Connect the speaker wire to the “70V” output terminal on the amplifier. Then, connect the positive (+) connection to the positive connection on the speaker and “COM” connection to the negative (-) connection on the speaker. Connect the subsequent speakers in parallel to the first speaker - positive to positive and negative to negative - as shown below. SPEAKER TERMINALS The MA30BT offers 3 low impedance outputs: 4Ω, 8Ω, 16Ω. 70V/100V, commercial outputs are also available. PLEASE NOTE: ONLY ONE WIRE SHOULD BE CONNECTED TO THE “COM” SCREW TERMINAL AND ONE WIRE TO THE SELECTED IMPEDANCE OR VOLTAGE SCREW TERMINAL. MULTIPLE COMBINATIONS CANNOT BE DONE AT THE SAME TIME. The low impedance section, 4Ω, 8Ω, and 16Ω, is designed for use with low impedance speakers. The 70V/100V section is designed for multiple speaker distribution. When using the 70V/100V output, the speakers have to be equipped with a 70V/100V transformer. The maximum amount of speakers to be placed on your distribution line is in relation to the power allocated to each speaker. The total wattage (number of speakers x transformer wattage tap) must not exceed the maximum RMS output power of 30W. Failure to do so may cause permanent damage to the amplifier. OPERATION STEPS STARTUP GUIDE • When all connections to the amplifier have been made, turn all volume knobs down. Then, turn the power switch to the on position and the power “ON” LED will illuminate. Turn the “BASS” and “TREBLE” controls to the 12 o’clock position (pointing straight up) and turn the “MASTER” volume knob up slowly. • Make sure a signal is being sent to channels 1, 2, 3, 4 or 5 and gradually increase the volume control for that channel until the output is heard through the speakers. Turn up the “MASTER” to the maximum required volume level and reduce the channel volume control if necessary. • If a microphone is connected to “MIC1” input, make sure it is switched on and, if it requires phantom power, make sure this feature is enabled. Gradually increase its volume control while speaking into the microphone until the required volume level is reached. • If the “Microphone Priority” feature is enabled, audio playback volume through channels 2-5 will be auto- matically reduced when speaking into the microphone. • In addition to the channel and the “MASTER” volume controls, there are “BASS” and “TREBLE” EQ controls to adjust the tone of the overall output. At the 12 o’clock position, these controls are applying no effect to the signal (no boost or cut). Moving the BASS control clockwise boosts low frequencies, moving it counter clockwise will cut low frequencies. Likewise, moving the TREBLE control clockwise boosts the high frequencies, moving it counter clockwise will cut high frequencies. BLUETOOTH • Press the Mode button on the infrared remote to ensure media player is in Blueooth mode, indicated by the letters “BT”. • Go to your device’s settings and find then select device “UP-321B”. No password should be required. • Device should pair within a matter of minutes. • If pairing is unsuccessful, power down your amplifier and close the settings app on your device. • Power up amplifier & reopen settings. Repeat steps 1-3 and attempt to pair again. If you still have issues pairing, please reboot personal device & cycle amplifier power. • Once pairing is successful, open music app. Ensure device volume is turned up to at least 75% capacity on device. • Adjust volume of audio player with volume buttons on infrared remote (OK to set at max volume - 32). • Adjust master volume to desired level, ensuring amplifier does not show clip or show any red lights. USB/SD PLAYBACK • Push a USB thumb drive into the USB port and/or an SD card into the SD card input. • Press the “CD/USB/SD” button to ensure that the player is set to play from the required memory device. • Press the “PLAY/PAUSE” button to play the current track and press again to pause as needed. • Searching and playback of tracks is the same as described above for the CD player. OPERATION STEPS (CONTINUED) FM TUNER Press the FM select button to switch to the FM tuner function. Use the PREVIOUS or NEXT buttons to select a stored channel. Tuning and Storing Stations • Use the “FORWARD/REVERSE” seek buttons to manually select the station. • Alternatively, press and hold the “FORWARD/REVERSE” seek buttons to auto search for available stations. • Upon finding a station, the auto search will stop, giving the option to store this station. • At this point, pressing the “PLAY/PAUSE” button will flash a “00” channel number in the display. • Use the “PREVIOUS/NEXT” buttons to select an appropriate channel memory. • Press “PLAY/PAUSE” again to confirm and store the station into the selected channel memory. • Auto search can be stopped at any time by pressing the “FORWARD/REVERSE” seek buttons. MUTE ON/OFF • Pressing the “MUTE ON/OFF” button will mute the output of the audio player. • Pressing and holding the “MUTE ON/OFF” button will put the audio player in standby mode. • Press this button again to restore functions from standby mode. MUSIC ON HOLD The “MOH OUTPUT” will feed music on your telephone system or PABX. A dedicated input should be available on your telephone system. Please refer to a qualified technician if you cannot identify this input. Outgoing signal should be connected to “COM” and “HOT”. TELEPHONE PAGING INPUT This special “TEL INPUT” will allow you to page into the audio system using a telephone or PABX system. At the end of the announcement, the system will return to its normal operation. The telephone paging input has priority over all other inputs, except for the EMC (fire alarm) input. Final volume adjustment will be made with the “TEL” volume control located on the front panel of the amplifier.
