Introduction
Thank you for selecting the JBL Active 1. This product is designed to deliver optimal performance, functionality and
years of reliable operation . To enjoy all the benets of the Active 1, please take a moment to read this document.
The versatile JBL ACTIVE-1 provides essential monitoring functions that enhance the work ow in professional
recording, post production and broadcast applications, making it a valuable control room upgrade. The ACTIVE-1
accommodates four input sources (3 x stereo analog and 1 x USB) and provides three stereo analog outputs plus
USB. In addition to allowing seamless A/B switching of input signals and monitor systems, the ACTIVE-1 delivers a
full complement of audio monitoring functions, including a precision volume control, mono summing, mute and dim.
A footswitch activated talk back system with an integrated condenser microphone allows communication with talent
via the ACTIVE-1 headphone outputs, while routing voice "slates" to recording devices.
The ACTIVE-1 was designed with computer audio production in mind. On-board USB I/O provides a direct interface
of the ACTIVE-1 to a computer, allowing computer system recording of all the input sources connected to the
ACTIVE-1. At the same time, the USB functionality allows monitoring of the mix created on the computer.
Housed in a sturdy metal chassis and tted with an array of switches and secure connectors, the ACTlVE-1 is built
to provide years of reliable operation.
JBL may update the contents of this manual without prior notice. The most recent version of this manual can be

Connections (rear panel)
Mains Power
The ACTIVE-1 includes an external AC power supply. The power LED on the front panel (to the left of the volume
knob) will illuminate when the external power supply is connected and mains power is present. Please ensure the
correct power supply is used with the ACTIVE-1 and that the power rating on the provided power supply suites
your AC power outlet. Please make sure your Mains voltage is compatible with the provided adaptor.

6
Inputs
Three sets of input connectors are provided to allow connection of three signal sources. Input types for the three
sources are as follows.
•Source A: Stereo RCA inputs
•Sources B and C: Two stereo sets of 1/4-inch (6.5 mm) input connectors
•Source D is the USB input. The USB input has a built in Legacy compatible driver for simple plug & play
operation. The USB input does not need mains power to operate. An ASIO driver is also available for
download from the JBL Professional website at www.jblpro.com.
Outputs
Three sets of output connectors are provided to allow ACTIVE-1 connection to powered studio monitors, PA
speakers, mixers and recording equipment. Input types for the three sources are as follows: They are line level signal
for plugging in your active studio monitors or to the inputs of a power amplier that is driving your passive monitors.
• Outputs A and B: Two stereo sets of 1/4-inch (6.5mm) TRS connectors.
• Output 2T (2 Track): 1/4-inch (6.5mm) TRS connectors that can include the talkback signal.
• Source D is the USB output with Legacy driver built in. USB does not need mains power to operate.
USB output caries the same signal that is selected using the MAIN SOURCE input.

TALK BACK Foot Switch Jack
You can connect a foot switch with two-conductor (Tip/Sleeve) plug to this 1/4-inch (6.5mm) jack. (optional and not
included with ACTIVE-1*) Depressing the foot switch will activate the Talk Back system.
* A momentary PRESS-AND-HOLD type of foot pedal is commonly used with electronic musical keyboards.
Alternately, if you prefer a PRESS-ON, PRESS-OFF (latching-type) foot switch, these are commonly used to
activate effects processing in guitar ampliers. Consult with your dealer for options.
+4/-10dB Output Level Switch
This switch is used to select the output level to allow compatibility with professional and consumer products with
varied input sensitivities.

Front Panel
Switches
Use these switches to select input signal you wish to monitor.
Headphone Amplifiers
There are two independent headphone ampliers provided on the ACTIVE-1. Each with its own volume control

9
Dim Switch
Activate this switch to decrease the level of the outputs by 20db. The DIM feature effectively reduces the output
signal and therefore the listening level to allow discussion in the control room without having to change the position
of the volume knob.
Mute Switch
Activate this switch to prevent signal output.
Mono Switch
Activate this switch to listen to the audio outputs in monophonic mode. This combines the stereo audio signal into
a monophonic signal, which is useful when checking for any phase cancellation issues in the stereo signal.
Volume Control
As it is an ACTIVE device, the ACTIVE-1’s Volume control, controls an electronic circuit, which in turn adjusts the
level of the audio going through the device, providing gain increase as well as attenuation.

10
Talkback Switches and Volume
A built-in talkback microphone, can be routed to the headphone outputs or the 2TRACK outputs. When the Talkback
function is engaged, the Control Room output signal is attenuated by 20 dB.
Monitor Select Switches
The monitor select switches activate the A & B outputs respectively. The A & B outputs can be selected simultaneously.

11
Applications
The ACTIVE-1 provides essential monitor controls in a professional control room. In this
application, ACTIVE-1 allows monitoring using both large and near-eld studio monitors. A
mixer, 2 microphone preampliers and a DVD player can be recorded by a computer audio
recording system. The computer recording system is connected using the USP I/O that also
allows monitoring of the computer. An additional two-channel recorder is connected to the 2T
outputs allowing stereo recording.
When connecting PASSIVE speakers, you must rst connect the output of the ACTIVE-1 to a power amplier and
then connect the amplier to the speakers.
Do not connect the OUTPUT of a power amplifier to the ACTIVE-1 INPUTS!
