it off without using a scratching tool.

BAS002 2-2
Assembling the Amplifier and Speaker
To prepare the amplifier and connect it to the speaker, follow
these steps:
Remember to turn the antenna
horizontally (or remove it) when
transporting to avoid damage.
Step 1 Mount the antenna, screwing it on the gold-plated
connector on the on the front panel.
Step 2 Before connecting the power cord, check that the
mains voltage is in the correct range for the version
purchased: BAS002-U 90-132.5 VAC (55-65 Hz) or
BAS002-E 190-265 VAC (45-55 Hz). The power supply
specifications are displayed on the back panel.
Step 3 Place the amplifier vertically on a firm surface and
place the tripod in a stable position.
Always stop signal generation and
disconnect AUX in before connecting
or disconnecting the speaker cable.
Step 4 Connect the amplifier to theBAS001 or BAS003
with CBL182 (Speakon cable). Insert the plug into the right
side CBL182 connector of the amplifier. Only one position
is allowed. Turn it clockwise until you hear the locking
click. Repeat the same steps to connect the source side.
Step 5 Connect the AC power cord.
Installing the Remote Control Battery
To install the PP3 battery in the remote control, follow these
steps:
Step 1 Remove the remote control from the rubber boot.
Step 2 Open the bottom slide to access the battery
compartment. Note the polarity indicators and insert the
battery accordingly.

Step 3 Reassemble.
FIGURE 2-1 Remote Control Bottom
On the top of the remote control, press the power button to
turn the remote on or off.
Powering-up the Model BAS002
By default the value of the power
output is set to -40 dB, the amplifier
is set to Stop mode, and the auxiliary
input is not connected to the final
power amplifier stage.
To power up the system, press the power switch on the rear
panel of the amplifier. This will turn on the display and
generate a tone sound sequence from the internal speaker of
the amplifier.

BAS002 2-4
If an incorrect AC power voltage is
supplied, the protection fuse will be
blown and the amplifier will not
switch on.
FIGURE 2-2 BAS002 Amplifier Display
The amplifier should be connnected
to a grounded socket.
The default source input is the USB port. The LED near the
USB port will flash green and red rapidly during power up,
and then will remain off until a USB device is put into the
connector.

CHAPTER
3BAS002 Power Amplifier
This chapter describes the components, features, and
basic operation of the BAS002 power amplifier.
Components and Features
The BAS002 Power Amplifier generates specific signals
useful for acoustic applications and tests. It can also be
connected to the Model 831 sound level meter to simplify
and speed up RT-60 measurements.
The power amplifier consists of the following components
or features:
• USB interface and player
• Auxiliary preamplifier and limiter
• Volume control and filter shaping
• Final power amplifier
• ISM Radio Receiver
• Display and keypad interface
• Power supply and filtering
Before powering down, stop any files
from playing or stop the Aux input.
Although the amplifier is protected
against abrupt source interruption,
the speaker may be damaged if an
interruption occurs during high
sound output.
All functions are controlled by a microprocessor with
internal flash memory for saving settings and configurations.
The housing has been designed for field usage, being both
light in weight and equipped with shielding to prevent
electrical disturbances.
The system provides three different controls, as follows:
• BAS002 amplifier keypad controls
• Remote control
• Software control
The amplifier keypad provides extended functionality over
the remote control and the software controls provide
extended functionality over the amplifier keypad controls.
Each control can be used simultaneously during operation.

BAS002 3-2
The amplifier provides the following interfaces:
Front Panel: Display, keypad, AUX input connector, ISM
Antenna for remote control (right side panel), the ethernet
connector, monitor output, and the trigger connectors.

Connections
POWER IN
The BAS002 is powered as either 110V (U version) or 220V
(E version) AC nominal voltage.
Ensure that proper connection for
the signal is made by twisting the
connector clockwise.
SIGNAL OUT
The signal/power cable to the BAS001 or BAS003 speaker
uses CBL182 (Speakon) connecter and is located on the
right side of the unit.

BAS002 Display and Keypad 3-4
SIGNAL IN
The AUX IN or USB connection is available for input
signals.
ANALOG OUT
This output offers the “monitor signal” that goes to the
speakers before being amplified.
RJ45 ETHERNET
This connecter is used with control software and fixed IP
addresses to remotely control the amplifier. Use a crossover
cable to connect directly to a PC or a straight cable to
connect to a switch or router.
