Yamaha STAGEPAS 500 - Portable PA System Manual

1. AC IN jack
   Connect the included power cord here.
   
   Be sure to use the included power cord. Use of other cords may result in malfunction, heat generation, or fire.
2. POWER switch
   For turning the power to the mixer on and off.
3. SPEAKERS L/R jacks (for included speakers (500S) only)
   These output the mixed signal channels from 1 to 9/10, and the level is adjusted with the MASTER LEVEL control. Connect only the included speakers (500S).
4. REC OUT L/R jacks
   These output the mixed signal channels from 1 to 9/10, and the level is unaffected by the MASTER LEVEL control. You can use these jacks, for example, to connect to an external recorder.
5. MONITOR OUT L (MONO) /R jacks
   These output the mixed signal channels from 1 to 9/10, and the level is adjusted with the MONITOR OUT control. These jacks are convenient for connecting an external powered speaker for monitoring purposes.
6. Channel input jacks (CH 1 to 4)
   For connecting a guitar, microphone, keyboard or other instrument/device. Set the MIC/LINE switch to MIC or LINE for channels 1 to 4, depending on the level of the input signal. XLR-type connectors are wired as follows (IEC60268 standard): pin 1: ground, pin 2: hot (+), and pin 3: cold (-).
   NOTE: On any given channel, you may use either XLR or phone jack, but not both. Please connect to only one of these jacks on each channel.
7. Stereo channel input jacks (CH 5/6, 7/8, 9/10)
   Input the left and right channels of a stereo signal into the respective odd and even channels of the mixer. These inputs are intended mainly for use with instruments and equipment having stereo outputs, such as a synthesizer or CD player.
   NOTE: The channel 7/8 input provides two sets of jacks—both phone jacks and RCA-pin jacks. Either one of these jacks may be used, but not both at the same time. Please connect to only one of these jacks on each channel.
8. MIC/LINE switch
   Set this switch to MIC or LINE for channels 1 to 4, depending on the level of the input signal. For low-level signals (such as that of microphones), set the switch to the MIC () position. For high-level signals (such as keyboard instruments and audio equipment), set the switch to the LINE () position.
   
   To avoid damage to speakers, be sure to turn off amplifiers (or powered speakers) before setting this switch to MIC or LINE. We also recommend that you turn the MASTER LEVEL control to the minimum setting before operating the switch, to avoid excessively loud noises that could cause hearing loss or device damage.
9. PHANTOM switch
   If you set the switch on, the mixer supplies phantom power on to the XLR mic input jacks on the channels 1 to 4.
   
   • Be sure to leave this switch OFF if the device or instrument that you are using does not require phantom power.
   • When using phantom power, do not connect any devices other than condenser microphones to the XLR input jacks. Other devices may be damaged if connected to phantom power. This precaution does not apply to balanced dynamic microphones, however, as these will not be affected by phantom power.
   • To avoid damage to speakers, be sure to turn off amplifiers (or powered speakers) before turning this switch on or off. We also recommend that you turn the MASTER LEVEL control to the minimum setting before operating the switch, to avoid excessively loud noises that could cause hearing loss or device damage.
10. LIMIT/COMP switch
    Set this switch to COMP () to apply compression, or set it to LIMIT () to apply limiting. By compressing excessive peaks of input signals and bringing up the level of overly soft parts, compression raises the overall volume without introducing distortion. Compression can be used to make a mix sound louder and have more punch. The Limiter is used to suppress excessive input signals and bring them down to an adequate level. The switch lights up in yellow when it is set to COMP ().
11. Equalizer
    HIGH: Determines the level of the high frequency band for each channel. Rotating the knob clockwise boosts the high frequencies and produces a clearer, crisper sound. If you start getting feedback (a high-pitched squealing sound) or you want to make the sound softer and less harsh, turn the knob counterclockwise slightly.
    LOW: Determines the level of the low frequency band for each channel. Rotating the knob clockwise boosts the low frequencies and produces a deeper, warmer sound. If you start getting feedback or you want to make the sound less boomy, turn the knob counterclockwise slightly.
12. REVERB switch
    Set this switch to ON to recreate the rich ambience of various performance environments, such as a concert hall or a night club. The switch lights up in green when REVERB is ON ().
13. REVERB control
    Determines the overall level of the reverb or echo that is applied to the output signal. For best results, this level should not be set very high, to avoid possible feedback and to prevent the sound from becoming "muddy" with too much reverb.
14. LEVEL control
    Use these controls to adjust the volume balance among the various channels.
    
    To reduce noise, set any LEVEL controls on unused channels to the minimum.
15. MASTER LEVEL Control
    Determines the volume of the signal output from the SPEAKERS L/R jacks. This allows you to adjust the overall volume without changing the relative volume balance among the various channels (made with the LEVEL controls) or the tone settings (made with the Equalizer).
16. SPEECH/MUSIC switch
    Set this switch to SPEECH ( ) to optimize the mixer settings and sound quality for speech purposes and announcements. Set this to MUSIC () to optimize the mixer for musical performance. The switch lights up in yellow when it is set to MUSIC ().
17. MONITOR OUT Control
    Determines the signal level output from the MONITOR OUT jacks.
    NOTE: The MASTER LEVEL Control does not affect the signal via the MONITOR OUT Control.

10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
    
    
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR MOISTURE.

Water warning

• Do not expose the device to rain, use it near water or in damp or wet conditions, or place containers on it containing liquids which might spill into any openings.
• Never insert or remove an electric plug with wet hands.

If you notice any abnormality

• If this device should be dropped or damaged, immediately turn off the power switch, disconnect the electric plug from the outlet, and have the device inspected by qualified Yamaha service personnel.

Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the device or other property. These precautions include, but are not limited to, the following:

Power supply/Power cord

• Remove the electric plug from the outlet when the device is not to be used for extended periods of time, or during electrical storms.
• When removing the electric plug from the device or an outlet, always hold the plug itself and not the cord. Pulling by the cord can damage it.

Location

• When transporting or moving the device, always use two or more people. Attempting to lift the device by yourself may damage your back, result in other injury, or cause damage to the device itself.
• Before moving the device, remove all connected cables.
• When setting up the device, make sure that the AC outlet you are using is easily accessible. If some trouble or malfunction occurs, immediately turn off the power switch and disconnect the plug from the outlet.
• Do not use the device in a confined, poorly-ventilated location. Make sure that there is adequate space between the mixer and surrounding walls or other devices: at least 30 cm at the sides, 30 cm behind and 30 cm above. If the mixer is to be used installed into the speaker cabinet, make sure to allow adequate space between the speaker and the surrounding walls or other devices: at least 30 cm at the sides, 30 cm behind and 30 cm above. Inadequate ventilation can result in overheating, possibly causing damage to the device(s), or even fire.
• Do not use the speaker's handles for suspended installation. Doing so can result in damage or injury.
• Avoid setting all equalizer controls and faders to their maximum. Depending on the condition of the connected devices, doing so may cause feedback and may damage the speakers.
• Do not expose the device to excessive dust or vibrations, or extreme cold or heat (such as in direct sunlight, near a heater, or in a car during the day) to prevent the possibility of panel disfiguration or damage to the internal components.
• Do not place the device in an unstable position where it might accidentally fall over.
• Do not block the vents. This mixer has ventilation holes at the top to prevent the internal temperature from becoming too high. In particular, do not place the device on its side or upside down. Inadequate ventilation can result in overheating, possibly causing damage to the device(s), or even fire.
• Do not use the device in the vicinity of a TV, radio, stereo equipment, mobile phone, or other electric devices. Doing so may result in noise, both in the device itself and in the TV or radio next to it.

Connections

• Before connecting the device to other devices, turn off the power for all devices. Before turning the power on or off for all devices, set all volume levels to minimum.
• For the SPEAKERS jacks, Use only the included speakers (500S) and speaker cables. Use of other types of speakers and cables may result in damage to the device(s), or even fire.

Handling caution

• When turning on the AC power in your audio system, always turn on the device LAST, to avoid speaker damage. When turning the power off, the device should be turned off FIRST for the same reason.
• Do not insert your fingers or hands in any gaps or openings on the device (vents,, ports, etc.).
• Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any gaps or openings on the device (vents, ports, etc.) If this happens, turn off the power immediately and unplug the power cord from the AC outlet. Then have the device inspected by qualified Yamaha service personnel.
• Do not use the device for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician.
• Do not operate the device if the sound is distorting. Prolonged use in this condition could cause overheating and result in fire.
• Do not rest your weight on the device or place heavy objects on it, and avoid use excessive force on the buttons, switches or connectors.

Protective Circuit (poly switch)
All full-range loudspeakers are fitted with a self-resetting poly switch that protects the high-frequency driver from damage caused by excessive power. If a loudspeaker cabinet loses high-frequency output, immediately remove power from the unit and wait for two to three minutes. This should be long enough to allow the poly switch to reset. Reapply power and check the performance of the high frequency driver before continuing, with the power reduced to a level that does not cause the poly switch to interrupt the signal.

Interference From Cell Phones
Using a cell phone near the speaker system can induce noise. If this occurs, move the cell phone further away from the speaker system. Air blowing out of the bass reflex ports is normal, and often occurs when the speaker is handling program material with heavy bass content.
Yamaha cannot be held responsible for damage caused by improper use or modifications to the device.
Always turn the power off when the device is not in use. The performance of components with moving contacts, such as switches, volume controls, and connectors, deteriorates over time. Consult qualified Yamaha service personnel about replacing defective components.
