RECORD TRIGGER THRESHOLD The record trigger threshold is the input amplitude level that is required to start the process of recording a sound. To set the record trigger threshold level, press the SAMPLE RATE button again. The display will show: RECORD AT -18 D B Use the number pad or the arrows to set the threshold level to any value between 0 and -45db. The number displayed corresponds approximately with the level you see on the LED meter. When the Prommer is in a "ready to record" condition, the recording will start when the input signal level exceeds the record trigger threshold. The Prommer uses a pre-record buffer so that the leading edge of the audio cycle that triggers it will not be lost. This allows recording data starting with the first zero level crossing before the trigger point to eliminate any clicks or thumps that may be caused by starting a sound at the wrong phase of a cycle. If you want to be able to record immediately without waiting for the input signal to trigger, just set the threshold level to its minimum value of -45. Recording will then start as soon as record mode is entered (see below). Pressing the SAMPLE RATE button again will take you back to the SAMPLE RATE display. RECORDING A S O U N D To record a sound, press and hold the RECORD button. If the current block length is greater than 15 bytes and the block is not protected, the display will read: PRESS PLAY. . . Still holding the RECORD button, now press the PLAY button. The display will now read: RECORDING. . . Now the Prommer will wait for the input signal to reach the record trigger threshold. (You may now release both buttons.) When the input signal becomes loud enough to cross the threshold, the Prommer will start recording into the current block and the display will read: RECORDING. . . N O W Recording will continue until the current block is full. After you record a sound you can play it back by pressing PLAY. You can rerecord a sound if you want to - just press RECORD and PLAY again.
