[. . . ] A500 Users manual Version 1. 0 March 2005 REFERENCE AMPLIFIER ENGLISH REFERENCE AMPLIFIER A500 IMPORTANT SAFETY INSTRUCTIONS DETAILED SAFETY INSTRUCTIONS: 1) Read these instructions. CAUTION: To reduce the risk of electric shock, do not remove the top cover (or the rear section). No user serviceable parts inside; refer servicing to qualified personnel. 5) Do not use this apparatus near water. [. . . ] Due to safety considerations, the inputs can not be used in parallel. However, if you are using cinch and XLR or 1/4" TRS connectors simultaneously, the cinch input is given preference, and the other signal is muted. If you wish to use the A500 in mono-bridged mode, please only use one of the channel 1 inputs!The STEREO/BRIDGED MONO switch is used to toggle between the two operating modes of your A500. Please power the A500 down using the POWER switch each time you change the operating mode. Similarly, only connect/disconnect speaker connectors if the A500 has first been powered off!OUTPUT 1, OUTPUT 2 and BRIDGED MONO: These are the speaker connectors of your A500 laid out as 1/4" TS mono connectors. When in mono-bridged mode, only use the BRIDGED MONO output. Keep in mind the minimum power impedance of 4 Ohms per channel in stereo mode. When in monobridged mode, a loudspeaker whose impedance is at least 8 Ohms must be used. In addition to XLR or 1/4" TRS connectors, you can also use binding posts for connecting speaker cables. When in mono-bridged mode, make sure to connect your cables to both middle connectorsas shown on the unit itself. Before connecting the unit to the mains, please check if the voltage selector corresponds to your local voltage. When replacing fuses, you should only use fuses of the same type and rating. With some units, the fuse switch can be put into two different positions in order to select between 230 V and 120 V operation. Please bear in mind: If you wish to use your equipment outside of Europe running on 120 V, you will have to use a fuse with a higher Ampere value. The mains connection is made via a standard IEC RECEPTACLE. SERIAL NUMBER. + + + + 6 2. CONTROL ELEMENTS REFERENCE AMPLIFIER A500 3.
