ROLLS CORPORATION SALT LAKE CITY, UTAH 7/99 OWNERS MANUAL INTRODUCTION The RD320 Digital Delay is used for speaker distance delay or speaker time alignment. The RD320 is housed in a single rack space chassis, and has two delay modes selected by a shorting jumper behind the front panel security cover. It provides a delay range of either 5 - 320 milliseconds, or 40 - 1280 microseconds. The delay is easily set from the front panel by setting the DIP switches, and the input and output levels are adjusted via front panel trim potentiometers. DESCRIPTION FRONT PANEL INPUT LEVEL +16 +10 0 -7 -13 PWR INPUT LEVEL OUTPUT LEVEL 5 10 20 40 80 160 OPERATION Cont. Selecting the Delay range Selecting the delay range is done by moving the shorting jumper on the front panel to the desired position. Either the long position (MS) for room time delay, or the short position (µS) for speaker driver alignment. Figuring the Long Time Delay Time delay in milliseconds (MS) is figured by adding the DIP switch ON (Switch Down) positions then add 5. Example, If the 5 and 80 switches are down, the delay time is 5 + 80 + 5 = 90 milliseconds of delay time. Figuring the Short Delay Time In the short position, figure the long time delay time, then divide by 128. For example, the minimum time delay is 5 milliseconds in the long position. In the short position it would be; 5 / 128 = 39 µS (or . 000039 sec). So that would be 1100 x . 000039 = . 043 feet, or multiplied by 12 inches = . 51 inches. D IG IT A L D ELA Y RD320 MS uS INPUT LEVEL LEDs: Indicate the amount of input signal level, in decibels. [. . . ] Set the output level to drive the power amp or signal processing that follows the delay. Remember to run the input level as high as possible without clipping to achieve the highest signal to noise ratio. That means the output level never cuts off the input level.
