CHIAYO ELECTRONICS CO.,LTD

General.

Thank you for choosing Chiayo wireless microphone system !

Our products are designed to last and for user friendly operation.

Each system consists of :

- a receiver

- a handheld or beltpack transmitter

- other necessary accessories

This system has 16 factory preprogrammed frequencies and is ready for immediate use after switch-on. However, all frequency settings can be changed to suit your individual needs, if required.

There are two types of transmitter versions :

The Handheld transmitter ( SQ-1016) is completely wireless microphone itself. It only accepts dynamic or condenser microphone capsule modules which are specially designed by Chiayo.

The Beltpack transmitter ( SM-1016) can accept a wide range of inputs including Uniand Omni-directional lavalier microphone, headset microphone, guitar / instrument input or other line input audio sources.

For more details, please take a few minutes to read this operation manual to have a thorough understanding of the functions and operation of both transmitter and receiver.

7. Turn off the transmitter when not in use. Remove the batteries if the transmitter is not

to be used for a period of time.

8. If the volume Control of the receiver is set too high, it may over-drive the input of the

mixer and cause distortion. Conversely, if the receiver output is set too low, the overall

signal-to-noise ratio of the system may be reduced. Adjust the output level of the

receiver such that highest sound pressure level going into the microphone causes no

input overload in the mixer, and yet permits the mixer level controls to operate in their

normal range (not too high or too low). This provides the optimum signal-to-noise

ratio for the entire system.

Simple DIY trouble shooting:

Case study 1 : Both Transmitter & Receiver are on, but no RF signal received.

Probability 1 :Transmitter and Receiver are having different frequencies.

Solution :Change either Transmitter and Receiver to the same frequency.

Probability 2 :Transmitter is faulty.

Solution :When situation 1 is verified to be correct, then either Transmitter or Receiver

is faulty. To prove this transmitter is faulty, please use another functional

transmitter (if any) of the same model and same frequency to test with the

receiver, If this transmitter with the same frequency could trigger on the

receiver, then this proves that the other transmitter is faulty. Send it back to

Chiayo's authorized agent for service.

Probability 3 :Receiver is faulty

Solution :When situations 1 & 2 failed to bring any result, then the receiver could be

faulty. To verify, please use another functional receiver (if any) of the same

model and same frequency to double check and send it back to Chiayo's

authorized agent for service.

Case study 2 :Transmitter could not be switched on.

Solution :Battery is weak or wrongly installed. If not in this case, please check

according to 1.2 above.

Case study 3 :Strong interference signal received.

Solution :If interference could not be solved by adjusting the squelch (SQ) control to

maximum, please stop using this particular frequency (for a crystal locked

system) and change to another set of a different frequency. For a PLL system,

please switch over to another interference-free channel.

Operation Making changes to various settings on SDR-1932 receiver

Chiayo Transmitters and Receivers have factory preset to allow immediate usage after switch-on.

1. Changing CHANNEL / FREQUENCY

This can only be done by pressing UP or DOWN buttons. After a desired channel is

selected, it will be automatically saved and stored into the memory.

However, please note that the transmitter Sensitivity function is dependent on application such as close proximity singing or tripod mouth speech. To avoid overmodulation and distortion, please check whether the preset sensitivity level is suitable for your particular application. For close proximity singing purposes, please select lowest sensitivity level whereas for tripod mount speech purposes, please select a higher sensitivity level.

2. Adjusting VOLUME level

Volume level can be adjusted by rotating the designated volume knob. Clockwise to

increase the volume and counterclockwise to decrease the volume.

If you have made changes to the setting, after making proper selection on Transmitter and Receiver settings the system is ready for operation. However, both antennas of the receiver must be installed to assure a good reception.

3. Adjusting SQUELCH level

The squelch control is on the back of the receiver. When strong interference happens

to the operation, you can use a small screw driver to increase the squelch level by

turning the switcher clockwise. If the interference is too strong even the level is

already set to maximum, the currently in-use channel is not applicable in this location

and a change to channel is recommended.

First switch on the receiver by pressing the Power On / Off switch. The LED display will show the channel last stored. Then switch on the matching transmitter with the correct matching frequency.

The LED RF indicator on the receiver front panel will light up to indicate RF signal been received. If not in this case, please check and verify the frequency setting on both transmitter and receiver. When transmitter is moving around, the Diversity A B switch will light on alternately to indicate the stronger reception from either A or B antenna.

When voice is spoken into the microphone, the LED AF indicator on the receiver front panel will light on and flash according to the intensity of the AF signal.

Receiver installation

For best operation, the receiver should be at least 1m above the ground and 1m away from a wall or metal surface to minimize reflections. The transmitter should also be at least 1m away from a wall or metal surface to minimize reflections. The transmitter should also be at least 1m away from the receiver.

Keep antennas away from noise source such as motors, automobiles, neon light as well as large metal objects.

There are two different audio outputs at the rear side of the receiver: Balanced ( microphone level) and Unbalanced (LINE leve ). Please select the matching output to match the input of the connecting Mixer or Amplifier.

Tips to obtain the best results for a wireless microphone system

1. For transmitter, please use only fresh alkaline batteries. Do not use general purpose

(carbon zinc) battery.

2. Transmitter and receiver should be as close as possible, but not less than 1m.

3. Position the receiver well so as to minimize possible obstruction between it and the

transmitter. Line of sight is best.

4. If external antenna is used, low loss RF shielded cable should be used and the length

of the cable should not exceed 3m.

5.The receiver antenna should be kept as far away as possible from any metal surface.

6. A receiver can not receive signals from two transmitters at the same time.

There are 2 audio output jacks, AF1 and AF2, in the receiver rear panel. AF1 is for channel 1 while AF2 for channel 2. The audio output of channel 2 can be mixed with channel 1 by switching MIX SWITCH to ON, otherwise its output is independent.

Besides, there is a MIC/LINE selector for both AF1 and AF2. If handheld/headset/ lavalier microphone is used, please switch to MIC. If instrument cable is connected to beltpack transmitter, please switch to LINE.

Battery Installation

SM-1016 uses 2 pieces of " AA " size batteries (Alkaline battery is recommended ).

To install or remove the batteries, press the release buttons(5) at the edges of the transmitter to open or close the cover.

Please remove the batteries if SM-1016 is going to be unused for over a couple of days.

Just place them back to the compartment when you are using it next time.
