Parts of the Power Amplifier 

1.

Output jacks:

Accept 4 mm banana plugs 

(shielded or unshielded) to connect a device to the 
Power Amplifier.

2.

Output-on indicator:

Lights to indicate that the 

output is switched on.

3.

Over-current indicator:

Lights to indicate that 

the output voltage may be clipped or distorted.

4.

Signal leads:

Connect to the Xplorer GLX. 

They transmit the signal from the GLX to be amplified 
and return information about the output current to the 
GLX.

5.

Power indicator:

Lights when the Power 

Amplifier is connected to and powered by the AC 
adapter.

6.

AC adapter port:

Connects to the included AC 

Adapter

7.

Heat sink:

Dissipates waste heat. The heat sink 

may get hot (up to about 60° C). Ensure that the fins are 
vertical and that the flow of air around the Power Ampli-
fier is not impeded.

8.

Cord clip:

Holds the signal leads for storage.

Set-up

Before using your Power Amplifier for the first time, make sure that 
your GLX is running firmware version 1.44 or later. The version num-
ber appears at the bottom of the splash screen that appears briefly when 
you turn on the GLX. To download the most up-to-date GLX firmware, 
visit www.pasco.com/glx and follow the instructions on that web page.

1.

Connect the AC adapter to a wall outlet and to the power input port 
of the Power Amplifier

2.

Connect the Power Amplifier's signal leads to the GLX. Connect 
the larger plug (with the 

 icon) to the GLX's Signal Output 

port; connect the smaller plug (

) to the Voltage Port on the side 

of the GLX.

3.

Turn on the GLX by pressing 

or plugging in the GLX's AC 

adapter.

4.

Go to the Output screen and set 

Output Device

 to

:

a.

Press 

to go to the Home Screen.

b.

Use the arrow keys to highlight

and press 

. The 

Output screen opens.
