Companion Speaker
DD-800 Digital Delay Module
Time Delay Calculation
The PA-810 is an AC or battery powered Companion System with a 96 Channel
Wireless Receiver for a wireless connection from a Titan Neo Sound System
with the TX-800 Wireless Transmitter installed.
The PA-810 can also be utilized as a self contained battery powered PA
system with the use of a hardwired handheld microphone (UM-66), or wireless
microphone (UT-96HH or UT-96BP).
With the addition of the DD-800 Digital Delay Module, the system becomes
PA-815.
The Digital Delay Module DD-800 is installed in the companion speaker and is
interfaced with DR-800 wireless receiver module. The output of the receiver is
passed through the delay module in route to the power amplifier. The purpose
of the delay module is to store the signal momentarily and then pass it through
to the amplifier input. The delay time can be varied from 20–500 milliseconds
thus synchronizing the sound output with the master unit on stage.
The true measurement of sound travel is 1125 feet per second. Thus sound
travels at the rate of 1.125 feet per millisecond (ms). So the general rule is to
round up to 1 foot per ms.
So to calculate the sound delay time from the main sound source to the distant
speaker is to pace the distance in feet. Then dial the foot count into the digital
delay module in milliseconds (ms). Example, if you were to pace off 150 feet,
you would dial the digital delay to 150 ms. Now this approximate setting could
be fine tuned by ear for a more exact setting.
Depress the power switch. The LCD screen will display the last saved delay time.
To change the delay time select the “SET” button. Using the UP/DOWN time
delay adjustment buttons, set the delay to the desired time in milliseconds.
Press the “SET” button to lock in your delay time.
