Panel Operations

■Calibration

Here you can detect the impedance value of the speaker connected to each channel, and apply the result to the alert settings

(Signal Chain threshold values).

• The impedance and output level cannot be detected when the output level is lowered by the attenuator.

●Calibrate by Pilot Tone

This performs the measurements using a pilot tone generated by the amp.

●Calibrate by Prog Source

This performs the measurements by outputting an audio source (program source) other than the pilot tone.

Parameter name Range Explanation

Frequency Type 5 Hz & 20 kHz,

10 Hz & 20 kHz

Speciﬁes the center frequency (5 Hz or 10 Hz) for the low-frequency

component of the pilot tone that is output to the speaker. The high-fre-

quency component is ﬁxed at 20 kHz.

With the exception of Start and Apply, the parameters listed below are

displayed and edited separately for the high-frequency component

(High) and low-frequency component (Low).

Enable ON/OFF Turns pilot tone output on/off.

Calibration Start Start Starts detection of level and impedance.

Detected Lvl — Indicates the detected level.

Detected Imp — Indicates the detected impedance value.

Apply Apply Based on the detected level and impedance value, settings will be

made for the Output Signal Chain screen (page 27) parameters Fre-

quency Type, Tone Level, Detect ImpMax (double the detected imped-

ance value), Detect ImpMin (half the detected impedance value), and

Detect TH (the detected level divided by √2).

Parameter name Range Explanation

Calibration Start Start Starts detection of impedance.

Detected Lvl — Indicates the detected impedance value.

Apply Apply Based on the detected impedance value, settings will be made for the

alert’s upper threshold value (double the detected impedance) and

lower threshold value (half the detected impedance).

Limiter Gain Reduction Voltage Limiter These settings specify how the limiter will be controlled by the output voltage. SIGNAL PATH Screen NOTE Page Page Slot Input Router Here you can specify the routing and gain from the slot input to each input channel. This is a 4-input 4-output mixer with the input channels and output channels arranged in a matrix. Input On/Off Here you can turn the input to the 4x4 Matrix Mixer on/off for each input channel. 8Band Input EQ Here you can specify a delay for the signal.
