Maselec MEA-2 FAQ, Tips and Techniques

General FAQs
?	How should the interconnecting cables be wired?
	Answer: This unit can be used with either balanced or unbalanced input and output on standard XLR connectors. All XLR connections should use a good quality screened twisted pair cable with the screen connected to pin 1 of the connector at both ends. Please refer to section 5 of the Operation Manual for further pin connection details. The manual can be downloaded from the downloads page.
?	How do I know whether the equalizer is in circuit?
	Answer: The relevant in/out push button is illuminated a soft blue colour when the equalizer is in circuit.
?	The unit appears dead.
	Answer: Check that the rear-mounted mains switch is in the `ON` position (its integral lamp should illuminate) and that the front panel switch is operated. Check the mains fuse, accessible from the rear in the IEC mains inlet. The correct type is a 20mm 250V 315mA T (anti-surge slow).
?	I am only getting +22dBu maximum output instead of the claimed +28dBu.
	Answer: When using unbalanced connections, the maximum input and output are reduced by approximately 6dB from the nominal +28dBu.
?	How do I use this unit on a different mains supply?
	Answer: Disconnect the unit from the mains. Find the mains (line) voltage selector switch on the rear panel, and using a small screwdriver or similar tool, slide it to the required voltage setting. The `115` setting is for voltages from 90-130 V AC and the `230` setting is for voltages from 180-260 V AC. This unit works equally well from both 50Hz and 60Hz supplies.
?	Do I need to earth the chassis separately using the earth stud at the rear?
	Answer: The unit has an internal link connecting the audio ground (0V) to chassis, so you will not normally need to use the earth stud.
