Page 5 of 20 VENTILATION AND HEAT SINK The heatsink and cooling fans are provided to ensure reliable operation of the loudspeaker, and to protect it from overheating. The heatsink and fans must not be blocked or covered. This product should only be installed with adequate ventilation around the rear of the unit. WATER AND MOISTURE Do not use this product anywhere near water, or place any liquid-containing-vessels near to the unit where spillage could occur.
Page 6 of 20 IMPORTANT: Always connect the product to the mains using the blue PowerCON MAINS IN connector. IMPORTANT: Only connect additional products to the white PowerCON MAINS LINK connector, keeping within the specified current rating. IMPORTANT: When disconnecting this product from mains power, always disconnect the mains end first before disconnecting the PowerCON connector. Similarly, when connecting this product always connect to the loudspeaker first, before applying mains power at the supply.
Page 7 of 20 1.0 - Introduction Thank you for purchasing the MSE-218SP self-powered subwoofer from EM Acoustics. The MSE-218SP has been designed and rigorously tested to give you the utmost in sonic performance and many years of reliable, trouble-free operation. Please take the time to read this user manual thoroughly to ensure you get the best performance from your system and to ensure you set it up correctly and safely.
Page 8 of 20 2.0 – The MSE-218SP Subwoofer The MSE-218SP is the self-powered variant of the MSE-218 loudspeaker, and as such follows all the same principles in design and operation. The MSE-218SP is designed to be a reliable, rugged subwoofer that will stand up to the rigours of use both in fixed installations and touring applications. The reflex design utilizes a pair of powerful 4.5” voice coil 18” (457mm) neodymium LF drive units in an incredibly rigid and rugged enclosure.
Page 9 of 20 3.0 – Mains Power Requirements 3.1 - Power Supply The MSE-218SP utilises a pair of UMACTM Class-D amplifier modules with a Power Factor Correction (PFC) power supply, ensuring universal mains voltage operation. The amplifier modules can safely operate with voltage ranges from 100-120VAC and 200-240VAC. Important Note – please be aware that using these products on 100-120VAC will draw more current from the mains supply than using at 200-240VAC. 3.
Page 10 of 20 3.5 - Powering up the MSE-218SP When mains power is supplied, the power supply automatically detects the supply voltage and adjusts itself accordingly. Once the display has gone through the “initializing” stage, the screen will show the unit name and current preset recalled, and is then ready for use. Important Note: When connecting the MSE-218SP to mains power supplies, always connect the PowerCON first, and then connect to the mains supply.
Page 11 of 20 4.0 – Amplification and Audio The MSE-218SP includes a highly advanced 64-bit DSP processing card to handle high & low pass pass filters, gain and delay settings, which are accessed by means of preset programs that are factory installed into the unit. This DSP card feeds a pair of Class-D amplifier modules (one module per drive unit) providing ample power to drive your loudspeakers to their full potential. The amplifier and DSP combination also provides full limiting and remote monitoring.
Page 12 of 20 4.2 - Linking multiple loudspeaker audio signals Via the male output XLR, multiple loudspeakers can be linked together on the same signal. With the digital input stage selected, the output is internally buffered so in essence an infinite number of units can be connected in parallel without signal degradation. In analogue mode, ensure that the source device can drive the combined impedance of all of the connected loudspeakers.
Page 13 of 20 ACCESS LEVEL – Administrators can choose to lock all functions on the amplifier modules by entering the relevant password – please contact EM Acoustics for further details on this function. VERSION INFO – by pressing the Edit encoder repeatedly, the unit will step through user information such as software version, hardware version, IP address and MAC address. 4.3.3 – EXIT Key The exit key takes you one step back in the menu system from wherever you are for each press of the key.
Page 14 of 20 5.0 – MSE-218 subwoofers in use 5.1 - System Overview MSE-218SP subwoofers can be used either in landscape or portrait format, depending on space requirements. Landscape format is recommended as the touring skids on the underneath will protect the cabinet finish, and the stacking recesses can be used to add extra stability when stacking multiple units. 5.
Page 15 of 20 To use the M20 threaded flange adapters, use a telescopic distance pole such as the EM Acoustics DP-01. Screw the threaded end into the flange adapter, making sure it is screwed in completely. Then, carefully lift the fullrange loudspeaker onto the pole. 6.0 - Servicing Information Your EM Acoustics loudspeakers have been rigorously tested before they leave our factory, to ensure that they give you a lifetime of flawless operation.
