In some installations, you may discover that some other company is trying to use the same infrared control codes used by the PAV, or vice versa. (This unfortunate circumstance has become more common in recent years thanks to the explosion of IR-controlled products in the home.) Fortunately, the PAV allows you to use any of eight different sets of IR codes, which are accessed by changing the “IR ad- dress” used by the PAV.

If you change the IR address of your PAV, your remote control will no longer operate the PAV until it is re-taught all of the new codes! Do not change this setting from its default value of 5 unless you must, in order to solve a conflict.

If you run into an apparent IR conflict where pushing one button on a remote control affects something seemingly unrelated, we suggest that you contact your dealer/installer for assistance. (The numbers 0 through 7 refer to Philips RECS80 addresses, a bit of engineering trivia your installer may need if your system is already using several of the available addresses, including the one we normally use in the PAV: 5.)

The remote trigger output on the rear panel of the PAV is normally used to auto- matically turn the associated Proceed AMPs on and off with the PAV. This is par- ticularly convenient when the amplifiers are located at some distance from the PAV, as may be the case when they are placed near the speakers (for example). In this application, you can simply leave it in its default setting, pulse.

If you need to turn on and off a power amplifier that does not include remote turn-on capabilities, the simplest solution is to use a product like the Niles IPC-6, which is an intelligent AC-outlet strip that can turn AC power on and off to a set of components based on the presence or absence of a level control voltage.

If you use the remote trigger output of your PAV with non- Madrigal products, it is important that those products provide current-limiting and ground isolation for this output. This isolation may be accomplished with opto-couplers or with low-voltage relays. Please consult with your installer prior to using the remote trigger output with products other than those designed by Madrigal.

Note that the remote trigger output of the PAV can support approximately 5 volts at 30 mA current.

Having completed the calibration of your PAV system, you may also wish to con- sider locking your settings to minimize the likelihood of someone inadvertantly changing your setup. This menu item can be found under the operate menu, which is found at the main PAV menu. (See page 47 for more information.)
