1. WARNING TO PREVENT ELECTRICAL SHOCK OR FIRE HAZARD bo NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE BEFORE USING THIS APPLIANCE READ THE OPERATING GUIDE FOR FURTHER WARNINGS DPM SX MANUAL UPDATE REVISION TO UPDATE CHAPTER 3 Chapter 3 Using the SX as a Stand Alone Sampler The DPM SX can be used as a high performance front end sampler for any PCM sample player sample editor or sample storage unit that supports the MIDI Sample Dump Standard or is capable of transmitting and receiving MID System Exclusive messages It has been designed with a full complement of controls available from the front panel that allows operation in a wide variety of applications This chapter presents the use of the DPM SX as a stand alone front end sampler that can be us ed in the most general applications To use the DPM SX as a stand alone sampler e Connect your sound source into one of the two input jacks on the front panel of the DPM SX If you are using a microphone connect it to the XLR jack If you are using a CD player mixer output or other line level signal connect it to the 1 4 phone jack Select the desired sample rate depending on the desired sound fidelity or fre quency response by depressing the SAMPLE RATE button on the front panel Using this button the sample rate can be set to either 24 kHz or 48 kHz providing bandwidths of either 10 kHz or 20 kHz respectively2. While playing the instrument or sound that is to be sampled adjust the input level control until the clip threshold LED flashes red only for an instant on the peaks of the signal As you become more familiar with the DPM Sx you will determine what the optimal signal level is for your own specific needs If the sampling is to be initiated by the input signal depress the ARM button The LED indicator above the ARM button will begin to flash indicating that the sampler is armed and waiting on the input signal to trigger the sampling process The default trigger level is 30 dB down from the clip level If the sample is to be manually initiated from the front panel it is not necessary to arm the sampler It is only necessary to depress the START STOP but ton at the beginning of the sample and depress it a second time at the end of the sample If the sample memory is filled before the START STOP button is depressed the second time the sampling process will automatically stop Note The sample length in seconds will be determined by the sample rate that has been selected and the total amount of memory that has been loaded into the unit For example At a sample rate of 48 kHz with 1 Megabyte of memory the total sample time will be approximately 11 seconds At this point the sample resides in the DPM SX sample memory It can now be transferred to the sample player sample storage unit or sam
