Audio level reset — single input

Reset the audio level for an input to 0 dB as follows:

 

 

The switcher must be in normal (manual) mode.

1.

Press and release an input button to select an input.

2.

Press and hold the Audio Conf/Save button until the Conf/Save LED begins

 

to blink, then release the Conf/Save button.

3.

Press and release the and buttons. The and LEDs light and the

 

Input LEDs go off.

4.

Press and hold the Audio Conf/Save button until the Conf/Save LED goes

 

off. The and LEDs go off, and the selected Input LED lights.

Audio level reset — all inputs

Reset the audio level to 0 dB for all inputs as follows:

1.

Press and hold the Audio Conf/Save button for approximately 10 seconds

 

until all Input LEDs light for approximately 1 second and then turn off.

 

Release the Conf/Save button.

2.

Press and hold the Audio Conf/Save button again until the Conf/Save LED

 

turns off to save the reset level in memory and exit the audio display and

 

adjustment mode.

Memory

Audio and switch mode settings are saved in nonvolatile memory. When the switcher is powered off, the settings are retained. When the switcher is powered on, the saved memory settings are active. The selected input is not a saved value; when the switcher is powered on it defaults to input 1.

If the switcher is powered off in autoswitch mode, it automatically switches to the highest-numbered input with video sync pulses present when it is powered back on. If no input has video present, all input select LEDs are off.

Optimizing the Audio (SW2, SW4, and SW6 RGBHV A only)

Each individual input audio level can be adjusted within a range of –18 dB to

+24 dB, so there are no noticeable volume differences between sources and for the best headroom and signal-to-noise ratio. Adjust the audio gain and attenuation as follows:

1.

Connect audio sources to all desired inputs and connect the audio outputs to

 

output devices such as audio players. See Inputs and Output, in chapter 2,

 

Installation.

2.

Power on the audio sources, the switcher, and the audio players.

3.

Switch among the inputs (see Switching inputs, in this chapter), listening to the

 

audio with a critical ear or measuring the output audio level with test

 

equipment, such as a VU meter.

4.

As necessary, adjust the audio level of each input (see Adjusting audio gain and

 

attenuation (audio switchers), in this chapter) so that the approximate output

 

level is the same for all selected inputs.
