DEMONSTRATION FEATURES
1. Selecting Additional Speaker Pairs with PSBs
The number of speakers per product group that can
play at once is limited by the way you set the speaker
limit on the 980 module. The Access
™
System is capable of playing up to 4 pairs at once, but many receivers
are not recommended to play more than one pair simultaneously. Read your product’s documentation to
determine the setting you should use.
• To add a pair of speakers to the pair currently playing, LPress (press and hold about 1 second) the PSB of
the additional pair you wish to add until both pairs are playing.
• To turn any current speaker selection OFF, press its PSB.
• A short press on a new speaker selection cancels all previous selections.
2. Deselecting Products with PSBs
Turn any currently selected product OFF by pressing its PSB. The green LED goes out. If you deselect an in-
line product, such as an EQ, that product is replaced by a direct signal path if you have installed a bypass (for
more information, see “bypass” in the index).
3. A/B System Comparison
• A/B comparison may be performed on the 902/903, 906 control panels, or on the 905 IR Remote. For
detailed instructions, refer to the control panel User’s Guide.
• When you switch a component such as a source, the Access System engages our exclusive SilenTouch
™
circuit to mute the audio level briefly (0.15 seconds) during the switching process. This feature quiets all
switching noise.
4. TheftAlert
™
Protection
• TheftAlert
™
protects display products from unauthorized removal. When tripped, TheftAlert produces an
alarm though the external device chosen by your system installer. This feature is optional, and is available
through your Audio Authority
®
Account Manager. You may also install TheftAlert
after your initial pur-
chase. The special transformer required for this feature can be sent to you at no charge.
• Each switching module monitors the presence of its four products. 932 Speaker Selectors DO NOT have
this feature.
• You can control the TheftAlert functions via remote key switch, if installed, or from a Control Panel (if so
equipped). 902 and 903 Control Panels have an “arm” and “disarm” key sequence for TheftAlert. See your
Control Panel’s User’s Guide for more information.
• Set the switch in the OFF position to disarm TheftAlert while making product changes or to cancel an
alarm. Set the switch in the ON position to arm TheftAlert.
