The Features:  
 
Satellite Design  
 
Sealed, damped elliptical enclosures made of high impact polystyrene (2-way systems) for minimized internal standing waves, natural reproduction.  
Magnetically shielded for placement near monitors.  
Midbass drivers with rigid fiber-composite cones, black urethane surrounds, inverted dust caps, and long-throw voice coils provide high output, low distortion, and uniform response at all levels.  
2-way design with metalized tweeter diaphragms for extended smooth HF response mated to exclusive Micro-Tractrix horns.  
High-definition crossover components for seamless driver transition and coherent phase response.  
New low profile pedestal bases with rubber feet attached for secure positioning.  
New spring-clip speaker wire terminals, which are designed to handle larger 18-gauge wire (supplied), allowing high current power delivery and lower distortion.  
Center Channel Design  
 
Magnetically shielded for safe placement on top or bottom of TVs and monitors.  
New spring clip wire terminals.  
Driver components are identical to main satellites for perfect channel blending and realistic imaging-- metalized tweeter diaphragm/Micro-Tractrix horn, and long-throw midbass drivers.  
High-definition crossover components for seamless driver transition and coherent phase response.  
Rear-mounted adjustment post for angle optimization for TV or PC monitor placement.  
Non-slip oval rubber feet for prevention of movement once properly positioned on top of monitor/TV.  
Low profile elliptical cabinet design (sealed, damped) ensures natural reproduction and baffle-height minimization (not taller than drivers require).
Control Tower  
 
Intuitive interface design with user-friendly level controls and display functions.  
Large main volume control has range of 1dB to 80dB, in 1dB increments. (These increments step in 3dB with faster knob rotation.)  
Precision (DVC) level controllers for unsurpassed clarity, low distortion, and minimum crosstalk. Theses devices allow broad dynamic range and precise channel level matching. Note: 80dB is the dynamic ?ceiling?, and the main volume setting will pre-determine the actual gain allowed in the center, sub, and surround channels. Note 2: Possible gain range settings for each channel are ?9dB to +15 dB and will be retained as the main volume approaches 80 dB. However new settings made at high volumes will only be allowed as the total reaches 80 dB. In other words, if the main volume reads 75 dB, the boost will be limited to +5dB, and if main volume is set to 80 dB (maximum), no boost is available.  
Digital numerical display rotates according to each function adjustment made. The display shows main volume by default. When a center, rear (surround), or subwoofer adjustment is made, the display automatically changes to the given channel mode. Once the adjustment is complete, the display reverts (after 3 seconds) to the main volume level.  
Combination power switch/headphone engage-speaker mute is positioned on lower left side of tower. This multifunction power switch will turn on and off the entire system when held for approximately two seconds. The current speaker volume level will be retained as long as the system remains plugged in. Headphone mode is engaged with a less-than-one-second tap of the button. The speakers are then muted, and the display reads ?HP? for headphones. The volume level for headphones is displayed and can be adjusted independently from the speaker level. Once the speakers are re-engaged with another short tap of this button, the original speaker volume is recalled. The last current headphone volume setting will also be retained as long as the system remains plugged in.
A note about headphone playback: if the signal going to the system is 4 channel, or up to full 5.1 signal, the headphone amplifier will downmix all of this available information into the two channels of the headphones. This will be especially useful for gaming.  
 
Backlit LED illumination for the main volume knob and digital display remains on when power is engaged to the system.  
9-pin DIN cable to the subwoofer carries all data to the subwoofer-based amplifier.  
MP3/portable audio player input for convenient desktop connection, with soundcard mixing function, through front L/R channels.
Subwoofer Elements  
 
High-grade MDF enclosure (medium density fiberboard, the reference speaker cabinet material) with 6th-order bass-reflex alignment.  
Front flared port for high velocity air movement, and dual side-firing active 8? subwoofer drivers (long-throw design). The tuned port enhances bass coupling and deep system tuning. Sixth-order alignment design allows high acoustic output and low distortion bass response while minimizing driver excursion.  
Dual eight inch long-throw bass drivers have 38 mm voice coils, vented pole pieces, and oversize magnets for maximum performance, power handling, and longer term reliability.  
The drivers are secured to the enclosure with eight T-nuts (each) resulting in an absolute air seal for heavy-duty operation and tight response.  
Advanced fiber-composite cone with inverted (concave) dust caps and durable urethane foam surround provide rigidity throughout the diaphragm structure, and long-throw, linear travel. The result: tight bass with definition and impact.  
Complimentary magnet structure positioning prevents damaging leakage of flux fields.  
Advanced modified sixth-order enclosure alignment delivers bass extension otherwise not realized in a compact subwoofer enclosure. This approach pays careful attention to optimum port tuning, driver design, cabinet construction, air seals, appropriate filtering, resulting in lower excursion to ensure low distortion on the loudest musical passages.
BASH Power Amplifier Elements  
 
Advanced technology BASH amplifier utilizing discrete MOSFET linear output transistors, smart dual-rail power supply and high current power capacity for low impedance/high peak load situations. The result: effortless dynamic headroom, which brings music to life. This results in a lack of dynamic compression in the subwoofer or satellites at the most extreme desired volume settings.  
Four discrete bridged MOSFET power transistors per channel for a total of 24 discrete power transistors. MOSFETs are the preferred power devices of high-end audio components due to their high current capacity and musical quality. This level of quality and excess is usually reserved for the finest home audio components.  
500 Watts of amplifier headroom provides abundant reserves into difficult low impedance loads. This is not necessarily for sheer volume, but more importantly for deep defined bass response, clear highs and midrange, and overall lowest distortion.  
Connections  
 
The amplifier inputs are designed for discrete analog 5.1 connectivity with the use of stereo miniplugs. The system will accept any combination, such as:  
2.0?the output of a laptop, VCR, TV, CD, or PlayStation 2/ X-Box (with RCA to Miniplug adapters)  
4.0?the output of a 4-channel soundcard  
5.1?the output of a 5.1 channel soundcard, DVD player (analog RCA jacks converted to miniplugs), or a 5.1 Dolby Digital decoder such as the Audio Tornado 5.1 (miniplugs). If certain channels of the system are not used (for example, the center channel or sub input with a 4-channel soundcard) the system intuitively knows to mix and send all the bass information to the subwoofer. It is important to remember to send a ?large speaker signal? (no bass redirection to LFE/Sub output) if you are using a 5.1 soundcard or Dolby Digital decoder to ensure that full bass signal response is reaching the entire system. Also note that in no way will the ProMedia 5.1 system be adversely affected by not utilizing all of the available channels.  
NOTE: the subwoofer input is designed to accept the ?.1? LFE (low frequency effects) signal from a soundcard or digital processor. This additional bass information is sent to the subwoofer amplifier channel and combined (within the sub amplifier channel) with the low frequency signal content from all other channels connected to the system, such as center and front/rear satellites. This bass management system within the ProMedia 5.1 further ensures that all available bass information will be reproduced with all the power and authority the system is capable of delivering. The benefit: the user does not have to worry about routing signals to the subwoofer?it is automatic.  
 
Speaker Wire  
The Klipsch ProMedia 5.1 is designed for the next level of ?PC Performance Audio.? We felt it was important to allow the end user to upgrade speaker wire, if so desired. However, we have included quality oxygen-free copper 18 gauge wire for the demanding enthusiast.
