1.1 Introduction, About this Owner's Manual Congratulations on your purchase of an Evolution System. We believe Evolution to be the most flexible, high performance loudspeaker collection available.
becomes the Evolution T5 tower . It employs the Evolution 12” aluminum cone woofer . The B5 cabinets are mirror imaged to allow for proper woofer orientation. B6 - The B6 subwoofer bass module mates with the M6 to form the T6 tower system. Designed for larger rooms, the mirror imaged B6 mod- ules each contain two 12” aluminum cone woofers.
1.3 Identifying Y our System T o the right is a chart by model, indicating the various components and accessory kits includ- ed with your purchase of either the T5/T6 tower or U1/U2 subwoofer system. The M5/M6 and P5/P6 are packaged individually with their required hardware and accessories.
2.0 Getting Organized. CAUTION: Some of the Evolution product is heavy . We recommend you enlist help in unpacking, assembling and moving the larger speaker components.

3.0 Speaker Placement Now is a good time to finalize your plans for speaker placement. This section outlines the important issues to consider in configuring your system for optimum performance. The M5 and M6 monitors are designed to per- form almost identically whether placed horizon- tally or vertically .
3.1 T wo Channel Stereo The diagram below illustrates the desired moni- tor and subwoofer placement for two channel (stereo) listening. If you are not using an Evolution tower or pedestal and are orienting the monitors vertically , try to place the M5 or M6 so the tweeters are at or near ear level.
3.3 Enhanced Digital Surround Formats Different surround formats use dif ferent num- bers of surround speakers. 5.1 systems use two surround speakers, 6.1 systems use three and 7.1 systems use four . Some A V receivers and separate Surround Processors are equipped with 6.
3.4 Center Channel The M5 and M6 monitors can be placed in a home entertainment center or directly on top of a TV as shown below . Remember , for proper center channel sound dispersion, the Monitor should be placed horizontally .
Evolution freestanding subwoofers offer tremen- dous flexibility in placement. The following sug- gestions illustrate a few of the possibilities avail- able to you.
4.0 System Assembly This section covers the assembly required for specific Evolution product configurations. The operations are simple and easy to accomplish quickly .
Step 2: NHT Third Foot for Center Channel Use The M5 and M6 cartons include a “Third Foot”, a support that stabilizes the monitor when it is mounted on a television. If the top of the televi- sion is shallower than the Monitor is deep, the rear of the Monitor will not be fully supported.
Step5: Attaching Monitor Grilles The M5 and M6 are designed to sound the best when the grilles are used (they may sound slightly bright if played without the grilles). T o install them, line up the four pins on the back of the grille with the four rubber cups located in the corners of the Monitor ’ s front baffle.
4.3 T5 and T6 T ower Assembly Depending on which model you purchased, you will now need the parts contained in either the K5 or K6 assembly kit. Step 1: Installing the Stabilizer Bars The aluminum bars attach to the bottom of the bass module to provide stability for the tower system.
Step 3: Attaching the Monitor Connection Harness The Monitor Connection Harness connects the Monitor ’ s speaker terminals to the terminal cup on top of the subwoofer module. This terminal cup is internally wired to the uppermost of the two terminal cups at the bottom rear of the sub- woofer module.
Step 6: Bass Module Orientation At this point you need to decide in which orien- tation to place the subwoofers. There are two options, woofers facing inwards or outwards as shown in the illustration.
Step 8: Connecting the Monitor Connection Harness to the Monitor Loosen the nuts on the binding post terminals enough to allow the spade terminals on the Harness to fit under them. Make sure you match wire colors for proper polarity , (red to red, black to black).
4.4 Assembling Monitors On Pedestals Step 1: Install Aluminum Stabilizer Bars Carefully turn the P5 or P6 bass module upside down on a soft surface, being careful not to scratch the paint. Find the four threaded holes on the bottom of the pedestal. Gently place the stabilizer bars over the threaded holes.
Step 4: Install Wire Channel Assembly The wire channel assembly for the P5 and P6 pedestals neatly routes the speaker wire down the back of the pedestal.
screw the metal spikes into the bottom of the aluminum stabilizer bars. T ighten the locking nuts by hand. Move to the other side and repeat the procedure. Be aware that wood or tile floors can be dam- aged by the spike’s sharp tip. Four small metal cups are included with the pedestal to fit under each spike and protect the floor .
5.0 Wiring Y our Speakers Before beginning to wire your system, we suggest you review the following guidelines and wiring dia- grams to find the Evolution system(s) you have pur- chased. T ools Required: NHT Wrench (included) Wire strippers T ape measure Speaker Wire (10 - 14 gauge) Component Interconnect Cables 5.
5.5 Wiring for Monaural Bass The B5 bass modules and the dual W2 sub- woofer cabinets require one additional wiring step. The speaker wire coming from the B5 or W2 cabinets must be connected in parallel at the A1 subwoofer amplifier . The Dual Subwoofer Adapter has been supplied with the A1 amplifier for this purpose (see illustration).

6.0 Connecting Evolution Electronics to Y our System. There are a number of methods by which you can connect the X1 Active Crossover and A1 Amplifier to the rest of your system. The method you choose will be determined largely by the surround components in your system.
ting will prevent low bass frequencies from reaching the Monitors. The removal of the low bass will make integration of the Monitors with your Evolution subwoofer easier and has the additional benefit of increasing the Monitor ’ s dynamic range and power handling capability .
Method 3 Use this connection method if you have a sepa- rate Surround Processor and Amplifier(s). - Connect the front Left and Right pre-amp outputs from your Surround Processor to the Left and Right inputs on the X1.
6.2 Power Connections The X1 crossover receives power via the LL-1 power supply . The A1 amplifier receives power via the detach- able IEC style power cord. Caution: Prior to connecting the A1 amplifier to your audio system, make sure that all your other electronic equipment is turned off or unplugged.

9.4 Power/Standby Mode The main power switch for the A1 is located on the rear panel and does not normally need to be used. The A1 has a standby mode that can be triggered internally or externally . On the rear panel of the A1 is a 3-position switch that deter- mines the trigger mode: 1) On: The A1 is always on.
9.6 System Status Indicators Located on the right hand side of the front panel are three LEDs. They are used to indicate the status of the A1 amplifier . P - Power LED (green) - indicates the A1 ampli- fier is on and in a ready condition. S - Standby LED (amber) - indicates the A1 amplifier is in "standby" mode.
10.0 Maintaining your system Y our NHT Evolution speakers and electronics require minimal maintenance under normal use. The cabinet may be cleaned using a soft cloth. There is usually no need to use fluids such as cleaners or wax to clean the surface of the speakers.
1 1.0 Evolution T echnology 1 1.1 Monitor T echnology NHT chose the word Evolution to describe our new products for two reasons. Evolution repre- sents our belief that loudspeaker design must evolve to meet the requirements of multi-chan- nel, digital media both technologically and ergonomically .
C) The internal midrange chamber features non- parallel internal surfaces that randomize stand- ing waves, eliminating comb-filtering and improving clarity and detail. The chamber is also sized to the midrange driver so that it is acousti- cally small.
When oriented horizontally , the null is directed at the ceiling or floor (depending on tweeter posi- tion) improving mid-range detail. 1 1.3 Boundary Switch A loudspeaker ’ s mid-bass response is very dependant on its room placement.
1 1.5 Orientation Independent Dispersion The Evolution monitors are optimized for use in either a horizontal or vertical orientation. This is achieved by means of the relative placement, size and crossover frequencies of the drivers.
