Monitor Delay (Parameter No. U15)
When the monitor speakers are located a significant
distance from the main house speakers the resulting
delay between the two sources can severely reduce the
intelligibility of the sound. In such situations the
PM5000’s internal digital delay system can be used to
delay the monitor output so that it becomes “time
aligned” with the main house sound for maximum
clarity.

Press [ENTER] after selecting the above display and
one of the monitor delay parameters will appear on
the parameter display: DELAY (the master delay
switch), UNIT (the delay units to be used:
milliseconds, feet, or meters), or TIME (the actual
delay value). Normally you will start by turning the
DELAY parameter ON, and then set the delay time
as required. Select a parameter and press the
[ENTER] key.
Master switch:
Turns the monitor delay ON or OFF. When ON the
MONITOR DELAY LED will light.
Delay units:
Determines whether the delay time will be set in
milliseconds (msec), meters (meter), or feet.
Delay value:
The actual delay value based on the selected UNIT
type. The maximum available delay is 1,800
milliseconds.

Use the [INC] and [DEC] keys to set the selected
parameter as required.
300/1000 (sec) x 1127.26 (feet/sec) = 338.178 (feet)
300/1000 (sec) x 343.59 (meter/sec) = 103.077 (meter)

D E L A Y : O F F
U N I T : m s e c
T I M E : 3 0 0 m s
NOTE
If the unit type is changed after the delay value is set, the delay
value will be recalculated and displayed according to the unit
type selected (sound travels at 343.59 meters per second, or
1,127.26 feet per second under normal conditions). This is just an
approximation, however, and for maximum accuracy it is
advisable to set the delay value after the unit type has been
specified.
