[. . . ] User Guide Unpacking and Inspection After unpacking the unit, save all packing materials in case you ever need to re-ship. Thoroughly inspect the unit and packing materials for signs of damage. Report any shipment damage to the carrier at once; report equipment malfunction to your dealer. Notice This equipment generates and uses radio frequency energy and if not installed and used properly, that is, in strict accordance with the manufacturer's instructions, may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class B computing device in accordance with the specifications in Subpart J of Part 15 of FCC Rules, which are designated to provide reasonable protection against such interference in a residential installation. [. . . ] This can cause signal overload as echoes continually accumulate. To select a new echo rate at any time, just TAP twice. RESET/BYPASS allows you to mute the current rhythm while tapping in a new one. 3. Press FUNCTION again to hear your original echo rate change to eighth-note triplets. Press FUNCTION again to hear your original echo rate in sixteenth-notes. Note that you can set any of these rhythmic variations before you tap in a tempo -- allowing you, for example, to tap in quarternotes and get a sixteenth-note echo rate. Vary the rhythm FUNCTION allows you to select among four echo rates on the fly: the rhythm you TAP in, and three variations on your original rhythm. To hear how this works: Change the echo rate To change the echo rate, simply TAP two beats -- JamMan will adjust the echo rate to whatever rhythm you tap -- so the results will always be musical. Now, anything played through JamMan will have a one-beat echo repeat at whatever tempo you tapped. Play audio through JamMan, and TAP in two quarter-notes in time with your audio source. -- Note that the uppermost display LED is lit to indicate division of the original echo rate by 2. 9 More about ECHO mode Remember that it takes only two TAPs to set an echo rate . . . If TAP is only pressed once, JamMan will set the longest echo rate possible (8 seconds, or 32 seconds, depending on the memory capacity of your unit. ) The TEMPO LED, will light solid on the first TAP, then start blinking at the selected echo rate after the second TAP. This LED continues to blink at the tapped in echo rate, no matter what rhythmic variation is chosen. Pressing FUNCTION gives you four rhythmic variations of any rhythm you TAP . . . Tapped-in Rhythm Rhythmic Variations FUNCTION Setting (No LEDs Lit) MUTE / LAYER / REPLACE / 10 Sample Mode SAMPLE mode allows you to capture a single sample of as long as 8 seconds (32 seconds with memory upgrade). Once a sample is recorded, you can set it to play forward or backward. -- You can even change direction as many times as you like during playback. You can trigger play manually (or via footswitch), or set it to play in response to one of fifteen levels of audio threshold. Set Mode knob to SAMPLE. MIDI 3 4 6 8 12 16 24 ECHO PUNCH IN LOOP MIDI 3 4 6 8 12 16 24 PHRASED LOOP SAMPLE With JamMan on, and an audio source connected, 1. Set the front panel MIX control halfway between DRY and WET. 11 Basic Sampling FUNCTION Toggles "+" and "-", selecting whether the recorded sample is to play forward or backward. TAP If no audio trigger is specified via SELECT, first push starts recording; second push stops recording. If an audio trigger has started recording, first push will stop recording. If an audio trigger is set to 2-16, pressing TAP overrides the audio trigger to start recording. SELECT Selects audio threshold which triggers start of sample record or play. ( 1 = manual trigger via TAP, 2-16 correspond to increased sensitivity -- lower audio levels required for trigger. ) 12 LEDs are Inactive in this mode. RESET/BYPASS Resets the unit to sample record ready. Does not affect audio threshold or +/- settings. RESET/BYPASS MUTE/ LAYER/ REPLACE/ FUNCTION SELECT TEMPO TAP DISPLAY + = Sample selected to play forward; flashing = ready to record = Sample selected to play backwards 1-16 = Audio trigger threshold · = Indicates audio sample is stored Single segment chase pattern indicates sample record; dual segment chase patterns indicate forward and backward sample play. Manually-triggered samples 1. Set SELECT to "1" to allow TAP to trigger sample record start and stop. The display will show a single-segment chase pattern to indicate JamMan is recording. [. . . ] · Watch for bent pins on ICs. ICs must be inserted with the beveled corner facing the rear of the unit. Label MCM54400AZ HM514400AZP D424400V MB814400 M5M44400L MT4C4001JZ Installing four 1M x 4 bit ZIP ICs increases JamMan memory from 8 to 32 seconds. Before performing the memory upgrade procedure, disconnect JamMan from its power supply. 22 1. Remove the six (6) hex nuts on the rear panel connectors by turning them counterclockwise. Note for reassembly that the screws at the center top, center bottom, and on the rear, are shorter than the others. Pull out the rackmount extensions on each side of the unit, and slide the cover off of the unit. 4. [. . . ]
