User manual FENDER SPL-M500

[. . . ] -No user serviceable parts inside, refer servicing to qualified personnel only. Thank you for your purchase of a Fender SPL-M500 Stage Monitor Power Amplifier. We are sure you will find it to be a useful and unique product, providing years of trouble free service in both permanent and portable applications. Although intended primarily for portable stage monitor use, the SPL-M500 is also effective in sound reinforcement applications where fixed microphones are used and feedback is a problem. [. . . ] If the indicator does not light when the power switch is turned on (and does not trip the circuit breaker), check the AC power supply and fuse. DELTACOMPTM SWITCH - This switch activates the internal compressor circuit. This will also "clamp" feedback, helping protect your monitor speakers. During normal operation, keep this switch engaged.

PEAK LED INDICATOR - The red Peak LED Indicator illuminates when the output voltage of the amplifier reaches clipping (maximum output voltage). The threshold for the peak indicator automatically adjusts for load impedance and supply voltage variations. The LED (item F) is illuminated when the amplifier is turned on and main voltage is present. M. PATCH POINT RETURN CONNECTOR Provides the possibility of using the power amplifier by bypassing the preamp section of the unit. When this connector is used, the preamp is totally disconnected from the power amplifier section. If nothing is plugged into this jack, it normally takes its signal from the preamp output, via the PATCH POINT SEND jack. PATCH POINT SEND CONNECTOR - This connection can be used with the patch point return connector, if further signal processing by an external unit is desired. Processing could include the insertion of a 1/3 octave graphic equalizer for tonal shaping, an external compressor/limiter and/or the insertion of an active electronic crossover network for bi-amped monitor systems. The output of this jack is normally tied to the patch point return connector. Using this connector will not disconnect the preamp section from the power amplifier section. BALANCED INPUT CONNECTORS - This unit provides two types of input connectors: a 1/4 inch TRS and an XLR female connector. The 1/4 inch TRS connector polarities are: tip (+), ring (-), and sleeve (ground). The XLR female connector polarities are: pin 2 (+), pin 3 (-), and pin 1 (ground). REAR PANEL J. POWER CORD - The SPL-M500 is equipped with a grounding type supply cord to reduce the possibility of shock hazard. EXTERNAL FUSE - When necessary, replace the external fuse ONLY with one of the same type and rating as shown on the label next to the external fuse holder. [. . . ] Timing of the amplifier's turn-on circuit is usually sufficient to accommodate all the turn-on anomalies from other pieces of gear in a system, making it acceptable to use a single switched power string in a permanent or semi-permanent application. Be sure the AC power source for your AC distribution system has adequate current capability. In multiple amplifier installations, a sequential turn-on (either manually or via timed relays) is recommended to avoid a sudden major drain on the AC line. If you wish to obtain either the optional rear rack ear supports (P/N 040661), please contact your local authorized Fender Pro Audio dealer. AMPLIFIER OPERATION 1. [. . . ]
