[. . . ] PORTABLE SOUND SYSTEMS From Fender Pro Audio Owner's Manual for Passport - 150 P/N 000000 REV A A Message from the Chairman At Fender, we know the importance of sound reinforcement. From the simple box-top powered mixer to today's touring concert systems, the need to communicate to make the connection between the performer and the audience is foremost in our mind. Perhaps no other piece of gear can make or break your message or your band's sound than your sound reinforcement gear. Your sound system is far more than just a combination of dials, wires and speakers. [. . . ] This three pin XLR balanced female input connector is intended for input signals from low impedance microphones. This 1/4 inch balanced input jack suited for use with items having a line level output such as high impedance microphones, keyboards, drum machines, outboard effects, etc. STEREO / MONO SWITCH - This switch allows E the user to select between a stereo or mono inputs items F H and G. This switch should be F set to the Mono position when a source such as a guitar is input to this channel, thus allowing the mono source to be applied to both outputs at the same level. Failure to do G this will result in the input source only appearing at one of the outputs. When the switch is in the stereo position, the full stereo field is heard. TAPE IN - Balanced phono (RCA) input jacks designed for use with a tape player, CD player, etc. These jacks are stereo and the full stereo field will be heard when playing prerecorded music. STEREO - This 1/4" jack is wired for Tip=Left, Ring=Right and Sleeve=Ground, the standard format of commercially available cables. The sensitivity of this input is suited for playback devices such as CDs, Cassettes, DAT or Mini Disc. Outputs from instruments such as keyboards can also be used here (refer to item E). TAPE OUT - The two Tape Out RCA jacks provide a mix output that is independent of the Master Level Controls. Connect these to the inputs of a recording device, such as a cassette or DAT recorder, to record your event. Changes made during the performance, to the input level controls, channel EQ, and reverb controls will be heard in the Tape Out mix. Changes made to the master level controls will not effect the level of the recording. Adjust recording levels according to the instructions on your recording device. D D. 3) - Input 3 features a pair of RCA input connectors that allow an additional line level stereo source to be input to the system. These connectors SUM, or add, the two input signals together and send them to the mix in exactly the same way as the normal Line inputs. Note: These connectors are set at a constant "line level" are not effected by the Mic/Line "gain" select switch. 9 AUX / FOOTSWITCH JACKS A. Although the Passport is already equipped with on-board digital reverb, an external effects signal processor can be incorporated into the Passport's signal flow. This 1/4 inch output jack is designed to feed the Passport's effects bus signal to an external signal processing device, such as a digital delay or a chorus unit. AUX RETURN - Plug your external effects signal processor's output signal in here. [. . . ] For example: a person holding a microphone close to their mouth and talking/singing even at a medium level, inputs literally hundreds of times more signal power than one using the mic at a distance of one meter (three feet). The resultant difference in control settings between these two examples will significantly effect the quality and quantity of sound you will achieve with your system. 13 TYPICAL SET-UP APPLICATION Stereo Cassette LEFT 9 0 2 RECORD LEVEL L R O13 124 RIGHT Volume 1 Value 2 Value 3 Value 4 Value 5 Value 6 Value 7 Value 8 Value Value Yes This Illustration was done A Value B Value by Phil Sanchez POWER PA U S E P L AY RECORD 2 1 3 4 -5 0 1 2 1 2 3 4 -5 0 1 2 TA P E S E L E C T NORMAL Cr O 2 M E TA L STOP REW FF January 27, 1997 No 14 GROUNDING AND HUMS Ground loops are one of the most common causes of hum and buzz in sound reinforcement systems and other audio products. A ground loop usually occurs if the separate pieces of equipment are plugged into different AC circuits. Also, if the audio wiring is placed too close to the power cords, hums or buzzes can bleed into the system. [. . . ]
