e R6 monitors use 5-way binding posts to connect to your amplifier.

(Figure 2)

Figure 2

This allows you to use a variety of different connections - ranging from bare copper wire to lugs to banana plugs. Any of these types of cable ends will make a good connection, but banana plugs will allow for quick disconnect whenever necessary and eliminate the problem of stray strands of copper between the terminals. On the amplifier side, use whatever type of end fits your power amplifier; typically bare wire, ¼" TS plugs, lugs, or banana plugs.

Use unshielded cables to connect your amplifier to your speakers.

f you are not sure if you have unshielded cables, contact your local

I music dealer to purchase the proper cabling.

Input (Right/Left), (+/-). Standard 5-way binding posts for accepting signal from your power amplifier. The posts will accept wire-gauge sizes as large as 14 gauges. KRK recommends using 14 gauges for the best sonic response.

22..33 AAmmpplliiffiieerr PPoowweerr RReeqquuiirreemmeennttss

KRK recommends using power

amplifiers capable of producing 50 -100 RMS watts per channel into 8 ohms. For best sonic results, a good rule of thumb is to use an amplifier capable of producing more than 1½ times the recommended power, rather than one that produces less than the recommended power. In fact, more speakers are damaged due to under-powering than to over-powering. An amplifier with insufficient power will create square waves when pushed beyond the "comfortable" running range (potentially damaging the voice-coils).

When hooking up passive (non-powered) speakers such as the R6 studio

onitors, you have several choices as to the proper type of cable. First, only use

m heavy 14 to 18-gauge unshielded cables. Sonically, the heavier 14-gauge cable is the best choice. Next, keep the speaker cable runs as short as possible. Just measure the proper length, leaving a few extra feet for later adjustments and easy access. Whenever possible, remember to use a heavy-gauge, unshielded cable, especially for long (over 20 ft) runs.

Also, avoid light-gauge "zip cord.” Light-gauge cables of considerable length not only rob amplifier power directly by turning it into heat, but they also reduce the damping factor of your power amplifier, (which can cause inaccuracies in the bass response of the speakers). Long cable runs can also introduce frequency response irregularities into the monitor system, especially around the crossover points where complex impedances exist.

CCaauuttiioonn

urn

t terminals are accidentally shorted together for even a few seconds.

If it is possible, use polarized speaker wire. This type of wire has one of the conductors marked with a ridge, color stripe, or other identifier such as copper- and white-colored conductors. This will allow you to easily hook up the speakers with the proper polarity, (which is very important for proper stereo imaging and bass response). Simply use the striped, ridged, red, or otherwise polarity-marked lead of the cable to hook to the hot (red, + or positive) terminal of the amplifier. Hook the other end of the cable to the red terminal on the monitor cabinet. Repeat using the black (negative) terminal of the amplifier being hooked to the black terminal of the speaker cabinet. Make sure there are no stray strands of copper poking out that might short to the opposite terminal. (Figure 2.1)

The close-field monitor, by definition, reduces room interaction. This can be

ompared to the conventional stereo configuration or the large monitor

c arrangement in a recording studio where sounds emanating from the monitor or reflecting off ceilings, walls, and floors greatly affect the sound quality. By shortening the path to the ear, the close-field monitor offers a tremendous amount of flexibility, allowing the sound to become less susceptible to differing room conditions. The ability to adjust the high frequency characteristics is equally important to help compensate for room irregularities and achieve the best sound accuracy.

A room that is heavily dampened would typically require a slight high frequency boost. Likewise, reducing the high frequencies can alter a reverberant room.

Placing the monitor close to a rear wall, sidewall, or a corner will reinforce the low frequencies. If you move them two to three feet away from walls and corners, you will hear less low frequency interaction (excluding any interaction with the mixing console).

33..22 PPoossiittiioonniinngg yyoouurr MMoonniittoorrss

Positioning your monitors corr Typically, they should be placed so that the listening position is fully “covered” with all monitors resting on the same horizontal plane. To test a monitor for its imaging capability, playback a song that includes acoustic instruments, to fully represent the entire sound spectrum.

You can adjust the angle of each monitor by listening for dead spots. Keep in mind, changing the angle or position of a monitor will change the way that you perceive your music. So lets analyze the following monitors’ configurations;

ectly in the studio is critical to their performance.

33..22..11 TTwwoo -- CChhaannnneell SSeettuupp

Near-Field Configuration

•

– In a control room situation, the monitors are often times placed on the meter bridge or in a close-field listening position. Initial placement starts by measuring out a simple equilateral triangle (all three sides equal in length) with the apex at the center of the listening position as an “overlay” for the stereo installation. In this configuration, the Left and Right monitors are each placed at a 60° angle, equidistant from the listening position. (Figure 3)

Figure 3

•

Mid-Field Configuration

– This configuration is similar to the close-field configuration. It is normally used with larger monitors, or when the monitors are too large or heavy for the meter bridge. This setup has the potential for a larger sweet spot and better spatial imaging. Make sure that the height of the woofer is above the height of the console. (Figure 3.1)

Figure 3.1

33.. PPoossiittiioonniinngg yyoouurr MMoonniittoorrss

33..22..22 SSuubbwwooooffeerr SSeettuupp

Note that KRK sub

woofers are optimized for use with KRK full range monitors. Begin by determining the best location for your subwoofer. The optimum setup is displayed in Figure 3.2. However, this setup may not be practical or possible in your room. Once you have set up your monitors, listen to program material that you know contains low frequency information. If your subwoofer has a phase switch, adjust the subwoofer to provide the highest frequency setting possible. Flip the switch back and forth to find the loudest setting. Then adjust the sub’s low pass filter so that it works in conjunction with the satellite’s high pass frequencies. When you have finished, readjust the level of the sub.

Figure 3.2

33..22..33 55..11 CChhaannnneell SSuurrrroouunndd SSeettuupp

Begin by placin

g the Left and Right front channels 30 degrees from the Center channel and equidistant to the listening position. The Left Surround (rear) and Right Surround (rear) channels should be placed 110 degrees from the Center channel. Their location should also be equidistant from the listening position. The subwoofer (Low Frequency Effects) channel is most effective when situated directly below the Center channel. If this is not possible, place the subwoofer just to the right or left side and below the Center channel. Ensure that the woofers are above the height of the console. (Figure 3.3)
