Harman Kardon CITATION 5.0 Reference Manual page 2

A turn on/off circuit is activated by a low voltage trigger signal — available from the Citation 5.0.
When used in multiples, the first 5.1 turns on and stabilizes and then sends a trigger signal to the
next amplifier in the chain. This prevents circuit breaker overload that would normally occur if
multiple amplifiers all turned on simultaneously.
High quality mechanical construction. Each 5.1 is constructed from heavy gauge steel and
aluminum chassis components. The fascia is machined from aluminum plate, machined, brushed
and then anodized. A complete 5.1 weighs over 60 lbs (28 kg).
High quality gold plated input/output connectors are used for audio input and speaker outputs.
The 5.1 is CE/FCC/UL/CSA approved for worldwide sales. Available in 100-130 or 200-230 Volt
50/60Hz versions.
The 5.1 is THX Conditional Use Certified when used to drive Citation or Fosgate Audionics Dual
Drive dipole surround speakers.
5 Series Loudspeakers
The individual loudspeaker models that form the 5 Series have been manufactured employing purposely
designed drivers — selected for their ability to best meet the design criteria. The 5.2 LCR and the 5.4
subwoofer are finished in a semi-gloss black lacquer finish applied over oak veneer. The 5.3 Dual Drive
dipole is available in a matte black finish or eggshell white.
5.2 LCR
This compact mains speaker can deliver high output beyond its proportion to cabinet size. The 5.5 inch
mid/woofer has a three inch voice coil! This robust design can provide very high sound pressure levels
in typical domestic listening rooms.
The one inch soft dome tweeter is step aligned with the woofer/mid. A 2.5kHz crossover provides a
seamless transition from one driver to the other and a coherent sound stage. Strips of wool padding
around the perimeter of the tweeter mounting area reduce diffraction effects for improved imaging and
smoother response.
The 5.2 must be used with a controller, such as the Citation 5.0, which incorporates an electronic
crossover.
5.3 Dual Drive Dipole
A look at the rear panel of the 5.3 provides an immediate indication that this is no ordinary surround
speaker. Two sets of input terminals — one for each array and each driven by a separate output from the
5.0 controller and 5.1 amplifier — enable the 5.3 to deliver the best of all worlds. It can provide the
razor sharp surround channel imaging that only a point source radiator can deliver, or it can provide an
enveloping diffuse soundfield that is characteristic of a true dipole.
Years ago, Citation design staff determined that one type of surround speaker could not deliver the best
performance with varying program sources. As an example, some music is best suited to subtle surround
enhancement — the type of enhancement provided by a diffuse soundfield. Other varieties, such as rock,
new age, live concert performances, are enhanced by the strengthened imaging that only a point source
speaker can deliver. And likewise with film soundtracks. Some films employ subtle, ambient surround
tracks — best served by a diffuse dipole — while others of the action/adventure genre are often
enhanced with point source radiators.
While we at Citation cannot make the listening decision for you, we can give you the tools for the best
surround playback — our Dual Drive Design. Everything happens transparently:
Select Dolby ProLogic and the signals sent to each array of 5.3 are out of phase (polarity) with each
other and create a diffuse soundfield which enhances monophonic surround tracks.
Select 6-Axis, Dolby Digital or DTS™ and in phase signals are sent to each array — creating a point
source soundfield. The 5.0 menu system also allows you to customize the soundfield of various surround
modes.
Besides making the listening experience more real and exciting, the 5.3 provides other benefits as well.
Because the signal levels to each array can be raised or lowered independently of each other during the
setup phase of installation at the 5.0 controller, a pair of 5.3 dual drive dipoles do NOT need to be
symmetrically mounted in the room. They don't even have to be mounted flanking the listening area like
