UHF Handheld Transmitter

KEY FEATURES

The MIPRO handheld wireless microphone is a modular design. It also incorporates proprietary dual squelch to eliminate noise interference.

 Light, rugged housing.

 Distinguished matte silver-gray color

grille.

 Robust bullet-shaped microphone

ensures no impact-damage when dropped.

 Interchangeable microphone capsule

modules are available for replacement and servicing. High dynamic range allows high input level without distortion.

 PLL design ensures transmission

reliability.

 A newly designed recessed power

switch is now located on the upper housing for easier access.

 A set of 10 different color bands is

available to enhance channel identification.

 Efficient transmission, low power

consumption and extremely low handling noise.

PART NAMES AND FUNCTIONS

Grille: Protects microphone capsule and

prevents breathing, wind and POP noises.

Battery Status Indicator: Indicates the power

on/off and battery status.

a. When the power switch is turned ON, the red

indicator flashes briefly and then go out, indicating normal battery status.

b. If no flash occurs, it has either no battery, or the

battery is drained or installed incorrectly.

c. When the power switch is turned ON or during a

live performance, the red indicator stays lit, indicating the battery level is low. A new battery replacement is necessary.

Power On-off Switch: Slide the power switch

to the “ON” position for use or to the “OFF” position when not in use.

Housing: Upper portion that is connected to the

capsule module. Internally it holds the transmitter PCB and battery compartment.

Battery Compartment: Designed to

accommodate two 1.5V(AA) batteries.

Battery Cap: Covers the batteries in the battery

compartment.

Color Coded Protection Ring: Available in

different colors for channel differentiation.

BATTERY INSERTION

(Figure 2)

1. Unscrew battery cap in a counter-clockwise

direction.

2. Insert two 1.5 Volt (AA) batteries into the battery compartment according to the correct polarity as shown in Figure 2. The moment the battery touches the terminals of the compartment, the indicator will flash briefly . This means the polarity is correct. However, if no flash occurs, this indicates wrong insertion or battery is dead. Please re-insert the battery according to its correct polarity or exchange it for fresh batteries. Always change both batteries at the same time.

OPERATING INSTRUCTIONS

When the microphone is switched on the indicator will flash briefly indicating normal operation.

1. Powered-On:

RF signal LED indicator of the receiver illuminates. .

2. After Powered-On:

The number of illuminated LEDs will increase as the signal strength increases. If only the red LED illuminates this indicates abnormal receiving status.

3. During Usage:

The audio LED indicator of the receiver will illuminates according to the sound strength input to the microphone. When the red LED is illuminated, it denotes the maximum sound pressure level is being reached but does not represent distortion.

NOTE: When microphone is not in use make sure the microphone is switched off. If the microphone will not be used for some time, please remove the batteries from the battery compartment to avoid battery leakage which could result in damage to the microphone. If rechargeable batteries are used, remove and recharge when necessary.

CAUTIONS

1. Performer should avoid holding the microphone over or near the antenna section as this will deteriorate transmission efficiency. Severe deterioration if performer directly covers up the antenna section with both hands.

2. Many performers tend to hold the microphone by the top grille. Unfortunately, this position seriously degrades both the sound quality and directionality of a microphone. Even the most expensive microphones will have its original sound quality compromised by this method. Grabbing a microphone by the grille will isolate the capsule's acoustic resonance circuit and or change the capsule resonator's frequency. This results in an inferior performance in both frequency response and the separation of directionality. In addition, a palm's soundfocusing effect will tend to strengthen resonances in certain frequencies and can cause unwanted echo.

3. A proper technique is required for using directional microphones because the distance between the microphone and your mouth has a significant impact on sensitivity and performance. There is an inverse relationship between microphone sensitivity and the distance from the mouth to the microphone. Consequently, performers with a ''weaker'' sound level cannot expect to hold the microphone too far away from their mouth and compensate by turning up the amplifier volume to increase the sound level as this can easily cause echo or feedback. In contrast, performers with a ''louder'' sound level should not hold the microphone too close as this can easily result in distortion by causing the amplifier system to be overloaded.

4. Furthermore, a large-diaphragm directional microphone has a very distinct proximity effect. When the microphone is close to the mouth, the bass response is strengthened as the distance gets closer. Therefore, if a performer's sound is insufficient in bass, they can hold the microphone closer and use the proximity effect to help compensate for the lower bass level. Conversely, if a performer's voice is too heavy in the bass register, increasing the distance between the microphone and their mouth will decrease the proximity effect and reduce the bass response, thus making their voice become clearer and brighter.

5. It is recommended to keep the grille and sponge windscreen clean to avoid any substance blocking the proximity effect of the microphone.

PART NAMES AND FUNCTIONS

4-pin Mini-XLR Connector: Connects to the

MIPRO 4-pin connector. For lavaliere, headset microphone or instrument cable. Allows 5 different input configurations (See the five ways of connection on an AF input connection)

Power Switch: Switch to ON position for

operation. Switch to OFF position when not in use.

Battery Status Indicator: Indicates the power

on/off and battery status.

a. When the power switch is turned ON, the red

indicator flashes briefly and then go out, indicating normal battery status.

b. If no flash occurs, it has either no battery, or

the battery is drained or installed incorrectly.

(Figure 1)

c. When the power switch is turned ON or

during a live performance, the red indicator stays lit, indicating the battery level is low. A new battery replacement is necessary.

Transmitter Housing: Contains the PCB and

battery.

Gain Control: Adjusts the input gain to an

appropriate level.

GT/MT Switch: Switch to the GT position for

electric guitar use ONLY. Gain Control is irrelevant for “GT” mode. Switch to the “MT” position for condenser microphone, wired microphone or Line-in use. Gain Control works in the “MT” mode for input sensitivity adjustments.

Battery Compartment and Cover:

Accommodates two 1.5V(AA) batteries.

Transmitting Antenna: 1/4 wavelength

transmitting antenna.

Detachable Belt Clip: Allows for 360 degrees of

rotating to suite transmitting angles. To detach simply use a screwdriver on a 45 degree angle to unfasten (see Figure 2).

OPERATING INSTRUCTIONS

Select GT/MT Switch position: Determine

the use of the BodyPack transmitter. If a lavaliere or headset microphone will be used the switch should be set in the “MT” position. If a guitar/bass or if used with a line level device (pre amp out) the switch should be set in the “GT” position.

Power On: When powering up the transmitter

switch the power switch to the ON position. The Battery Status indicator will flash briefly indicating normal operational status. When the indicator remains illuminated or does not illuminate at all the battery level is low or exhausted and battery must be replaced for continued operation.

Gain Control : Volume can be adjusted by

the gain control. Gain control has no effect when the switch is in the “GT” position (Guitar).

4-pin Connector: Before making these

connections power down the transmitter to prevent damage to the transmitter, receiver or speaker system. Align and insert the 4-pin plug into the connector accordingly and tighten it in the clockwise direction illustrated in Figure 3. Then power unit up again.
