Tip:

flash yellow on the front panel, indicating a conflict on the main path. The PAV will also display the words tape loop on screen as a warning.

To avoid any possibility of running into a “Tape Loop” problem (where the PAV prevents you from choosing what you want, in order to protect the system from possible damage), simply select a non-recording source such as TV on the record path.

17STANDBY BUTTON

Pressing this button places the PAV in standby mode, turning off the display, disengaging all control functions, and turning off all outputs. The internal circuitry remains on in order to maximize performance on demand by vir- tue of all circuits remaining thermally stable. Lest you think this wasteful, you should know that the PAV draws less than power than a typical light bulb, whether in standby or fully on. The benefits of having it always warmed up and ready to go (and always able to respond to remote control commands) far outweigh the small amount of power used. We recommend using the rear panel power switch only when you will be away from the house for extended period of time, such as during a vacation.

There is another good reason for using the PAV’s standby mode. The PAV will generate a full-frame black video signal at its video outputs during standby, rather than passing no signal at all. This is particularly helpful with many projections televisions, since it gives the projector a “sync” signal to lock onto without calling for any light to be generated. This feature allows the projector to remain fully warmed up at all times without risking dam- age to the phosphors which create the projected light.
