TOA ENGINEERED SOUND PRODUCT
DIGITAL SOUND DELAY
D-1103
DESCRIPTION
The TOA D-1103 is a One-by-Three Digital Delay, designed
for a wide variety of applications such as theaters, concert
halls, houses of worship, auditoriums, large meeting rooms,
arenas and stadiums.
Delay times range from 10 microseconds (1/8 inch) to 655
plastic security cover is included to restrict access to all
front panel controls.
An automatic bypass function permits complete signal
bypass of the unit in the event of an AC power loss.
Terminal strip connections are used for electronically
balanced inputs and outputs. High quality, low distortion
milliseconds (approx. 750feet). Ten-microsecond incre- input and output transformers with 30Hz 20kHz response
ments are maintained throughout the entire delay range, are optional and installation requires no soldering.

component alignment. rackspace.
The use of 16-bit, 100kHz analog-to-digital conversion
allows the D-1103 to achieve superb audio quality, with
dynamic range better than -90dB and THD below 0.03%.
Delay information may be stored in four non-volatile preset
memories, permitting instant set-ups. The preset memories
can be accessed with front panel switches or remotely via
contact closures. This permits simultaneous activation of
several interconnected units, either externally or by means
of a master D-1103 unit. A removable screw-terminal link
sets the status of the D-1103 as a master or slave unit.
A rear panel protect switch disables all front panel functions
except level controls, to prevent tampering. A smoked
