FIGURE 1. AXU4

1.Power On Indicator: This green light glows when DC Power ia applied to receiver.

2.Diversity A/B Indicators: These yellow lights glow when the receiver detects RF signals from the transmitter. When only one light glows, the signal is being received on only one antenna.

3.Audio Peak Indicator: This red light flickers when the receiver audio output signal approaches the overload clipping level.

4.Volume Control: Increases or decreases receiver output volume. It does not affect audio clipping levels.

5.Antennas: Receive RF signals from the transmitter. For best

performance, point the receiver antennas away from each other at a 45° angle.

6.1/4º Phone Jack Connector (Unbalanced High Z Output):

An unbalanced audio cable with a 1/4º phone plug (such as a

RECEIVER FEATURES

standard guitar cable) can be used between this connector and your amplifier input.

7.XLR Audio Output Connector: Balanced low Z microphone level output.

8.Mic/Line Switch: Switches output of XLR connector from microphone level to line level. Use line level when connecting receiver to a device without an available mic-level input, such as a power amplifier, signal processor, or VCR.

9.Squelch Control: Adjusts squelch to enhance signal quality or extend system range. This control is factory pre-set, and normally does not require further adjustment.

10.Power Input Connector: Mates with the AC power adapter.

11.Power Cable Retainer: Secures the AC adapter cable to the receiver.

1.Power Switch: Turns transmitter power on and off.

2.Input Attenuation Switch: Allows choice between 0 dB and ±20 dB attenuation, for greater audio gain control.

3.Power/Battery Fuel Gauge: The green light indicates the unit is on. The red light indicates less than one hour of battery life remains.

4.Mute Switch: Slide to ON for normal operation. Slide to MUTE to prevent sounds from being picked up by the receiver without turning the transmitter off.

5.Input Connector:Tini Q-G connector allows connection to a variety of lavalier and headset microphone cables and the Shure WA302 instrument adapter cable.

6.Belt Clip: Secures the transmitter to a belt, waistband or guitar strap.

7.Audio Gain Control: Provides audio level adjustment to accommodate various input signal strengths (e.g., speaking into a microphone or playing an instrument). The factory setting is

at mid-point. A small screwdriver is supplied to make adjustments.

8.Antenna: A flexible wire antenna is permanently attached to the bottom of the AXU1 body-pack transmitter. For best operation, the antenna must hang vertically, and should not be coiled or bundled.

9.Battery Compartment: Holds one 9 V battery. Hinged cover opens to provide access to the battery.

10.Lavalier Microphone: Supercardioid WL184 condenser lavalier microphone clips onto a tie, lapel, or acoustic instrument. Includes a Tini Q-G connector.

11.Headset Microphone (WH20TQG): Headset microphone features a headset frame, headband, and an attached Tini Q-G connector. See tag attached to headset for assembly instructions.

12.WA302 Instrument Adapter Cable. Connects output from electric guitar, bass, and other electronic instruments to transmitter input.

1.Power Switch: Recessed to prevent accidental turn-off.

2.Power On Indicator: Glows green when power is on.

3.Low Battery Indicator: Glows red when one hour or less of operating time remains and battery should be changed.

4.Mute Switch: Slide to ON for normal operation. Slide to MUTE to prevent sounds from being transmitted to the receiver. Muting the transmitter does not turn off power.

5.Audio Gain Control: Allows you to adjust the transmitter to match the loudness of your vocals. A small screwdriver is supplied to make adjustments.

6.9V Alkaline Battery (shown installed): Provides power to the microphone-transmitter.

7.Battery Cover: Unscrews for access to the 9V alkaline battery and gain control.

BODYPACK TRANSMITTER SETUP

1.Attach the transmitter to your belt, guitar strap, or waistband as shown in Figure 6. Depress the tab marked PRESS and slip the belt or strap between the transmitter body and the belt clip. For added stability, draw the strap or belt toward the clip's top wire, especially when using thin guitar straps.

FIGURE 6. TRANSMITTER SETUP

2.Plug your guitar, headset microphone, or lavalier microphone into the transmitter.

RECEIVER SETUP

3.Insert a fresh 9V alkaline battery into the battery compartment (A Duracell MN1604 is recommended). A fresh 9V alkaline battery will typically provide 18 hours of performance time. A fully charged 8.4V NiCad battery will provide about 2 hours of performance time.

IMPORTANT: Carbon-zinc and zinc-chloride batteries will not provide adequate power and are not recommended.

4.Replace the battery cover.

HEADSET ASSEMBLY

1.Refer to the tag attached to the headset for assembly instructions. After assembling the WH20, adjust the headband and place it on your head.

2.Position the microphone over the corner of your mouth, about 1/2 inch away. See Figure 5.

3.To reduce pops and breath noise, place the supplied foam windscreen over the microphone.

FIGURE 5. HEADSET MICROPHONE POSITION

1.Plug one end of the AC power adapter into the DC INPUT connector on the back of the receiver.

2.Loop the power cable around the cable retainer on the bottom of the receiver. See Figure 7.

3.Plug the other end of the AC power adapter into an AC power source. The green POWER light on the receiver will glow.
