This is a used and working TOAD-1103 one input by three output Digital Signal Delay adjustable from0 to 655 milliseconds. This is being sold because it was purchased for my system but the unit is deeper than my racks. I have used it some but replaced it with a smaller unit so that it fits my rack better.
Includespower cord and security cover.

PHYSICAL:Dimensions (W x H x D)ARCHITECT’S AND ENGINEER’S SPECIFICATIONSThe digital signal delay device shall be capable of delaying an audio inputsignal to each of three independently adjustable outputs. The minimumoutput time setting shall be 100 microseconds, including propagationdelay, and the time delay at each output shall be adjustable in 10-microsecond steps up to maximum delay of 655 milliseconds. The unitshall use 16-bit A-to-D conversion with a 100kHz sampling rate, and shallhave a maximum output-to-noise ratio floor of greater than 90dB. The inputcircuitry shall be electronically balanced and shall accept either balancedor unbalanced sources. The balanced input impedance shall be 10kohms. Each output circuit shall be electronically balanced and capable ofdriving a load of 600 ohms or greater. The unit shall accept optional inputand output transformers which shall be internally installed via standoffsand plug-in connectors. A7-segment LED input headroom display shallindicate 3dB below maximum output for the combination of input and inputlevel control settings. Frequency response shall be flat (±1dB) from 20Hzto 20kHz. The digital delay device shall include a digital display that canbe set to indicate the time delay of Outputs 1, 2 and 3. A front panelFine control shall allow the user to set the output delay for output 1, 2 or3 in summed high resolution (1 O-microsecond step) or low resolution(1 -millisecond step) modes. A Lock mode shall be provided whichdisables all front panel pushbuttons except the memory selection andFine keys. A back panel Protect switch shall disable all front panelpushbuttons, leaving only input and output level controls functional. Asecurity cover shall be provided to protect the front panel controls frombeing tampered with. The delay unit shall provide four preset memories forstorage of delay-time settings. The preset memories shall be accessiblevia front panel pushbuttons or remotely by means of contact closuresthrough a rear panel terminal strip. Up to 15 delay units shall beconfigurable, with a single master unit to initiate preset selection for allslave units. The unit shall contain a relay circuit which bypasses all internalelectronics in the event of power failure. lnput and output connectionsshall be made via rear panel terminal strip connectors. The unit shallmeasure 19.0\" wide x 1.7\" high x 14.0\" deep (483 x 44 x 357mm) with rackmount ears attached and shall occupy one standard EIA rack space. ACnoise suppression circuitry shall be built in to increase reliability.
