From Diamond:

Blending analog companding, anti-aliasing|reconstruction filters with a bucket brigade style delay line, we have immaculately captured the ethereal essence of the original big-box Memory Lane using Diamond’s innovative digital Bucket Brigade Delay technology (dBBD). Basically what we’re saying is, you get all the goodness of the original Memory Lane in a smaller footprint, over double the delay time, extended frequency response, higher SNR, and at a fraction of the current draw.  

This innovative progression of the Memory Lane is defined by 3 distinct delay lines to offer modern or vintage sounds.  

Input Impedance: > 1MΩ

Output Impedance: < 10KΩ

Switching: Buffered Bypass

Power Requirement: 9 VDC , negative tip, 2.1 mm barrel jack. 

Current Draw @ 9 VDC : 45mA

Dimensions: 122 x 66.98 x 39.64 mm (4.8 x 2.64 x 1.58")

Weight: 300 g
