Sound Performance Lab 9530 manual Attenuator Atten./Limit VU In/Out

Page 17

When the tubes are active you can use the Attenuator controls to reduce the output level for each channel separately. Level changes due to processing can be compensated. The control characteristic has a very fine resolution before 0 dB (fully clock- wise).

The tube output section can be switched into a Limit mode for each channel separately. All levels exceeding 12 dB will be softly limited.

Limiting takes place due to the full saturation of the tubes in conjunction with a diode network. You may find that the top end is getting a bit duller due to the limiting. Use the High EQ to compensate for this. The Limit mode works very efficient when processing drums. To do so, insert the Tube Vitalizer into the drum-subgroup. Leave the unit in Attenuator mode when proces- sing complete mixes.

The VU In/Out switch lets you choose between either input or output levels to be displayed on the VU meters. When the status- LED is not illuminated the VU meter will show the input levels. On the other hand an illuminated status-LED indicates that the output level is displayed. The 0 dB mark on the VU is internally calibrated to +6 dB.

The Tube Vitalizer features a special relay circuitry that slowly 16 Tube Status builds up the 250 volts over a period of 45 seconds. Thereby the

lifetime of the tubes is increased by up to 4 times. In pre-maste- ring this circuitry garantees a reproducable sound for a long time. The tubes in use are E 83 CCs. The Warm Up-LED (red) illuminates after the main power has been switched on. After 45 seconds it switches to Active mode (orange-LED). If the Activate Tubes switch is pressed when switching the power on you will have no output signal until the Active mode is on. In the warm-up period you should not activate the tube section. The solid-states outputs are active immediately after mains voltage has been turned on.
