The Digital Sound Sampler's ( hereafter referred to as the DSS ) audio output consists of a RCA female connector as the primary output and a two pin header, located underneath the RCA connector, as the secondary output. Both connectors provide the same signal. These outputs are capable of directly driving an 8 ohm speaker or they can be connected to an external amplifier through a suitable high level input. ( Usual labels for such inputs on amplifiers are "AUX" or "LINE". ) Needless to say, samples will sound better when reproduced through quality equipment. Be sure to use a shielded cable to connect the DSS to all external amplifiers. The jumper located to the upper right of the RCA plug controls a small high Pass filter ( this is just a quick and dirty RC filter so don't expect miracles ). "On" means the filter is filtering high frequencies out of the audio output signal.
Inputting an audio signal into the DSS is accomplished using the 3.5mm female mini-plug located at the middle-top of the DSS. To the rear of the 3.5 plug is a small potentiometer controlling input gain. Just below the 3.5 plug is a three pin header. This user selectable option controls the input sensitivity BY selecting the "LO" setting ( shorting pins 1 and 2 ) the DSS accepts input levels between 200mv to 4 volts ( peak to peak ).This setting is optimum for inputting from tape recorders, synthesizer or similar 'line' level outputs. By selecting the "HI'- setting ( shorting pins 2 and 3 ) the DSS accepts input levels between 1Omv to 200mv. This setting is optimum for connecting a microphone to the DSS. Input resistance is aprox. 100k ohms.
