These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. FCC STATEMENT 1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. 2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. 11. ACCESORIES 12. CAUTION CAUTION: RISK OF EXPLOSION IF THE BATTERY IS REPLACED BY AN INCORRECT TYPE. BATTERY INSTALLATION AND REPLACEMENT MUST BE CARRIED OUT BY PERSONNEL IN POSSESSION OF ENOUGH TECHNICAL KNOWLEDGE, EXPERIENCE OR INSTRUCTIONS TO BE ABLE TO PROPERLY PERFORM THE CONNECTIONS. DONOT USE THIS PRODUCT IN CLOSE PROXIMITY TO WATER. DO NOT USE THIS PRODUCT NEAR ANY HEAT SOURCE AND KEEP IT AWAY FROM NAKED FLAMES. 19 1. IMPORTANT SAFETY INFORMATION 2. FEATURES 3.

Normally, you have the following choices: USB MP3 USB/SD/BT PLAYER CONTROL ELEMENTS Both connectors,1/4” XLR or TRS, can be wired in balanced or unbalanced way, depending on the work necessity. The following ones are examples of how these connectors can bewired: Volume control Channel 1 Volume Control Channel 2 Volume Control Treble Control Bass Control Master Control Battery Status Bar Recharge Indicator Power Indicator Line/Microphone Selector Channel 1 Channel 1 Input Connector Microphone Receiver Mixer Adjusts the level of the microphone signal. Controls the input signal level of channel 1. Controls the input signal level of channel 2. This knob adjusts the gain or attenuation of the channel’s high section at ±10dB. This knob adjusts the gain or attenuation of the bass section of the channel at ±10dB. This control adjusts the overall volume of the mixer and affects ALL channels. This bar of leds indicates the level of the battery charge. This light turns red when the battery needs to be recharged and green when the battery is fully charged. This light will illuminate when the unit has been turned on. This switch changes the impedance of the Line level channel or Microphone level. T…
