[. . . ] 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. Opening the chassis for any reason will void the manufacturer's warranty. 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. 2 SR 400D manual 6/8/99 10:54 AM Page 3 Signal Processing Signal Processing 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. Set this level until the CLIP LED begins to light and back off the knob slightly. When the INPUT knob is set properly, the CLIP LED should flicker dimly on only the loudest passages. 11) INPUT KNOB CHANNEL 2 - Use this knob to control the input level of Channel 2. Rear Panel Connections 1 2 3 4 5 6 7 The SR 400 D's rear panel is even simpler than the front, and that means faster hookup times for you. To select either of the two modes, press the <Mode> button and use the <Data Wheel> to change the configuration mode. To exit the Mode function, press the <Mode> button again. Bypass Selection By pressing the <Bypass> button on the front panel of the SR 400 D, this places the unit in Bypass mode. The unit will continue to pass signal. SECTION 3- UTILITY MENU FUNCTIONS The Utility menu within the SR 400 D offers the User countless functions to help in programming and using the unit to its fullest potential. The following pages give performance function notes for the all of the sub-menus of the SR 400 D. Key Lock Out This unique function of the SR 400 D lets you lock-in your Delay settings and keep them that way. To set the Key Lock, first press the <Utility> button and use the <Mode> button to scroll to the right. Once you are at the Key lock function, turn the <Data Wheel> clockwise until the word: Locked appears in the screen. Now a lock icon will appear in the display, indicating that the Delays are locked in place. To unlock, press and hold the <Delay 2> button for approximately 5 seconds. Temperature Unit Selection The SR 400 D can display temperature in either Fahrenheit or Celsius Degrees. [. . . ] To change the percentage of humidity so the SR 400 D will calculate the correct delay, press the <Utility> button and use either the <Bypass> or <Mode> buttons to scroll to the Humidity setting. Note: This utility function can only be used when the Delay Unit is being measured in Feet or Meters. 6 SR 400D manual 6/8/99 10:54 AM Page 7 Signal Processing Signal Processing Temperature The temperature of a venue also plays a crucial role in affecting the Room delay. Once the correct temperature is entered, the SR 400 D will re-calculate the Room delay so the correct delay is used. The procedure for changing the Temperature of the SR 400 is as follows: From performance mode, press the <Utility> button and use the <Bypass> and <Mode> button to scroll to the Temperature setting.
