This chapter provides a basic overview of the 6000 by describing the input and output connections, power con-
nection, operating controls, front panel LED indicators, and the remote indicator and control interface. Use this
information to acquaint yourself with the product.
Chapter 4 (Installation)
gives details on installing the 6000 in
your system and
Chapter 5 (Operation)
gets into specific applications and uses of the 6000 in detail.

Summary Product Description
• The BYPASS button places the 6000 in either BYPASS or OPERATE modes. In BYPASS mode the incoming sig-
nals are directly routed (via relays) to the 6000's outputs, thereby bypassing any internal circuitry. In addition, the
digital I/O is relay bypassed. In BYPASS mode, the front panel and remote controls have no effect on the opera-
tion of the 6000. In OPERATE mode, the incoming signals are processed through the 6000’s analog and digital
circuitry, and all front panel and remote controls are fully functional.
• The PREVIOUS button displays the previous menu of the 6000’s menu setup hierarchy in the LCD display.
• The NEXT button displays the next menu of the 6000’s menu setup hierarchy in the LCD display.
• The HOME button returns the 6000’s LCD DISPLAY to the default operating screen which shows the following
information:
1. The top line of the LCD DISPLAY shows the input or output levels for audio channels 1 and 2. Each is
labeled with a numeral 1 or 2 respectively to the left. A bar graph meter will display to the right of each
numeral. Each bar graph increment represents 1 dB of signal for a peak level metering range of -40 to 0
dBfs.
2. The bottom line of the LCD DISPLAY shows the current operating status of the 6000. For example, 6000
BYPASSED, DELAY REMOVED, ADDING DELAY TIME, REDUCING DELAY TIME, WAITING FOR
RELEASE, MUTED, or MAXIMUM DELAY.
• The ADJUST knob scrolls through the available parameters to each setup menu item.
• The LCD DISPLAY shows the current menu item in the setup menu hierarchy as well as its current setting. It also
shows the ‘home’ screen as described under HOME (see above).
• The A1 through A4 LEDs show the state of the four internal relays used for delay automation. The LEDs will be off
when the relays are unenergized, green when energized and red when cued to be energized. Further description
of this feature is provided in
chapter 5
.
• The DELAY numerical readout shows the length of delay time built up by the 6000 in tenth of a second incre-
ments.
• The EXIT DELAY button initiates the gradual reduction of delay time. Once this button is pressed, assuming no
other control button is subsequently pressed, the 6000 will proceed to incrementally reduce delay time until a zero
delay is achieved.
• The START DELAY button initiates the gradual increase of delay time. Once this button is pressed, assuming no
other control button is subsequently pressed, the 6000 will proceed to incrementally increase delay time until a
user-determined preset second delay is achieved up to a possible full 40 seconds.
• Pressing the COUGH button pauses the incoming signal while allowing the output signal to play (uninterrupted)
from the 6000’s memory. The 6000 will continue to play from memory for so long as the button is pressed. When
the COUGH button is released, the 6000 resumes recording into memory and "splices out" the silence created
while the button was pressed. The 6000 then begins to rebuild the delay time used while the COUGH button was
pressed. The listener will be aware of a program interruption if and only if the button is held for a time exceeding
the time in memory, in which case the input is muted.
• Pressing the DUMP button erases a user-determined portion of the 6000’s delay memory. The 6000 will then pro-
ceed to splice back together everything except the erased audio. Next, if no other control button is subsequently
pressed, the 6000 will proceed to incrementally increase delay time until the user-determined second delay is
again achieved. See
chapter 5
for further explanation of the DUMP function and its delay length settings.
