Roland SPD::ONE Series Percussion Pad Roland SPD-1W SPD ONE WAV PAD Digital Percussion Purchased new around January of this year. I opened it once, but I didn't end up using it, so I've kept it in storage, unused. It's in like-new condition, and all the accessories are included. The AC adapter is normally sold separately, but I'll include it as a bonus. It's not a Roland AC adapter, but it works without any problems! ■ Main Specifications ● Number of Waves that can be Recorded: 12 (excluding layers/click waves) ● Memory: 4GB (Stereo approx. 360 minutes / Mono approx. 720 minutes) ● Data Format: WAV (44.1kHz, 16-bit, Stereo/Mono) ● Controls: WAVE knob, [PHONES] knob, [MIX] knob, [MASTER] knob, [ALL SOUND OFF] button, [THRES] knob, [SENS] knob, [POWER] switch ● Indicator: TRIG indicator ● Connectors: MASTER OUT(STEREO) jack (standard type), PHONES jack (stereo standard type), USB port (USB Micro-B type), DC IN jack ● USB: MIDI, file transfer (mass storage) ● Power Supply: Rechargeable nickel-metal hydride batteries (AA) x 4, Alkaline batteries (AA) x 4, AC adapter (DC9V) ● Current Draw: 300 mA (DC IN) ● Battery Life (Continuous Use): ＜Rechargeable nickel-metal hydride batteries＞ Normal use = approx. 7 hours, Maximum load use = approx. 4 hours ＜Alkaline batteries＞ Normal use = approx. 6 hours, Maximum load use = approx. 3 hours * Varies depending on battery specifications, capacity, and usage conditions. ● Dimensions (excluding attachment): 140 (W) x 160 (D) x 56 (H) mm ● Weight (including batteries, excluding attachment): 900g ● Accessories: Instruction manual, "Safety Precautions" leaflet, Attachment, Attachment mounting screws x 2, Percussion holder mounting screws set (bolt x 1, nut x 1, washer x 2), Alkaline batteries (AA) x 4, Warranty card, Roland User Registration Card
