ROLLS CORPORATION SALT LAKE CITY, UTAH 6/03 OWNERS MANUAL INTRODUCTION The RD1024 Digital Delay is used for speaker distance delay. With the extra memory it may even be used as part of a broadcast profanity delay. The RD1024 is housed in a single rack space chassis. PLEASE NOTE: THIS MANUAL ASSUMES THE USER HAS A WORKING KNOWLEDGE OF BASIC AUDIO CONNECTION AND OPERATION PRINCIPLES. DESCRIPTION FRONT PANEL OPERATION Cont. Selecting the Delay range The number of switches in the up position determines the delay time + 4 mS. Each switch to the left doubles the delay time and you add the number of switches up delay times to calculate the total delay then add 4 mS. The Switch positions are 4 8 16 32 64 128 256 512 mS Figuring the Time Delay Time delay in milliseconds (mS) is figured by adding the DIP switch OFF (Switch Up) positions then add 4. Example, If the 4 and 64 switches are up and the rest down then the delay time is 4 + 64 + 4 = 72 milliseconds of delay time. SCHEMATIC pwr INPUT LEVEL LEDs: Indicate the amount of input signal level, in decibels. INPUT LEVEL: Adjusts the amount of input signal. OUTPUT LEVEL: Adjusts the amount of output signal. DIP SWITCHES: Set the delay time JUMPER: for setting the maximum delay X 4 if extra RAM has been installed PWR: Indicates that the RD1024 has power and the power switch is in the ON position.
