Frequently Asked Questions - VMA160 JBL

Why is there no power and the LED is off?

Ensure the unit is plugged into a working AC outlet and the power switch on the front panel is turned on. Check the IEC power cord connection at the rear panel.

No sound or very low sound from the speakers.

Verify that the audio source is active and the input level controls on the front panel are turned up. Also check the Master Volume control. If a CSR-V remote is connected, ensure it is not turned down. Ensure the 70V/100V output switch is ON if using high-impedance speakers. Check if a priority mute (PTT) is engaged.

Sound is distorted.

Reduce the input level controls or the Master Volume to avoid clipping (the red ring around the Master Volume should not stay lit). Ensure the MIC/LINE switch is set correctly for your source (MIC for microphones, LINE for line-level devices). If the switch is in MIC position with a line source, distortion may occur.

How do I pair a Bluetooth device?

Press the Bluetooth key on the front panel until the Bluetooth indicator flashes. On your source device, search for 'JBL COMMERCIAL (XX)' (where XX are the last two digits of the MAC address). Select it to pair. Once connected, the indicator stops flashing and stays lit. The Bluetooth signal is muted during chime tones.

How do I play music from a USB drive?

Insert a USB drive into the USB port on the front panel. The number of folders and files will be displayed. Use the PREVIOUS/NEXT keys to scroll through media, VOLUME UP/DOWN to adjust volume, and PLAY/PAUSE to start or pause playback. Repeat modes are available via the REPEAT key.

How does priority muting work?

Input 2 (on single-channel models) can be set as a priority channel. When pins 4 and 5 of the Euroblock connector are shorted (via a switch), all other inputs are muted. On two-channel models, Input 2 prioritizes CH1 and Input 5 prioritizes CH2. The chime can be enabled to sound at the start of a priority announcement.

What is the VOX function and how do I adjust it?

VOX (voice-activated ducking) reduces the level of other channels when audio is detected on Input 1. The sensitivity is adjusted via a trim pot on the rear panel. Turn clockwise to require a higher input level to trigger ducking; fully clockwise disables VOX. This is useful for paging over background music.

Can I control the volume remotely?

Yes, connect a JBL CSR-V remote control module to the RJ45 jack on the rear panel using a CAT5 cable. This allows remote adjustment of the output volume. The CSR-V can be placed at a convenient location.

How do I update the firmware?

Place the firmware file ('.mcs') on a blank USB drive. Insert the USB drive into the front port. The display will show 'USB UPGRADE'. Wait until it shows 'USB SUCCESS' and the display turns off. Power off the unit, remove the USB drive, then power on again. The upgrade is complete.

What is the warranty coverage?

The VMA160 comes with a 3-year warranty valid within the United States. For warranty outside the USA, contact your local JBL distributor. The warranty does not cover damage from improper use or unauthorized modifications.

2.0 Setup

2.1 Unpacking Your Amplifier

Please unpack and inspect your amplifier for any damage that may have occurred during transit. If damage is found, notify the transportation company immediately. Only you can initiate a claim for shipping damage. We will be happy to help as needed. Save the shipping carton as evidence of damage for the shipper's inspection.

We also recommend that you save all packing materials so you will have them if you ever need to transport the unit. Never ship the unit without the factory pack.

WARNING: Before you start to set up your amplifier, make sure you read and observe the Important Safety Instructions found at the beginning of this manual.

2.2 Installing Your Amplifier

CAUTION: Before you begin, make sure your amplifier is disconnected from the power source and all level controls turned completely down (counterclockwise).

Note: We recommend that any sensitive equipment be located at least 8 inches (20 cm) away from the amplifier.

To install the amplifier, you can use one of the following approaches:

- Rack mount the amplifier with the rack mounting kit, see Figure 2.2.2.

- Place a single amplifier on a surface with 12 inches of air space around the unit for convection cooling. Rubber feet are included and can be attached onto the underside of the chassis. For amplifier dimensions, see Figure 2.2.1.

Figure 2.2.3 Rack Mounting the Mixer-Amplifier

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 amplifier using the screws provided.

2. Attach the rear flat brackets to each side of the rear of the amplifier 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 flat brackets, attach them each using a screw passing through two washers, the rear flat bracket and the rear angle bracket as shown in the figure.

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 amplifier 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 amplifier 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 qualified personnel.

Figure 2.4.1 Input Wiring

NOTE: Two RCA connectors are provided for summing left and right channels from a stereo source. Do not use both Euroblock and RCA connectors concurrently for any single input channel.

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 amplifier 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 amplifier output connector. The minimum impedance an amplifier 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 amplifier 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 amplifier 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.

2.7 Connecting to AC Mains

Connect your amplifier 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 amplifier; 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.

Amplifiers don't create energy. The AC mains voltage and current must be sufficient to deliver the power you expect. You must operate your amplifier from an AC mains power source with not more than a 10% variation above or below the specified line voltage and within the specified frequency range indicated on the back panel of the amplifier. 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 amplifier 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 amplifier. 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 filter. The filter prevents potentially damaging subsonic signals from going to the amplifier by eliminating signals below 70Hz.

2.9 Startup Procedure

Use the following procedure when first turning on your amplifier:

1. Turn down the level of your audio source.
2. Turn down the level controls of the amplifier.
3. Power up the amplifier. 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 amplifier 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.

3.0 Operation

3.1 Precautions

Your amplifier is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety:

1. Before use, your amplifier first must be configured for proper operation, including input and output wiring hookup. Improper wiring can result in serious operating difficulties.
   For information on wiring and configuration, 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 amplifier 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 amplifier with the red Clip LEDs constantly flashing.
7. Do not overdrive the mixer, which will cause clipped signal to be sent to the amplifier. Such signals will be reproduced with extreme accuracy, and loudspeaker damage may result.
8. Do not operate the amplifier with less than the rated load impedance. Due to the amplifier's output protection, such a configuration may result in premature clipping and speaker damage.
9. Use the amplifier 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 amplifier. In this case, turn down the volume to the minimum, and the amplifier will soon resume working. When the amplifier returns to normal temperature you may turn the volume up to a safe level.
10. If the line voltage to the amplifier 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

The two-channel models, VMA260 and VMA2120, include a default routing of Input channels 1-3, Music 1 and the Bluetooth/USB source to amplifier 1. Input channels 4-6 and Music 2 are routed to amplifier 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 Configuration Settings

A DIP switch is available for each output channel to configure the unit to your specific system.

3.3.1 70V/100V Output Selection

When this switch is in the "OFF" position, the amplifier is configured to drive low impedance speakers, (4 Ohms ,minimum) The 70V/100V switch will activate the built-in 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 filter.

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.)

3.3.3 Line/Mic Gain Switch

Additional gain is available for use with sources, in particular microphones, that have low output levels. Switching to MIC position activates 48dB additional gain. Use only when necessary as the added gain may cause higher noise levels.

3.3.4 Phantom Power

Phantom power (27V) can be applied to specific mic inputs by turning on the appropriate Phantom Power switch.

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 amplifier CH1. Similarly, Input5 can exercise priority over all inputs into output amplifier CH2. Input2 will have priority over both amplifiers 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 a CAT5 cable to the RJ45 connector on the back panel. For the VMA260 and VMA2120, there are two connectors, one for each amplifier output.
