playing different sources at the same time. As such, the installer can program the controls in
these rooms to send party input commands instead of the standard input commands. As
such, whenever someone selects CD in the living room, the dining room and entry foyer will
turn on to CD as well. There are no restrictions as to which rooms track which of the four party
presets or whether they do not track any. Rooms can track several party presets as well.
Rooms do not have to have a control to engage with a party function from another room.
Mute and Room Off/All Off
Each zone features three serial mute commands: mute on, mute off, and mute toggle. There
are also two additional commands involving audio, room off and all off.
Stereo Enhancement and Loudness Contour Filters.
Each zone provides the option to engage/disengage two filters. These filters are used when
either speaker size, placement, or room acoustics are less than perfect. The Stereo En-
hancement filter opens the sound stage between two speakers. If speakers are extremely
close together or in a position that is less than ideal, this filter may be of use. The Loudness
Contour Filter is used to enhance the bass output of speakers. If speakers have small bass
drivers or are in a position that baffles most of the bass information, this filter may be of use.
Both filter settings are encompassed in the Tone Presets.
Stereo & Mono
Here the P-16 is uniquely outfitted with both software and hardware options. Serially, one of
three preamplifier mixing options exist: stereo, mono input left, and mono input right. Stereo
(normally used), passes right and left channel audio inputs to the preamplifier stage. Mono
input left or right, pass only that channels information to the preamplifier stage. This feature
is useful if stereo recordings contain two completely different channels of information whereby
it is desired to eliminate one channel completely (language recordings).
While the software features may be of little use, the hardware mono/stereo feature is ex-
tremely important. While most rooms will most likely be set (hardware) for stereo (the P-16s
default state), it may be desirable for some zones to output a mono signal. Examples of such
areas may include hallways, galleries, outdoor areas, or even rooms that might contain only
one speaker (sauna). To down-mix to mono, the installer must alter a jumper-pin located on
the P-16 Module. This will require powering down the AVP-16, removing the P-16 Module,
locating the appropriate jumper (shunting pin) on the P-16 circuit board and inserting the
jumper. At this time, that zones audio output will be same on both right and left channels,
regardless of the separation of the input signal.
Variable and Fixed Outputs
The P-16 also permits any zone to have its output at either a fixed audio level (unprocessed)
or variable level (all previously mentioned preamplifier features). This is extremely useful
when desiring to include home theater systems or recording devices onto a Suite 16. Nor-
mally, the P-16s are inserted into an AVP-16 where zones 1-12 are set to variable (for multi-
room audio) and zones 13-16 are set to fixed (the line-level audio signal can be routed to the
input of a high-end home theater preamplifier, A/V receiver, high-end two channel preampli-
fier, TV audio input, or recording device). To alter any zone, you must locate that zones
appropriate jumper pins (shunting pins) which are located on the P-16 Module circuit board
and move them to the alternate setting. There are two jumper pins per zone (for left and right
channels). This will require powering down the AVP-16 and removing the P-16 Module.
