INTRODUCTION

Congratulations and thank you for your purchase of the DOD SR 400 D room delay processor. With the SR 400 D room delay, dialing-in the unique sounds and characteristics of each venue is a breeze. The SR 400 D lets you enter in information such as Delay time, Room temperature and humidity and then it takes care of all of the calculations for optimizing the sound of the room. The SR 400 D provides you with single or dual input and output configurations, with two independent, programmable delays. The SR 400 D also comes equipped with XLR and Barrier strip Inputs and Outputs as standard features.

Safety Precautions

Do not open the unit. Do not attempt to service the unit yourself. Refer all servicing to qualified personnel. Opening the chassis for any reason will void the manufacturer's warranty. Do not get the unit wet. If liquid is spilled on the unit, shut it off immediately and take it to a dealer for service. Disconnect the equipment during storms to prevent damage.

SECTION 1 - GETTING STARTED

Supplying Power

The SR 400 D, like any piece of computer hardware, is sensitive to voltage drops, spikes and surges. Interference such as lightning or power "brownouts" can seriously, and in extreme cases, permanently damage the circuitry inside the unit. Here are a few tips that will help you get the best possible performance out of your SR 400 D while avoiding damage:

• Always make sure you have a "clean" power source for connecting to the SR 400 D. This means that the AC power line you connect to the SR

400 D should be as free from voltage fluctuations and RF interference as possible. In recording environments, "clean" power is also important in preventing AC hum or buzz from getting to tape.

• Use a good quality spike / surge suppressor (also called a power strip).

This is an inexpensive solution to all but the most severe AC line conditions. A good quality power strip can save you a lot of money in repair bills because they prevent large spikes and surges from reaching your equipment racks. Also in this category (but more expensive) are rack mount power supplies. Some of these (such as the DOD 828), have retractable light tubes and RF filtering.

• AC line conditioners offer the best protection from improper line voltages.

Line conditioners constantly monitor the AC line for excessively high or low voltages and instantaneously compensate to deliver a consistent voltage to the connected equipment.

• Always make sure that your audio lines are as far as possible from power cables. This will further prevent noise, hum, and stray magnetic fields from entering your signal path. If audio and power lines must run close to each other, try to avoid running them parallel to one another.

Front Panel Controls

SECTION 2 - PROGRAMMING THE SR 400 D

Selecting and Editing Delays

The SR 400 D is designed to be both easy to program and flexible. The structure of a SR 400 D is logical, and does not require a lot of time to master.

1) After you power up, Select which delay you wish to edit. Press either <Delay 1> or <Delay 2> buttons.

2) Now use the <Data Wheel> to change the Delay times. The Delays can be set to be read as the following with the minimum and maximum values accordingly:

Delay Milliseconds -

Delay Meters -

Delay Feet -

Min.= 00.0ms

Min.= 00.0m

Min.= 00.0 f

Max.= 2000.00ms

Max.= 697.651m

Max.= 2288.88f

Note: The Maximum Delay in Feet and Meters will vary depending on the Temperature and Humidity settings.

These Delay units can be changed in the utility menu.

Once the satisfactory delay unit has been entered, simply press the <Store> button to save changes.

Temperature

Since temperature plays such a big part of in acoustics of room delay, the SR 400 D lets you change enter in the temperature of the room, then the SR 400D will do the calculating to change the delay time. This change will cause the Audio signal to arrive at its Point of sound destination at the correct time.

Humidity

Humidity also plays a factor in the fluctuation of Room Delay times. The SR 400 D allows you to change the

Humidity percentage (this is performed in the utilities menu), so the sound reaches its Audio destination at the correct time.

Storing Delay Presets

Once all of the elements are in place and Delay settings are correct, simply press the store button and all changes will be saved.
