To install, refer to Figure 2.2.3 and follow the steps below:
1. Attach the front angle brackets to each side of the front of the amplier using the
screws provided.
2. Attach the rear at brackets to each side of the rear of the amplier with the
screws provided.
3. Install the unit into the cabinet using the rack mount screws through the front
angle brackets. For details of installation in the chassis of the cabinet, refer to
the user guide of your cabinet.
4. Align the rear angle brackets with the proper holes at the rear of the cabinet and
attach using rack mount screws.
5. With the rear angle brackets to the outside of the at brackets, attach them each
using a screw passing through two washers, the rear at bracket and the rear
angle bracket as shown in the gure.
12
2.3 Ensuring Proper Cooling
When using an equipment rack, keep a minimum space of 4 inches (10 cm) from
the top surface of the unit. Close any open spaces in the rack with blank panels. DO
NOT block any air vents. The side walls of the rack should be a minimum of 2 inches
(5 cm) from the amplier sides. The back of the rack should be open.
2.4 Choosing Input Wire & Connectors
We recommend using pre-built or professionally wired balanced line (two-conductor
plus shield) 22-24 gauge cables to connect the amplier balanced input by using the
included Euroblock connectors, see Figure 2.4.1. Unbalanced lines may be used,
but may result in hum or RF noise if using very long cable runs.
You can also use RCA connectors to connect audio devices, for example, CD/DVD
player. However, do not use both Euroblock and RCA audio input connectors on a
single channel at the same time.
NOTE: Custom wiring should only be performed by qualied personnel.

2.5 Output Wiring & Connectors
To drive distributed speaker systems designed to operate at 70V or 100V, connect to
the corresponding output terminals.
JBL recommends using pre-built or professionally wired, high-quality, two-conductor,
heavy gauge speaker wire. Speaker wires should be twisted cable, if possible. To
prevent the possibility of short-circuits, the wires should be stripped back no greater
than 6 mm (1/4 inch), see Figure 2.5.1.
Suggested below are guidelines to select the appropriate size of wire based on the
distance from amplier to speaker. Check with local code as this may vary.

Figure 2.6.1 Wiring Audio System
Typical input and output connections are shown in Figure 2.6.1.
INPUTS: Connect input wiring for both channels using either the RCA or the
Euroblock input for each channel.
OUTPUTS: You may use either low impedance or high impedance speakers. Always
be sure to maintain the proper polarity when wiring speakers.
Low Impedance Speakers should be driven using the +/- pins of the amplier output
connector. The minimum impedance an amplier channel can drive is 4 Ohms.
Therefore, you can connect up to four 16 Ohm speakers, two 8 Ohm speakers or one
4 Ohm speaker to an amplier output channel.
High Impedance Speakers should be driven using the appropriate (70V or 100V) pin
to speaker (+) and the COM pin to speaker (-) of the amplier output connector. The
minimum impedance that can be driven from each output is provided in Appendix
A. Note that the HI-Z switch must be ON in order to provide audio to the high
impedance outputs.
WARNING: Do not connect to both low impedance speakers and high impedance
speakers from the same audio output channel.
15
2.7 Connecting to AC Mains
Connect your amplier to the AC mains power source (power outlet) with the
supplied AC power cord. First, connect the IEC end of the cord set to the IEC
connector on the amplier; then, plug the other end of the cord set to the AC mains.
When properly connected to a live power source, the power LED should illuminate
blue.
WARNING: The third prong of this connector (ground) is an important safety feature.
Do not attempt to disable this ground connection by using an adapter or other
methods.
Ampliers don’t create energy. The AC mains voltage and current must be sufcient
to deliver the power you expect. You must operate your amplier from an AC mains
power source with not more than a 10% variation above or below the specied line
voltage and within the specied frequency range indicated on the back panel of the
amplier. If you are unsure of the output voltage of your AC mains, please consult
your electrician.
2.8 Protecting Your Speakers
It’s wise to avoid clipping the amplier signal. Not only does clipping sound bad, but
it can damage high-frequency drivers. The built-in clip limiter prevents clipping.
Also, avoid sending strong subsonic signals to the amplier. High-level, low-
frequency signals from breath pops or dropped microphones can blow out drivers.
You can switch to the HI-Z mode which, in addition to switching in the output
transformers for 70V and 100V speakers, activates the high-pass lter. The lter
prevents potentially damaging subsonic signals from going to the amplier by
eliminating signals below 70Hz.
2.9 Startup Procedure
Use the following procedure when rst turning on your amplier:
1. Turn down the level of your audio source.
2. Turn down the level controls of the amplier.
3. Power up the amplier. The blue Power LED should be ON.
4. Turn up the level of your audio source to an optimum level.
5. Turn up the Level controls on the amplier until the desired loudness or power
level is achieved.
If you ever need to make any wiring or installation changes, don’t forget to
disconnect the power cord.
16
3.0 Operation
3.1 Precautions
Your amplier is protected from internal and external faults, but you should still take
the following precautions for optimum performance and safety:
1. Before use, your amplier rst must be congured for proper operation,
including input and output wiring hookup. Improper wiring can result in serious
operating difculties.
For information on wiring and conguration, please consult the Setup section of
this manual.
2. Use care when making connections, selecting signal sources and controlling the
output level.
3. Always be sure to have all levels at minimum when connecting or disconnecting
audio sources from the inputs, especially when MIC is selected from the MIC/
LINE switch. Failure to do so may cause the amplier or speaker to go into a
protection mode or even cause damage.
4. WARNING: Never connect the output to a power supply, battery or power main.
Electrical shock may result.
5. Tampering with the circuitry, or making unauthorized circuit changes may be
hazardous and invalidates all agency listings.
6. Do not operate the amplier with the red Clip LEDs constantly ashing.
7. Do not overdrive the mixer, which will cause clipped signal to be sent to
the amplier. Such signals will be reproduced with extreme accuracy, and
loudspeaker damage may result.
8. Do not operate the amplier with less than the rated load impedance. Due to
the amplier’s output protection, such a conguration may result in premature
clipping and speaker damage.
9. Use the amplier in a well-ventilated environment and do not use it in ambient
temperature conditions in excess of 40°C. Failure to do so will result in the
automatic disconnection from the power supply as the overheat auto protection
function will be activated and there will not be any audio signal coming out
of the amplier. In this case, turn down the volume to the minimum, and the
amplier will soon resume working. When the amplier returns to normal
temperature you may turn the volume up to a safe level.
10. If the line voltage to the amplier is too low, the low voltage protection function
will be activated.
CAUTION: JBL is not liable for damage that results from overdriving other
system components.

3.2 Input Routing
CH1 Settings
MIC
MIC
MIC
The two-channel models, VMA260 and VMA2120,
include a default routing of Input channels 1-3, Music
1 and the Bluetooth/USB source to amplier 1. Input
channels 4-6 and Music 2 are routed to amplier 2.
The user may take any input and have it routed to
both outputs by selecting the appropriate switch. For
example, if you set switch 1 to ON, Input 1 will be
routed to both AMP1 and AMP2.
3.3 Conguration Settings
A DIP switch is available for each output channel to congure the unit to your
specic system.
3.3.1 70V/100V Output Selection
When this switch is in the “OFF” position, the amplier is congured to drive low
impedance speakers, (4 Ohms ,minimum) The 70V/100V switch will activate the builtin output transformer allowing the unit to directly drive 70V or 100V speaker systems
when connected to the appropriate output terminals. As an added feature when
driving the high impedance speakers, the system automatically apply a 70Hz high
pass lter.
3.3.2 Chime Function
Turning chime ON will enable a chime sound
at the onset of an announcement when priority
muting is invoked. (See section 3.5, Priority
Muting, on the following page.)

3.4 VOX Function
Voice activated ducking is available on input channel 2 of the VMA160, VMA1120
and VMA1240. The feature is available for both input channels 2 and 5 of the
VMA260, and VMA2120. The audio input level required to activate ducking is set
using the trim pot on the rear panel. Adjusting in the counterclockwise direction will
reduce that level while the full clockwise setting will disable the VOX function.
3.5 Priority Muting
VMA160, VMA1120 and VMA1240 may use Input channel 2 as a priority channel,
muting all other channels when pins 4 and 5 are shorted using a switch closure.
The VMA260, and VMA2120 lets Input2 operate with priority over all inputs into
output amplier CH1. Similarly, Input5 can exercise priority over all inputs into output
amplier CH2. Input2 will have priority over both ampliers CH1 and CH2 if the
routing DIP switch #2 is set to ON.
3.6 Remote Volume Control
Remote volume control can be implemented using a CSR-V controller connected via
an Ethernet cable to the RJ45 connector on the back panel. For the VMA260 and
VMA2120, there are two connectors, one for each amplier output.
