– CAM160 / CAM80
Ducking will take place within 300 mS of detecting that an
input signal has crossed the ducking threshold. This delay
also applies to the manual activation of the Priority circuit
by the use of external contact closures.
When the signal that initiated the ducking stops, or manual
activation has ceased, there will be a one second timeout
period to make sure it is completely over. When it is over,
the other inputs will ramp up to their original volume over
the next 0.5 seconds.
13. Priority Functions
Priority means that you can manually duck the other
channels using an external switch, and play only input 1 or
input 2.
Priority functions can be initiated by a user-supplied,
normally open, dry contact closure switch (or switches)
connected to the terminal strip (GND, Priority 1, Priority 2).
Connecting one leg of the switch to the GND
screw and the other side to either PRI 1 or
PRI 2 prepares the circuit. Closing the switch
actuates the specific priority, allowing input 1
or 2 to play
14. Chime Function
Chime functions can also be initiated by means of user-
supplied, normally open, dry contact closure switch (or
switches) connected to the terminal strip (COM, Chime 1,
Chime 2).
Connecting one leg of the switch to the COM
screw and the other side to Chime 1 or Chime
2 prepares the circuit. Closing the switch
actuates the Chime.
INPUTS 3, 4, 5, 6
Inputs 3, 4, 5 and 6 have identical connections and
controls. (Input 3 is shown here.)
INPUT CONNECTORS
Inputs 3-6 each have two different styles of input
connections. Choose one which suits your system the best:
15. Phoenix (Euroblock) connector.
This
three-pin connector accepts the positive, negative
and ground terminals of a balanced audio line. It
accepts push-in connectors for easy installation.
16. Terminal strip.
This three-terminal connector
accepts the positive, negative and ground
terminals of a balanced audio line. Secure the
connections with the screws.
All inputs are designed to accept balanced or unbalanced
microphone-level signals, or may be configured to accept
line-level signals by means of DIP-switches 1 and 2
(explained below).
17. GAIN pot and LED
This screwdriver-adjustable rotary potentiometer acts as a
trim control, and a red indicator LED displays the nominal
input level. With normal source material playing, adjust
the pot until the LED lights only occaisionally during the
loudest moments of your program. (The LED will light 3 dB
before clipping.)
18. DIP switches
Each input 3-6 has a five-pole DIP-switch
from which the inputs (both types) can be
configured. (These are identical to the first
five switches of inputs 1 and 2 described
on page 5.)
