Change
[m][°C] ↔ [feet][°F]
• Enable the test signal at the reference
speaker A. Switch off all other
speakers.
• The delay time of the acoustic signal
with reference to the electrical input
signal is displayed in milliseconds. The
distance result in meter/feet is displayed
for easy verification of the test results.
The readings are based on 330 m/s
sound speed at 0°C / 32°F.
• Set the actual environment temperature,
so the distance is displayed correctly.
Store reference
• Select STORE to memorize this test
result as reference record for further
delay time measurements.
• The stored reference delay time is
shown in the delay time memory field.
Measure Propagation Time at Speaker B
• Enable the test signal at the speaker B.
Switch off all other speakers.
• The acoustical delay time of speaker
B with reference to the electrical input
signal is displayed as big test result.
Automatic Time Difference Calculation
• The delay time difference is automatically
calculated and shown in the upper small
STO-ACT (stored - actual) field.
The automatic difference calculation
simplifies the verification of delay line
arrangements, e.g. used in larger halls
or auditoriums.
