For Products with Radio Receivers
That Can Use an External Antenna:
CATV or Antenna Grounding
If an outside antenna or cable system is connected to this
product, be certain that it is grounded so as to provide some
protection against voltage surges and static charges. Section
810 of the National Electrical Code, ANSI/NFPA No. 70-1984,
provides information with respect to proper grounding of the
mast and supporting structure, grounding of the lead-in wire
to an antenna discharge unit, size of grounding conductors,
location of antenna discharge unit, connection to grounding
electrodes and requirements of the grounding electrode.
Note to CATV System Installer:
This reminder is provided to call the CATV (cable TV) system
installer’s attention to article 820-40 of the NEC, which
provides guidelines for proper grounding and, in particular,
specifies that the cable ground shall be connected to the
grounding system of the building, as close to the point of
cable entry as possible.
For CD/DVD/Blu-ray Disc™Players:
Caution:
This product uses a laser system. To prevent direct exposure
to the laser beam, do not open the cabinet enclosure or defeat
any of the safety mechanisms provided for your protection.
DO NOT STARE INTO THE LASER BEAM. To ensure proper use
of this product, please read the owner’s manual carefully and
retain it for future use. Should the unit require maintenance
or repair, please contact your local Harman Kardon service
center. Refer servicing to qualified personnel only.
For Products That Include Batteries:
Instructions for Users on Removal and Disposal of
Used Batteries.
CAUTION
Risk of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.
Alkaline batteries are considered nonhazardous.
Rechargeable batteries (i.e., nickel cadmium, nickel metal-
hydride, lithium and lithium-ion) are considered hazardous
household materials and may pose an unnecessary health
and safety risk.
In the European Union and other locations, it is illegal to
dispose of any battery with household trash. All batteries
must be disposed of in an environmentally sound manner.
Contact your local waste management officials for information
regarding the environmentally sound collection, recycling and
disposal of used batteries.
To remove the batteries from your equipment or remote
control, reverse the procedure described for inserting
batteries in the owner’s manual.
For products with a built-in battery that lasts for the lifetime of
the product, removal may not be possible for the user. In this
case, recycling or recovery centers handle the dismantling of
the product and the removal of the battery. If, for any reason, it
becomes necessary to replace such a battery, this procedure
must be performed by authorized service centers.

Each precaution in this manual should be followed during servicing.
Components identified with the IEC symbol in the parts list are special significance to safety. When replacing a component identified with
, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the
parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably
insulated from the supply circuit before retuming the product to the customer.
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called
Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and
semiconductor "chip" components.
The following techniques should be used to help reduce the incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on
your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device,
which should be removed for potential shock reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to
prevent electrostatic charge build-up or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static" can generate electrical charges
sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement
ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.)
7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the
chassis or circuit assembly into which the device will be installed.
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together
or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.
CAUTION :


SAFETY PRECAUTIONS
The following check should be performed for the continued
protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground (water
pipe, conduit, etc.) by connecting a leakage current tester
between the earth ground and all exposed metal parts of the
appliance (input/output terminals, screwheads, metal
overlays, control shaft, etc.). Plug the AC line cord of the
appliance directly into a 120V AC 60Hz outlet and turn the
AC power switch on. Any current measured must not exceed
o.5mA.
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A
POTENTIAL SHOCK HAZARD AND MUST BE
CORRECTED BEFORE RETURNING THE APPLIANCE
TO THE CUSTOMER.

There’s Nothing Better Than Riding With JBL
Stage Amplifiers
Features and Benefits
Value Engineered
Stage amplifier provides true JBL performance at an affordable price while now lacking the features needed to properly tune and optimize performance.
Compact footprint
With it becoming more and more difficult to find spacious locations for amplifier mounting, Stage has been developed in a small compact form factor
to allow more location versatility.
Full On-Board Protection
Stage amplifier has on-board circuitry to protect them from shorts, temperature, overvoltage and undervoltage. An LED indicator is included on all
four models to let you know when one of these conditions exists.
Reliability
JBL is one of the greatest audio brands in the world. This is not a coincidence given the arduous testing and quality control. We take our craft seriously
and want every consumer to have a world-class experience that lasts and lasts.
Input Level Control
When Low-level inputs are used, this control adjusts the input sensitivity between 200mVrms and 5.0Vrms. When High-level inputs are used,
this control adjusts the input sensitivity between 0.5Vrms and 15Vrms.
Switchable bass EQ
This provides an available bass boost at 45Hz of 6dB or 12dB, serving as a great tool to optimize subwoofer and loudspeaker performance based
on location and enclosure type.
Cool industrial design
Black with deep grooves, silver silkscreen, anodized JBL badge top-center with orange end panels and bottom.
Crossover mode switch*
LPF crossover controls is switchable between 0dB to 12dB at 45Hz giving user ability to adjust sound to the environment and/or application.
Crossover control gives user additional fine tuning*
Adjusts the crossover turnover frequency between 32Hz and 320Hz. (One knob for each stereo pair.)
Our Point of View
JBL believes that life is defined by what you experience. Music helps people have experiences that are more extraordinary, by fully immersing them
in each moment. To help people have rich experiences, JBL creates full-on sound that draws people in and heightens the feeling. JBL is dedicated
to delivering sound that elevates life.
