The NUX NDD-7 Tape Echo is an echo and delay processor with 7 different types of simulation to recreate the sound of vintage echo units. In addition to classic tape echo simulation, the NDD-7 has a separate spring reverb effect, sound-on-sound (SOS) for operation as a 40 second looper, and up to 1600ms of delay. Up to 1600ms stereo delay time by Tap Temp 7 Repro-Tape Heads combinations and Reverb only Core-Image technology brings natural Tape Echo with parallel spring reverb sound back Holding ON footswitch for self-feedback Sub-division time signature with Tap Tempo foot switch 40 seconds stereo phrase loop with OLED status display Optional delay time display (MS / BPM) MIDI In/Out Holding ON footswitch for self-feedbackSpecifications Sampling rate：48kHz A/D Converter：32Bit Signal Processing：32Bit Frequency Response：20Hz~20kHz - ±1dB Input Impedance：5MΩ Maximum input level：1.5Vrms Output Impedance：100Ω Maximum output level：1.5Vrms System Latency：1ms Dynamic Range：103dBu/105dBu(A-Weighting) THD+N Ratio：0.0038% @ input 1Vrms_1kHz ；0.01% @ input 1.5Vrms_1kHz Power：9V DC(Negative tip, Optional ACD-006A adapter) Current Draw：approximately 100mA，
