SECTION 1 - GETTING STARTED

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.

The front panel of the SR 400 D is laid out in a simple and straight forward way to

make programming as easy as possible. Functions of each section are:

1) BYPASS - This button puts the SR 400 D into Bypass mode. This button also

scrolls the display screen to the left when the SR 400 is in utility mode

2) MODE - This button lets you select the INPUT and OUTPUT modes of the SR

400 D. The selections are: 1 IN and 2 Out or 2 IN and 2 Out. This button also scrolls
