Kramer Electronics Operating the VA-8xl, Adjusting the Gain/Attenuation of the Channels

5 Operating the VA-8xl

When switching on the VA-8xl(after a previous session), the VA-8xlbriefly scans each channel (stored in the non-volatile memory), showing the settings in the LED displays. After that, the VA-8xlgoes to channel 1, and shows its gain/attenuation level in dB.

During regular work, the VA-8xlshows the status of the last channel you observed and/or changed.

To observe the status of a channel:

•Press a CHANNEL SELECTOR button.

That CHANNEL SELECTOR button illuminates for about 20 seconds and the decibel values of the selected channel appear in the dimmed LED displays

When the LEDs are dimmed, you cannot change the gain or attenuation - the values are for observation only

You can control the amplifier gain of the left and right channels via the front panel buttons, or remotely via RS-232 or RS-485. You can increase or decrease the gain in increments of 0.5dB from -95dB up to +31dB.

You can control the amplifier gain of the left and/or right channels separately or together (see Section 5.1).

5.1Adjusting the Gain/Attenuation of the Channels

To adjust the amplifier gain or the attenuation:

1.Press the appropriate CHANNEL SELECTOR button.

That CHANNEL SELECTOR button illuminates and the decibel values of the selected channel appear in the dimmed LED displays (stored in the

non-volatile memory).

(When the LEDs are dimmed, you cannot change the gain or attenuation - the values are for observation only).

2.Press the LEFT LEVEL and/or the RIGHT LEVEL button.

The decibel values of the selected channel appear in the bright LEFT and/or RIGHT LED display.
