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). The speed of sound at sea level is approximately 1100 feet/second. 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. INPUT LEVEL: Adjusts the amount of input signal. OUTPUT LEVEL: Adjusts the amount of output signal. DIP SWITCHES: Set the delay time MS: If the shorting jumper is in this position, the long delay time has been selected. µS: When the jumper is in this position, the short delay time has been selected. PWR: Indicates that the RD320 has power and the power switch is in the ON position.

Use these, along with the Ground terminal for a balanced output. IN: The "+" sign indicates the positive or non-inverting terminal, and the "-" indicates the negative or inverting terminal. Use these, along with the Ground terminal for a balanced input. OPERATION Setting the Input and Output levels Use the LED bargraph for setting the input level. With a typical sound level input, set the Input level as high as possible so the 0 dB LED is on approximately all the time, and the red +16 dB LED lights occasionally - only on the highest peaks. Set the output level to drive the power amp or signal processing that follows the delay. The input level range is from -infinity to unity gain. Remember to run the input level as high as possible without clipping to achieve the highest signal to noise ratio. The output level is from 0dB to 15dB gain. That means the output level never cuts off the input level.
