PLB-AS16 16 x 16 Stereo Audio Switcher
Product Information
PHAST Landmark Audio Switches distribute stereo program and monaural intercom audio for
whole-house sound integration. Operating via the PHASTLink data bus, Landmark Audio Switches
respond to keypads, panels, or system automation-routing any input to any output.
Each channel has automated audio pre-amp processing for volume level, balance, bass, treble,
loudness, and muting. Interactive feedback is provided for these parameters, plus routing and signal
sensing. Each input has signal sensing capability, allowing program events to be triggered by an
input signal state.
Inputs can be configured as a stereo pair, or as a mono input, such as for an intercom input. The
PLB-AS16 provides programmable switching capabilities for 16 stereo outputs and 16 stereo
inputs (or 32 mono inputs).
16 full audio zones are supported. Each output is an audio zone, and each zone can select any input,
even if that input is already selected by another audio zone.
Landmark software now allows you to automatically software-connect any audio source to inputs
on ALL of the Audio Switches in a system. This allows multiple Audio Switches to share the same
sources, increasing the number of audio zones in a system that use those sources.
Product Information
Each Audio Switch provides 16 audio zones. Intercom capabilities are limited to one Audio Switch,
with a maximum of 16 intercom zones (out). Landmark software does not limit the number of
Audio Switches in a system, although switching all zones on multiple Audio Switches will slow
down the switch response time. Landmark audio switches can be rack or shelf mounted. The rear
panel of the PLB-AS16 is shown in .

Connection and Power-Up Procedure
1. Read the Safety Instructions section at the beginning of this document.
2. Plug the PLB-AS16 power cord into a matching and properly grounded 115 or 230 VAC
outlet.
Verify wether you are using the domestic or international version by checking the
serial number.
The serial number for the domestic version starts with "992-10".
The serial number for the international version starts with "992-11".
3. Turn the PLB-AS16 on. The power switch is located at the right side of the rear panel. On
power-up, 16 "zone-active" LEDs display at the center of the front panel.
PHASTLink Ports
There are two PHASTLink ports on the left side of the rear panel of the PLB-AS16. Usually you
will use only one, but the second port allows you to daisy chain the Audio Switch to other
PhastLink devices, such as additional Landmark Audio Switches or Audio Amplifiers.
It does not matter which PHASTLink port you use; they are both functionally identical.
TERMINATE any unused ports.
Line-Level Inputs
There are 32 stereo line-level RCA-type input jacks on the rear panel of the system unit , providing
16 stereo pairs of audio input.

Line-Level Outputs
There are 32 stereo line-level RCA-type output jacks on the rear panel of the system unit, providing
16 stereo pairs of audio output.
Note on Intercoms
An RCA intercom cable from an PLH-MIC Mic Hub may plug into either the Right In or Left In
connector for an Audio Switch channel. In either case, the Right Out and Left Out for that channel
will both carry the same mono signal. In other words, the Right Out and Left Out for a channel
always comprise one audio zone.
It is possible to connect one intercom to a Right In and another to a Left In, but only one of those
intercoms can be switched to the audio zone output at any given time.

PHASTLink Cable Information
This section contains information that you will need to make PHASTLink cables, plus general
information on connecting PHASTLink devices.
PHASTLink cables are used to connect all PHASTLink-compatible devices, including keypads,
dimmers, J-box IR devices, amplifiers, audio switches, etc. PHASTLink uses a standard 10BaseT
connection (i.e. Cat 5 wire and RJ-45 connectors), and the wire should be connected in the standard
manner illustrated in the following table. If the standard EIA/TIA 568A color code is followed,
wiring problems will be minimized.

It is important that the correct pairing is observed. Transmit, Receive, and Mic
need to be on twisted pairs. Splitting pairs (e.g., using a white/green wire with a blue/
white wire for transmit) will result in increased crosstalk, and may result in bus failure
or noise on the intercom.
The system comes with a 15-port hub built into the PLB-CF10 cardframe. The maximum length of
PHASTLink wire per port is 1,000 feet.
Each PHASTLink device has two RJ-45 jacks to allow multiple devices to be daisy-chained on one
PHASTLink port. Remember to always terminate the unused RJ-45 jack of the last device (or the
only device) in a chain of PHASTLink devices (see Building a Double 120-ohm Terminator for
details).
The limit for each home run is 500 mA or 10 PHASTLink devices, whichever comes first
(FIG. 4). Extra hubs can be added to provide additional ports.
Only one Landmark LCD keypad (i.e. DMS or IMS) can be used per port, so always
home-run each keypad.
Some PHASTLink devices (particularly those devices that require two-way
communication to the Master) have relatively high bandwidth requirements. These
devices (including SAM modules, the PMB-TCC Remote Television Control Center, and
ITI Printer/Automation Module) should also not be daisy-chained.

Building a Double 120-ohm Terminator
For optimum performance, you must install a double 120-ohm terminator in the unused RJ-45 jack
of the last device (or the only device) in a chain of PHASTLink devices.
Up to 15 PHASTLink

PLB-CF10 Cardframe
To build a double 120-ohm terminator:
1. Install a 120-ohm resistor (1/4-watt or larger) between pins 1 and 2 of an RJ-45 connector.
2. Install a 120-ohm resistor (1/4-watt or larger) between pins 7 and 8 of the same RJ-45
connector.
When connecting Landmark keypads that will be used as intercoms, the Microphone Hub taps off
the intercom audio signal carried on the PHASTLink cable from that keypad.
Landmark LCD keypads must connect directly to a Landmark Hub (or Microphone Hub). Due to
power requirements and/or the need for a separate microphone line for each keypad, they cannot be
daisy-chained to other LCD keypads. For maximum performance and reliability, a Landmark
keypad should be the only device on a home run to a port. PHASTLink devices cannot be wired in
a star configuration (see FIG. 5).
