Description
Figure 1.1 KP-32 keypanel front view..
The RTS™ Model KP-32 Keypanel fits in a standard 19" rack and is two rack spaces high. It has
32 lever keys: 30 keys are for intercom talk/listen assignment; one key is for call waiting
response; and one key is for headset/microphone/program selection and volume setup. The KP-32
combines all of the programmable features of the KP9X Series Keypanels and the KP-12
Keypanel. It adds significant new features such as digital signal processing and binaural headset
operation with left/right assignment of audio signals. The KP-32 also introduces large, super-
bright, long-life fluorescent displays with adjustable brightness control, making it suitable for all
types of ambient lighting from direct sunlight to darkness.
Features
• Super-bright, fluorescent displays: Provide much better visibility and useable life than LCD
displays. A display saver mode with programmable scrolling message extends display life and
conserves power during periods of inactivity.
• 32 lever keys, with 30 keys available for full talk/listen configuration: Doubles the number of
channels over the KP9X series keypanels. Keys support both latching (hands-free) and
momentary (push-to-talk) operation.
• Enhanced programming keypad: Provides the complete KP9X keypad sequences, plus new
keypad sequences, plus an extensive scrollable menu system. Menus include helpful prompts
to walk the user through setup.

1-2 KP-32 User Manual
• Only 90 mm deep behind the front panel (approximately 130 mm with connectors): Perfect for
consoles, OB vans, etc.
• Digital Signal Processing (DSP): Improves microphone voice activation and limiting. Adds
new mixing, metering, and filtering capabilities.
• Binaural (5-pin) Headset Connector: Works with the DSP mixing feature. Lets you
independently assign intercom, microphone, and program audio to left or right headphone.
Note: monaural (4-pin) connector available as an option. For monaural operation, the mixer
lets you select which items are monitored in the headphones.
• Easy upgrades: Firmware updates can be received via the internet, for example, and then
downloaded to the KP-32 via the intercom connection. Ready for future communication
enhancements, including coax, fiber, and ISDN. (For further information, search for keyword
"firmware" in ADAMedit help.)

C HAPTER 2 I NSTALLATION
Option DIP Switch Settings
Switch 1: Latch Enable/Disable
Default setting = Open: Enable.
Description: An intercom key can always be turned on for momentary conversation by pressing
and holding the key during the conversation. There is also an electronic latching feature that lets
you tap intercom keys to turn them on or off. This permits convenient hands-free conversation.
However it can also result in a talk circuit being left on unintentionally. For example: A key that
talks to a public address system could be accidentally left on. Or an IFB key (a type of key
assignment that is often used by a director or producer to give instructions to a listener, such as a
news anchor during a television broadcast) could accidentally be left on, causing confusion for
the IFB listener. To prevent such accidents, the latching feature can be turned off.
Note DIP switch 1 disables latching for the entire keypanel. If you just need to disable latching for
selected keys, leave DIP switch 1 in the "Open" position. Then, disable latching for the desired
keys using the "D" check boxes in the Keypanels / Ports setup screen of ADAMedit.
Switch 2: Key Gain Enable / Disable
Default setting = Open: Enable.
Description: Enables or disables the Key Gain item in the Key Assign menu.
Switch 3: Screen Saver Enable / Disable
Default setting = Open: Enable.
With Screen Saver enabled, the KP-32 will shut off the display and enter a low-power state after a
few minutes of inactivity. The display reactivates instantaneously on incoming call or when the
keypanel operator actuates any control. As with all fluorescent and back-lit LCD displays, some
dimming will occur after many years of operation. Using the screen saver helps maximize the
display life.

2-2 KP-32 User Manual
Switch 4: Call Flash Timeout
Default setting = Open: 15 Second Flash.
Description: Whenever there is an incoming call and there is a talk key assigned to the caller, the
talk LED next to that key will flash. The flash can be set for 15 second timeout, or until the
caller's talk key is released.
Note Future versions of ADAM Edit and Zeus Edit will be able to override the Call Flash Timeout
setting.
Switch 5: Footswitch Enable / Disable*
Default = Open: Disabled.
Description: The optional Connector Module has a footswitch (GRP CALL) input. If the
footswitch is enabled (DIP switch 5 set to the "Closed" position), then keys that are latched on
will not activate until the footswitch is closed. Latched keys are indicated by winking green talk
LEDs (on time less than off time), and when the footswitch is activated, the LEDs provide the
normal talk-on indication.
Notes 1If the talk key is held down in Footswitch mode the channel will be activated until the user
releases the key. The use of this function does not require the footswitch to be used.
2If DIP switch 1 is set to the “Closed” position, nothing will latch.
3Individual keys can be set to non-latching via ADAM Edit. If this is done, the footswitch has
no effect on the keys that have been set to non-latching. Please see ADAM Edit help for more
information.
Switch 6: Network Mode Selection
Default Setting: Open (Mode 1)
Description: In the Mode 1 setting, the keypanel functions operate as called out in the main
portion of this manual. If the switch is closed (Mode 2), then the functions operate as outlined in
this manual with slight modifications. Any function that is affected by Mode 2 operation will
have an asterisk (*) by it. The changes/modifications to the functionality is called out in the
section titled “Mode 2 Operation”
Switch 7: Test/Debug
Default Setting: Open.
Switch 8: Test/Debug
Default Setting: Open.
Address Switch Setting
General Information
In Zeus, ADAM CS, and ADAM Intercom Systems, intercom ports are arranged in groups of
eight. All ports in a group share a common data port. Each KP-32 keypanel is uniquely identified
on the data port by the setting of its Address switch. The method of determining the proper
Address switch setting varies for each intercom system. Use the method for your intercom system
as described below. Then set the white pointer on the Address switch to point to the correct
setting.

2-3
Address Setting for Zeus
Intercom port connectors on the Zeus back panel are arranged in three groups of eight intercom
ports. For each group, intercom port connectors are labeled ID 1, ID 2, etc. When you connect a
KP-32 keypanel to Zeus, set the Address switch to match the corresponding ID number on the
Zeus back panel. Note that address switch settings 0, and 9 through F are not used.
Address Setting for ADAM CS
Each Audio I/O card contains 1 group of 8 intercom ports. However, the method of breaking out
the groups depends on the type of connectors on the back panel.
ADAM CS with RJ12 or DB-9 back panel:
The intercom port connectors are arranged in groups of 8. The first connector at the left for each
group is Address 1, the next is Address 2, and so forth.
Note Address switch settings 0, and 9 through F are not used.

2-4 KP-32 User Manual

Note Settings 0, and 9 through F are not used.

2-5
Address Setting for ADAM
Each Audio I/O card contains 1 group of 8 intercom ports. Determine the address setting from
Figure 2.1. To use the table, locate the intercom port number to which the KP-32 will be
connected. Then, read across to the "Address" column to find the Address number. Set the KP-32
Address switch to this number. Note: settings 0, and 9 through F are not used.
Connections
EXP. AND LCP Connectors
Connect from the Exp. connector on the back of the KP-32 to the Expansion 1 connector of an
optional EKP-32 Expansion Panel. Use the interconnect cable supplied with the Expansion Panel.
The Expansion 2 connector on the Expansion Panel can connect to a second Expansion Panel, but
no more than 64 intercom keys can be operated per intercom port.
Each LCP-32/16 adjusts the listen levels for 16 keypanel keys, and you can connect as many
LCP-32 panels as required to adjust all keys on the KP-32 and on an optional EKP-32 Expansion
Panel. An interconnect cable is supplied with each LCP-32. Connect the first LCP-32 to the LCP
connector on the KP-32. Connect the second LCP-32 to the first LCP-32, and so forth.
Note When arranging LCP-32 panels in an equipment rack, you should put them directly above or
below the keys they will be used to adjust.
Frame Connector
Use either of the Frame connectors (but not both) to connect to an intercom port of the intercom
system. The intercom port you connect to should agree with the address that you set previously.

after several minutes of inactivity. The display reactivates on incoming call or when the keypanel
operator actuates any control. DIP switch 3 enables/disables screen saver operation.
Note You can override the normal timeout period for screen saver operation and immediately place the
keypanel in screen saver mode. See "Service Menu, Disply Dim".
Selecting Headset or Speaker
Tap the Headset / Vol. Sel. key upward. The Vol. Sel. display alternates between Hdst and Spkr
with each key tap. The Headset LED lights when the headset is selected and is off when the
speaker is selected.
Note Future versions of ADAM Edit and Zeus Edit will be able to override the Headset or Speaker
setting.
Listen Volume Adjustments
By default, the Vol. control adjusts the listen volume for the speaker or headset, whichever
appears in the Vol. Sel. display. The level of auxiliary program inputs 1 & 2 (if GPI/O board is
present and Aux inputs are enabled) and the level of incoming audio from the intercom matrix can
be adjusted. To adjust a level, press the Vol. Sel. button until the desired source appears in the
Vol. Sel. display (
Aux1, Aux2, or Icom ). Then, use the Vol. control to adjust the listen volume. The
Vol. control defaults back to the speaker or headset after about one minute of inactivity of the
control. The minimum volume level for either the keypanel speaker or headset may be adjusted.
See “Service Menu, Min Volume”.
Note You can save the volume adjustments to be the power-up defaults using "Service Menu, Save
Cfg".

Intercom Keys and Displays
Alphanumeric Display Indications for Intercom Keys
Upper Case Letters: Upper case letters indicate keys that have any kind of talk assignment, with
or without a corresponding listen assignment. Example:
DIR1
Lower Case Letters: Lower case letters indicate keys that have only a listen assignment. Example:
dir1 .
Dashes
---- : Dashes indicate a key that has no talk or listen assignment.
Flashing Alphanumeric Display: This means the key is activated to talk to an IFB, ISO, or TIF.
Note The flashing alphanumeric display for TIF keys, remote IFB keys, and remote ISO keys can be
disabled by placing a check mark next to "Don't generate tallies for TIF and trunk use" in
ADAMedit (Options menu, Intercom Configuration, Options tab).
LED Indications for Intercom Keys
Note Future versions of ADAM Edit can override LED indications.
Talk LED Indications
The talk LED is the lower LED for each key. The talk LED indications are as follows:
Continuous Green*
Talk is on and the keypanel operator can be heard at the destination.
Continuous Red Talk LED & Flashing Display Alpha ("In-use")*
The key is off, but someone is talking to the destination. This indication is provided for any local
PL, IFB, ISO, or TIF key. It does not apply to remote IFB or ISO keys. This indication is provided
so keypanels operators know when critical director communications are occurring. If you activate
the key, either of two things will happen:
• If you activate the key and the talk LED turns continuous green, this indicates that you and the
other keypanel operator are both talking to the destination.
• IFB keys only: If the talk LED flashes red when an IFB key is activated, this indicates that the
other keypanel has a higher IFB priority and you cannot talk at this time.
Note The red "in-use" indication for TIF keys can be disabled in ADAMedit: In the ADAMedit
Options menu, select Intercom Configuration, then click on the Options tab. Place a check mark
next to "Don't generate talliesfor TIF and trunk use". Be sure to send the change to the intercom
system. Note that this will also disable the flashing alpha display when talking to remote IFBs or
ISOs as previously described.
Flashing Red Talk LED & Flashing Display Alternating Pattern of Alpha & (-**-)
("Busy")
You cannot talk at this time. This indication occurs when you activate a local IFB key that is
already in-use by a keypanel with a higher IFB priority. It also occurs when you activate any key
assigned to a remote destination, but there are currently no trunks available.
Note Flashing red is also the intended indication when attempting to talk to a remote IFB while
someone else with a higher trunk IFB priority is already talking. However, this will require
ADAM MC version later than 9.9.x and Trunk MC version later than 7.x.x. As of this writing,
these versions are not implemented. Regardless of the indication provided, you will not be heard
