(A16) ANC-activated output setting (when the AN-001T is used and ANC operation is set to ACTIVE)

A N C A P P L I E S O U T 1

Set on which output channel the ANC function works.

Setting Range

OUT1 – 2, Max. 8 when T-001Ts are used (default: OUT1)

(A17) Monitor ON/OFF setting (when the AN-001T is used and ANC operation is set to ACTIVE)

M O N I T O R O U T – O F F

Set to ON or OFF the monitor function that permits the ambient noise input signal to be output.

Setting Range

ON, OFF (default)

ON: Outputs signals to be monitored.

OFF: Does not output signals to be monitored.

(A18) Monitor output channel selection

(when the AN-001T is used, the ANC operation is ACTIVE, and the Monitor function is ON)

M O N I T O R O U T – O U T 1

Select the output channel on which signals to be monitored are output.

Setting Range

OUT1 – 2, Max. 8 when T-001Ts are used (default: OUT1)

(A19) Lowest output level setting (when the AN-001T is used and ANC operation is set to ACTIVE)

M I N I M U M L E V E L – 6

Set the lower limit of the ANC-activated output level.

Setting Range –18, –15, –12, –9, –6 (default), –3 dB

Note: Settable level is 3 dB or more below the upper limit (highest output level).

(A20) Highest output level setting (when the AN-001T is used and ANC operation is set to ACTIVE)

M A X I M U M L E V E L

0

Set the upper limit of the ANC-activated output level.

Setting Range

–15, –12, –9, –6, –3, 0 (default) dB

Note: Settable level is 3 dB or more above the lower limit (lowest output level).

(A21) Sampling time setting (when the AN-001T is used and ANC operation is set to ACTIVE)

S A M P L E T I M E

2 0

Set the required time to measure ambient noise. The ambient noise level is determined by being averaged over the set measuring time. When the measuring time is long, the output level changes slowly with the ambient level. However, the change in output level is not susceptible to a sudden change in ambient noise level.

Setting Range

10, 15, 20 (default), 30, 60, 120,180, 300 sec
