[. . . ] 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. 8) Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. [. . . ] Because these inputs are more sensitive than others, you can directly connect a CD player or a DAT recorder. Of course this input can also be used for connecting mixing consoles and similar equipment. The XLR and 1/4" TRS stereo connectors are laid out balanced, but they too can of course be used to connect unbalanced signals. Generally speaking, you should choose balanced over unbalanced signals in order to guarantee the highest noise protection. 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. 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. APPLICATION EXAMPLES 3. 1 Stereo mode In this mode, both channels run independently with a separate input signal. Connect passive loudspeakers, preferably highquality studio monitors, such as the BEHRINGER TRUTH B2031P. Please only connect the speaker using the BRIDGED MONO connector or by using both of the middle binding posts . + + Always power the A500 down using the POWER switch whenever you make any changes to the operating mode settings. Keep in mind the minimum load impedance of 8 Ohms in mono-bridged mode. + + Please use the POWER switch to power down your A500 before making any changes to the operating mode settings.
