Chapter 2 Operation

This chapter describes how the BD500 is operated from the front panel using factory default configuration

values. Optional remote control and configuration are described in later chapters and appendices.

Installation

Rack Mount

Normally the BD500 will be mounted in a standard 19-inch rack using grommets to avoid damaging the front

panel overlay. The BD500 should be supported at the rear. The rack should be well ventilated and in a dry

and dust free environment so heat and moisture won't cause damage or degradation of performance.

Connect AC and Turn On Power Switch

Since the unit is electrically out of the audio path when in bypass mode, there is no reason to need access to

the rear panel power switch. The power-up mode is selected by the configuration and is the same regardless

of whether power is applied via the rear panel switch or via connecting the AC to an already switched-on unit.
The unit may be left powered on even if the rack's power is to be disconnected.

Immediately after the unit is switched on, the front panel will be fully illuminated. After several seconds,

the display will change to show

TST

. Just before the

TST

symbol is displayed the unit flashes the software

version number. The

TST

symbol is displayed for 15 seconds while the unit performs a test of it's audio pro-

cessing hardware. After 15 seconds the unit will read the front panel buttons (and basic remote control inputs).
If any buttons (except DUMP and SNEEZE) are pressed when the test cycle ends, the unit will perform a spe-
cial start-up function (see Appendix F.) If no buttons are pressed, the unit will (by factory default) complete

it's start-up. The display will show

---

and the BYPASS button should be illuminated. This combination of

LEDs indicates that the unit is powered on and in bypass mode.

Level Meters

There are two 10-segment LED bar graphs to display input level information. These graphs act as meters

and may be used to align the equipment so adequate audio levels are presented to the BD500. The meters
indicate the levels at the digital signal processor and are calibrated in decibels. The top LED is red. The next

two are yellow, and the bottom seven are green. The red LED is lit if the level reaches clipping. The remain-
ing LEDs indicate approximately -3
