Operating the VP-885 To disconnect all outputs: • Press the ALL button, followed by the OFF button 7.3 Confirming Settings You can choose to work in the At Once or the Confirm mode. When the VP-885 operates in the At Once mode, pressing an output-input combination implements the action immediately. In the Confirm mode, the TAKE button must be pressed to activate the switch. The At Once Mode In the At Once mode, execution is immediate and actions require no user confirmation.
Operating the VP-885 2. Press the flashing TAKE button to confirm the action. The corresponding input number that is displayed in the STATUS 7-segment display no longer flashes. The TAKE button lights. To confirm several actions (in the Confirm mode): 1. Press each OUTPUT-INPUT combination in sequence. The corresponding input numbers that are displayed in the STATUS 7-segment display flash. The TAKE button also flashes. 2. Press the flashing TAKE button to confirm all the actions.
Operating the VP-885 Figure 15: Status Display 5 Seconds After Turn On 7.4.2 Status Display During Normal Operation During normal operation, the STATUS display shows which inputs are switched to which outputs (see Figure 16). Figure 16: Status Display During Normal Operation In the VIDEO mode, the display shows the video signal configuration. In the AUDIO mode, the display shows the audio signal configuration. In the AFV mode (see Section 7.5.1), the display shows both signal configurations. 7.4.
Operating the VP-885 To set the audio gain levels, see Section 7.7. 7.5 Choosing the Audio-Follow-Video or Breakaway Option You can configure stereo audio signal switching in one of two ways: • Audio-follow-video (AFV), in which all operations relate to both the video and the audio channels (see Section 7.5.1) • Breakaway, in which video and audio channels switch independently (see Section 7.5.2) 7.5.
Operating the VP-885 Figure 18: Configuration Button Numbering 7.6.1 Storing an Input-Output Configuration To store the current status in memory: 1. Press the STO button. The STO button flashes. 2. Press one of the INPUT/OUTPUT SELECTOR buttons from 1 to 8. This is the setup number in which the current status is stored. The memory stores the data at that reference. 7.6.2 Recalling an Input-Output Configuration To recall an input-output configuration, do the following: 1. Press the RCL button.
Operating the VP-885 To set the gain level of an input or output: 1. To enter the audio gain setting mode, do either of the following: Press either of the Audio Level buttons and press the required INPUT or OUTPUT SELECTOR button Press the required INPUT or OUTPUT SELECTOR button. If an OUTPUT is pressed, the display indicates which OUTPUT is selected by flashing the selected number. In this example, OUTPUT 8 is selected (see Figure 19) Figure 19: Status Display OUTPUT 8 Flashing 2.
Controlling the VP-885 When increasing/ decreasing the audio gain, the output signal level is higher/lower than the input signal level. Gain level values are relative since the audio input signal can be also adjusted independently of the output level adjustment. 7.8 Resetting the Unit To reset the unit: • Press and hold the Reset button on the rear panel while powering on the device. The unit resets and a Status display self-test is performed (see Section 7.4.
