Some receivers are equipped with IrDA 2-ways synchronization.

Configuration

STAGE PRO / STAGE MAN may come equipped with the following:

1. AC power cord

2. 1~4 or no wireless receiver/transmitter/MP3/Bluetooth module(s).

3. 1~4 transmitters, either handheld or belt-pack transmitter (except version with no module installed).

Optional accessories

1. Weather proof dust cover.

2. Single trolley bag/Dual trolley case

Parts and functions on STAGE SPEAKER control panel

1. Audio input

Starting to operate the STAGE PRO / STAGE MAN

First of all, please charge the system for at least 4~6 hours after unpacking because the built-in rechargeable battery might have lost some of its charges naturally due to long shipment and storage time, even though it has been fully charged in the factory before shipment.

To operate this portable sound unit, please switch on the main POWER switch. However, if the battery indicator stops at 40%, it means that the battery is getting weak and instant charging is necessary.

The main POWER switch / Volume does NOT automatically switch on the other devices (modules) since each of them has individual Power/Volume control. To operate those, you have to switch them on accordingly.

Operating the wired microphone

To use a cable microphone, simply plug it into any MIC IN socket. The combo sockets accept either XLR or 6.3mm jack. There are individual volume / tone and reverb controls for both microphones.

Playing the instruments (for STAGE PRO only)

There are 2 inputs for connection with your instrument such as guitar. Above them is the dedicated volume control.

Music audio inputs

To receive different audio signals from unbalanced sources with different connectors, the unit is equipped with one 3.5mm and one RCA R/L (STAGE PRO only) jacks. This Line-in area has its individual volume and tone control (Bass/Middle/Treble), too.

Digital in (STAGE PRO only)

The Digital-in is for audio connection with the PC/Notebook. Just use a USB cable to connect the unit and your PC/Notebook to make STAGE PRO the speaker of your device. Its volume is controlled by the master adjusting knob.

Operating Voice Priority (STAGE PRO only)

Voice Priority operation is only necessary when CD/USB/MP3 is playing. When the Voice Priority switch is ON, the ducking function will be activated. While the music is playing, a voice input from either a Wired or Wireless Microphone will temporarily override and lower the volume of the background music and voice could be heard more clearly.

Background music will return to its original setting when no audio input is entering the microphone for a certain time. However, if the microphone is not switch off, the reentering of music into the microphone will also activate the voice priority function.

Operating Loudness (STAGE PRO only)

When the amplifier’s sound is at low level, the tone might not be heard clearly and activating the Loudness function can raise the tone level to make it clearer.

Limiter Function

There’s an interior anti-overload circuit to protect the amplifier from being damaged due to over volume output, this design will automatically lower the output when it goes over the limit.

Various audio outputs

Active out: STAGE PRO could be operated as the MASTER unit in an audio link (wired) configuration. The Master is capable of daisy chain manner wire connecting of up to about 20 active speakers (Stage Slave).

To install the link, connect the output jack of the Master to the Active IN of the 1st STAGESLAVE. Its Output jack should be connected to the Active-in of the 2nd Stage Slave and so forth.

Aux out: This 6.3mm jack is used as audio output connection to another active amplifier.

Charging the battery

STAGE PRO/ STAGE MAN uses either two lead-acid batteries or one lithium battery. The battery power is leveled from 40%, 60%, 80% and FULL. If the LED stays at 40%, the battery might not be sustainable for long operation. During recharging the indicator LED will flash RED until the battery power is full, at which the LED changes to GREEN. However, if there is no battery inside or the battery has problem, the charging LED will stays YELLOW.

Operating the wireless microphone

To operate the wireless system, please switch on the power/volume control on the receiver module panel and the matching transmitter. Then set the channel on both the transmitter and receiver module to the same before operation. Please also make sure that master volume control is set to minimum level before turning on the amplifier, especially working on a wireless version! Position the Master volume to the middle. Then adjust the receiver volume to a desired level and the operation is ready.

SQUELCH (SQ) setting

When a channel is in use and undesired interference signal is received, turn the SQ in clockwise direction to make the receiver less sensitive and thus less susceptible to interference. If this still does not solve the problem, it means this frequency is not applicable at current position. Please switch over to the next channel.

Channel synchronizing of the receiver and transmitter

1. To achieve a trouble-free synchronization, please limit the distance between the receiver and transmitter to within 30cm.

2. Align both sensor areas

3. To change the receiver’s channel, please press the synchronizing button of the transmitter. The transmitter will transmit synchronizing signal to the receiver and change its channel.

4. To change the transmitter’s channel, please press the synchronizing button of the receiver. The receiver will transmit synchronizing signal to the transmitter and change its channel.

5. Unit GAIN control: This controls the GAIN level of internal audio output.

6. 3.5mm audio input jack

7. AUX IN GAIN control: This controls the GAIN level of external audio input.

8. Output power setting: LOW (left) for Low output power and HI (right) for high output power. Low output power will reduce the RF transmission distance and High output power will extend the possible RF transmission distance. However, if the module is installed on batterypowered amplifiers, HIGH output power would reduce battery operating hour than LOW output power since it requires more power for stronger RF transmission.

Maintenance-free Lead Acid battery

Guidelines for maintenance-free Batteries:

1. Battery should operate at temperatures between 15°C ~ 50°C. To ensure a longer life span, it should be kept between 5°C ~ 35°C. For optimum result, 20°C ~ 25°C will be ideal. When temperature falls 15 degrees below zero, battery will undergo some changes in its chemical contents and therefore cannot be recharged. Operating the battery at higher temperature will result in higher capacity but shorter lifespan, whereas lower temperatures operation has a longer lifespan but less capacity.

2. If the battery is not recharged 72 hrs after it is completely used, it will be permanently damaged.

3. When the battery is being charged, the internal gases will be electrolyzed into water at the negative charge, maintaining the battery’s storage abilities with no water added. However, erosion at the charged ends of the battery will cause poor performance.

4. The battery’s cycle lifespan (no. of charge and discharge cycle) is determined by the degree at which power is dissipated, especially the degree of discharged each time it is used and the recovery charging method. For normal use, the battery can be used for longer hours when less power is dissipated each time and vice versa. At 25°C, maintenance-free batteries could be charged 150 ~ 200 times at 100% discharge each time.

5. Decrease in capacity, internal short circuit, deformation in appearance, erosion of charged ends and decrease in open circuit voltage are symbols indicating battery is approaching the end of its life cycle.

6. When two batteries are used in parallel connection, the resistance of the cables should be kept equal.

Properties of the Lead Acid Battery:

1. Has no memory effect. Can be charged anytime, even when the recharge indication light is off.

2. Performance and efficiency are affected by changes in the environment, especially temperature and humidity. (Best operated between 20°C ~ 25°C)

3. Battery discharge naturally according to a certain pattern even not in use. For best performance and a prolonged lifespan, it should be recharged every month even when not in use.

4. Under normal circumstances, battery could last for about a year.

5. When the battery’s life expires, possible indicators include internal short-circuit, decrease in capacity, deformation in appearance, erosion of charged ends and decrease in operating voltage.

User’s Precautions:

1. For first-time use, charge the battery for 10 hrs until it is fully charged.

2. To maintain performance and lifespan, if product has not been used for 3 months after the initial shipment, please fully charge the battery.

3. Before each use, it’s advisable to charge the battery to its full capacity.

4. The average lifespan of the battery is one year. The user is advised to change the battery after one year of use.

5. The current consumption is in direct ratio with load current. The more current consumption, the less the operation time.

6. Warranty will be void if the battery is not charged for a prolong period as it may lose all its charge and could never be recovered again.
