INTRODUCTION
Congratulations on your purchase of the Citation 5.0 DTS Audio/Video Controller or Citation 5.0 DTS upgrade kit.
Although the operation of the 5.0 DTS is virtually identical to the Citation 5.0 AC-3 only version, there have been
both operating and functional improvements made to the controller. This addendum covers additional set up
procedures and new features incorporated into the DTS version of the Citation 5.0 A/V Controller. The information
here should be use as a supplement to your original owner’s 5.0 owners manual
The Citation 5.0/DTS and new operating software Version 1.5 and above offer both performance and feature
improvements when compared to the 5.0 AC-3 only version. The new Digital Signal Processing (DSP) board used
in the DTS version is a later generation platform that replaces the original DSP circuits. In addition to DTS, this
new board offers improvements in digital audio quality and overall operational performance. Due to the modular
design of the 5.0, any 5.0 in the field may be upgraded to DTS by replacing the DSP board and upgrading the
operating software to Version 1.5 or above. Please refer to the separate installation instructions if you are
upgrading an original Citation 5.0 to the Citation 5.0 DTS.
A. SET UP
1. Perform a Data Reset - It is always best to perform a data reset when the 5.0 is first installed to assure proper
operation before initial programming and setup. Access the “System Reset” menu using the On-Screen Display
and follow the on-screen instructions to reset the system. Please refer to pages 59 to 61 of your owner’s manual
for a complete description to perform the System Reset.
IMPORTANT NOTE – When you perform a “System Reset”, the unit will go into a Standby condition. Press the
Front Panel “Standby” Button to complete the Data Reset. This action will bring the 5.0 out of standby and into
an operating Condition. The remote control “Standby” button will not operate after a reset until first brought out of
Standby using the front panel Standby button.
2. Power and Standby Buttons – Always use the “Standby” button on the remote or front panel during normal
operation when turning the 5.0 to an “ON” or “Off” state. The front panel Standby button will both power up and
power down the 5.0 where the Standby button on the remote will only power down the unit to a Standby condition.
The remote’s Watch, Listen, or input buttons 1 – 12 will power up the 5.0 to the desired source. The Master
“Power” button should only be used when hooking up new components, removing the power plug from AC, or
when leaving the home for extended period of time.
When placing the unit into a Standby condition, never use the power button on the front panel when the “On
Screen Display” reads “Power Off Standby”.
3. Video Detect - A line item has been added in the “Program Setup” menu so that the Video Detect circuit may be
turned “Off” from its normal “Auto” condition. Some video sources, including VCR’s, have a low “sync” output that
is below broadcast standards. If the Citation 5.0 detects out of spec sync levels, the unit may turn off the video
signal passing through the video board and display a blue screen. If you have a video source that intermittently

flashes to the blue display, turn “Off” the “Video Detect” feature. This feature should only be used for problematic
video sources.
B. IMPROVEMENTS IN NEW V1.5 SOFTWARE
1. Digital Audio Detect - The 5.0 will automatically detect PCM, Dolby Digital and DTS (where applicable)
bitstreams and switch to the appropriate digital surround mode. V1.5 includes the ability to easily override the
Auto Detect circuit by pressing the Dolby button on the remote. (NOTE - In addition to turning off this circuit by
pressing the Dolby button, Auto Detect may also be shut off in the “Program” menu for each source. This
circuit should normally be left “ON” under normal operating conditions.)
Overriding the Auto Detect circuit is generally used to manually force Dolby Pro Logic playback of 2-channel Dolby
Digital signals of some DVDs that Auto Detect 2.0 signals for Stereo playback. Auto Detect can be reinitiated with
a second press of the Dolby button, or by switching to another digital source or program.
Dolby Digital DVDs come in a variety of digital channel formats including, 1.0, 2.0, 3.0, 4.0, 5.0 and 5.1. These
numbers represent the number of audio channels carried in the DD bit-stream. Dolby Digital 2.0 (2-channel) discs
fall in one of two categories, those encoded for Dolby Digital Pro Logic playback and those non-encoded for 2-
channel Stereo only playback. Encoded discs should automatically play back in Pro Logic and non-encoded discs
will play back in Stereo.
A signal “flag” is embedded in AC-3 DVDs indicating whether a 2.0 bitstream includes a Dolby encoded signal for
multi-channel playback in Digital Pro Logic. 2-channel signals that do not have the “flag” will Auto Detect to play in
Stereo only. Unfortunately, many 2.0 recordings are Dolby encoded but do not have this flag. The Auto Detect
override allows the unit to be forced in the Digital Pro Logic mode, even though the disc indicates that the source
material is non-encoded.
What does this all mean? If you come across a Dolby Digital DVD that plays back in
2-channel Stereo only, you have two choices:
1. Press the Dolby button – This action will force Pro Logic playback of 2-channel DVDs and temporarily
disengage the Auto Detect circuit.
2. Press 6-Axis - Activating 6-Axis provides improved steering logic over Pro Logic and will not disengage the
Digital Auto Detect circuit. This mode is compatible for all
2-channel sources be they encoded or non-encoded. 6-Axis is a universal analog multi-channel mode available
for ALL sources both digital and analog, music and movies. We highly recommend this mode.
3. Level Matching between Surround Modes - Switching between Dolby and 6-AXIS will result in the audio
levels that are closer in level and channel balance. Although not exact, this is a great improvement over older
versions of software that played the 6-AXIS mode at a significantly higher volume level than Dolby.
4. Control the Citation 5.0 through the RS 485 BUS - The RS-485 BUS is now active and allows system
control with outboard RS-232 and RS-485 control systems. This BUS provides two-way communications and
is more comprehensive than IR only control. To communicate to the Citation 5.0 with RS-232 controllers, order
the Citation CCI RS232/RS485 interface module. Please contact Citation Technical Support for a copy of the
RS-485 documentation.
C. IMPORTANT NOTES UPON INITIAL INSTALLATION (NOT IN OWNER’S MANUAL)
1. Data Reset – It is always best to perform a data reset when the 5.0 is first installed to assure proper operation
before initial programming and setup. Access the “System Reset” menu using the On-Screen Display and
follow the on-screen instructions to reset the system. After the unit goes in to a Standby condition, press the
Front Panel “Standby” Button to complete the Data Reset. The remote control “Standby” button will not
operate during a reset. This process will avoid the “no digital audio” condition described below.

2. First Turn On - When powering up the 5.0 for the first time without first performing a Data Reset, it may be
necessary to push the “Standby” button once after the first time the unit is brought into an “On” condition. This
process of cycling the unit to “standby condition” completes the set up of the digital board. If this is not done,
the digital board may be out of “Sync” and no sound will be heard from digital sources. After this “Standby”
process is performed once, digital audio will be heard whenever a digital source is accessed.
3. Front Panel Reset - After a field software upgrade or board replacement, if ESD procedures are not used,
resulting in an Electrostatic Discharge into the unit, the 5.0 may lockup causing a loss of system control. In
addition, if you accidentally turn off the front panel IR in the “System Options” menu, a front panel system reset
may be needed to unlock IR front panel control.
To reset the system from the front panel:
1. Turn off the small power button so that the small green light is off.
2. Press and hold the (Watch –) and (Volume –) buttons simultaneously.
3. While pressing these two buttons, turn on the power to the unit, then release the hold on the (Watch –)
and (Volume –) buttons.
4. Press the Standby button on the front panel.
5. Go into the System Reset menu and perform another data reset from this menu.
