19. DELAY METER:
The three LEDs of the Delay meter perform multiple functions. When using the AUTO DELAY function of
the SA-4200™, the Delay meter indicates whether the current delay setting meets the criteria for correct
alignment. The
OK LED will light if the sound arrives at the TEST MIC (21) from the delayed loudspeaker
10 to 15 ms after the sound from the main reference system. The LONG LED lights if the delay time is
too long. The SHORT LED lights if the delay is set too brief. To allow easier reading of the LEDs in a dark
equipment rack, the LEDs that are unlit actually glow dimly to identify the pertinent “on” LED. In addition
to indicating the relative delay time, these LEDs are also used to indicate fault conditions in the test setup.
In these cases, the LED will blink.
Delay Measurement Fault Conditions
LONG LED blinking indicates that the required delay is greater than the 100 ms available.
OK LED blinking indicates that unit did not detect the test tone from both loudspeakers.
SHORT LED blinking indicates that the mic is not connected.
NOTE : This fault condition information is also printed on the rear of the amplifier.
20. DELAY SWITCHES (ACTIVE/BYPASS):
These switches activate or bypass each respective delay circuit in channels C and D. Each switch must be
ACTIVE for the AUTO DELAY to enter into the Test Mode (17) for each channel.
21. TEST MIC INPUT:
This input is used during delay adjustment to determine the required delay time. Almost any balanced
microphone will work for this application. Phantom power (15 volts) is supplied and will power most
condenser microphones. The test mic should be placed in the listening position nearest the auxiliary
loudspeaker system that is being delayed. If a directional mic is used, it should be positioned so that it picks
up signals from both the main and auxiliary loudspeaker systems.
22. TEST REFERENCE OUTPUT:
This output is an electronically balanced output that sends a test tone to the main “reference” sound
system. The output can be connected to mic- or line-level balanced inputs. Be sure to turn the channel
level and gain down before activating the delay test.
