What was old is new again. Immerse yourself in the sound of classic 100 percent analog BBD delay tones under the full control of an advanced smart CPU. Lush delays with natural depth and endless tonal colors let you dial up delays for any situation and store them in 1 of 4 onboard memory slots. Choose from classic, vintage, non-linear, or nine other modes for the base of your delay, then tweak the modulation, delay time, intensity, and more. There's even a multi-head mode to simulate the wow and flutter of classic tape delays! And you'll always be on time with a versatile tap tempo that operates at half, quarter, and eighth note divisions and can be set to triplet and dotted values. Take it even further with MIDI I/O capability that provides remote access to 127 user memories, MIDI sync, and more. Integrated selectable carryover means you'll never lose your tails when you kick off or switch delays......unless you want to. You can even bring your external footswitches or control pedals to the party thanks to the DM-101's versatile I/O.Boss DM-101 Features:The ultimate analog delay pedal realized with advanced BOSS technologyFully analog BBD audio circuitry shaped by precision digital CPU controlWarm, saturated, and highly musical toneTwelve modes deliver a wide range of mono and stereo delay textures, created using up to eight internal BBDsStereo output with flexible signal routing optionsAdjustable modulation rate and depth with dedicated knobsVariation knob for controlling multiple parameters that are unique to each modeSelectable carryover for maintaining delay trails when the effect is bypassedMIDI I/O on mini TRS connectorsTap tempo function and tap division switch for creating rhythmic delaysFour onboard memories plus the current panel settings127 user memories accessible via MIDI program changeExpandable control via external footswitches, an expression pedal, or MIDIBoss DM-101 Specifications:Memory: 127 + ManualNominal Input Level: INPUT: -10 dBuInput Impedance: INPUT: 1 M ohmNominal Output Level: OUTPUT A/MONO, OUTPUT B: -10 dBuOutput Impedance: OUTPUT A/MONO, OUTPUT B: 1 k ohmRecommended Load Impedance: OUTPUT A/MONO, OUTPUT B: 10 k ohms or greaterDelay ModeCLASSICVINTAGEMODERNMULTI-HEADNON-LINEARAMBIENCEREFLECT [STEREO]DOUBLING+DELAY [STEREO]WIDE [STEREO]DUAL MOD [STEREO]PAN [STEREO]PATTERN [STEREO]Bypass: Buffered bypassControlsON/OFF switchMEMORY switchTAP switchMOD RATE knobMOD DEPTH knobVARIATION knobMODE knobDELAY TIME knobINTENSITY knobDELAY VOLUME knobMEMORY buttonTAP DIVISION buttonConnectorsINPUT jack, OUTPUT A/MONO jack, OUTPUT B jack: 1/4-inch phone typeCTL 1, 2/EXP jack: 1/4-inch TRS phone typeMIDI (IN, OUT) jacks: Stereo miniature phone typeDC IN jackUSB port: USB micro B-type (program update only)Power Supply: AC adaptorCurrent Draw: 260 mAAccessoriesAC adaptorOwner’s ManualLeaflet (“USING THE UNIT SAFELY“, “IMPORTANT NOTES“ and “Information“)Rubber foot x 4Options (sold separately)Footswitch: FS-5UDual footswitch: FS-6, FS-7Expression pedal: FV-500H, FV-500L, EV-30, Roland EV-5MIDI/TRS connecting cable: BMIDI-5-35, BMIDI-1-35, BMIDI-2-35, BCC-1-3535, BCC-2-3535SIZE AND WEIGHTWidth:192 mm, 7-9/16 inchesDepth: 133 mm, 5-15/64 inchesHeight52 mm2-3/64 inchesHeight (including rubber foot)53 mm2-3/32 inchesWeight830 g1 lb 14 oz Boss DM-101 Delay Machine Stereo Analog Delay Effects Pedal.
