Controls and Functions ENGLISHSETTING UP THE S•3-way Whether you are an experienced audio engineer or just starting out, the next sections of this manual will help you get going with your S•3-way. Now that you have unpacked the unit and have become a bit familiar with the front panel controls, you can follow the next sections of this manual to begin to set-up and operate your new crossover.Further on in this manual, you will find detailed wiring diagrams of various speaker system set-ups. For detailed diagrams of connector and cable wiring, see page 15 in this manual. MODE SWITCH The S•3-way can be configured to operate in several modes including Stereo or Mono 2-way, Stereo or Mono 3-way and Mono 4-way. In addition, the S•3-way has a special operating mode; 4-way LOW which is used for ultra-low sub woofer appli- cations. The Mode Switch, located in the center section of the unit, is used to select the operating mode. As you switch through the various operation modes, you will notice that several LED’s on the panel are also changing. These are the Mode Indicator LED’s and they help you keep track of the changing controls.

Because the S•3-way can be configured to operate in several different size sound systems, the crossover con- trols may be adjusted for the frequency division between low, and high, or low and low-mid, or high mid to high depending on the mode. On some crossovers, it is very difficult to get a quick visualization as to what controls are controlling what function. The S•3-Way solves this problem by employing it’s Mode Indicator LED’s over the Frequency and Gain controls. These provide quick identification of the frequency band that is under control. In the diagrams below, you can see what functions are under control when the associated LED is lit. Also, over each Gain control is an LED that illuminates indicating that frequency band has entered into Limiting. More information on using the Limiter can be found on page 10.

ENGLISH7 Operating the S•3-Way SETTING UP THE S•3-way FOR STEREO 3-way OPERATION The following operating example is for a Stereo 3-way system using 15" sub, 12" mid range and 1" compression driver and both the left and right side. There are systems examples for other set-ups including stereo 2-way and 4-way mono operation. CAUTION: Before you apply power to your speaker system amplifiers, be certain to set the frequency controls to the manufacturers recommended crossover points for the drivers or enclosures you are using. NOTE:

When running a loudspeaker system with one or multiple power amplifiers, it is highly recommended that you fol- low the LAST ON / FIRST OFF rule. When powering up your sound system, turn your power amplifier on last. When you power down your system, turn your power amplifiers off first. This will prevent any switching spikes you may get from other gear in your system, and help prevent unnecessary speaker damage.

• Connect both sets of inputs and outputs to the designated connectors on the rear panel. For a detailed cable-wiring diagram see page 15.

• Set the controls to the following positions:

L/LML/ML/HLIMLMIDMID350-8K

• Set the controls for the S•3-way’s Channel 2 to the same positions.

• Set the Power Switch to the ON position. ENGLISH8 BRIDGED PARALLELSTEREOBALANCED 0dBm

• Connect the mixer’s left output to the S•3-way’s CH1 (Left) input and the mixer’s right output to the S•3- way’s CH2 (Right) input. Now connect the S•3-way’s CH1 (Left) Low Output to the left input of the low end power amp, CH1 (Left) Mid Output to the left input of mid-range power amp, and (Left) High Output to the left input of High power amp. Now make the same connections for the S•3-way’s CH2(Right) and amplifiers right side. ENGLISH9 SETTING UP THE S•3-way FOR STEREO 3-way OPERATION (Continued)

• Lower your power amplifier outputs to all the way off. Turn on all your power amplifiers. Run an audio sig- nal (like some music from a CD) through your mixer and raise the output faders until you see the Input Meter LED’s begin to light.

• Slowly raise the S•3-way’s Input Gain until the Input Meter reads 0dB.

• Now raise your power amps to their normal operating level.

• Slowly raise the S•3-way’s Ch1 (Left) Low Gain to 0 and then raise CH2 (Right) Low Gain to 0.

• Slowly raise the S•3-way’s Ch1 (Left) Mid Gain to 0 and then raise CH2 (Right) MID Gain to 0.

• Slowly raise the S•3-way’s Ch1 (Left) High Gain to 0 and then raise CH2 (Right) HIGH Gain 0.

• Now use your ears to adjust the balance between the low, mid and high end. You can continue to raise the Gain controls as you fine-tune the system. Watch the Peak Meters on your power amplifiers to ensure that you re running a clean signal. Operating the S•3-Way DELAY The S•3-way features a delay that can be set for up to two milli seconds of delay time for time aligning speaker stacks.

The S•3-way incorporates a HPF (High Pass Filter) which when engaged, activates a low frequency roll off at 25 Hz. By using the HPF you eliminate the sub-sonic frequencies sent to the low frequency power amplifier. Since the amplifier will try to reproduce these frequencies with the HPF is off, in most cases the result is simply wasted energy. By using the S•3-way HPF you send just the frequency you want to reproduce to your low frequency amplifiers and speakers.

STEREO/MONO CROSSOVER The Samson S•3-way features a variety of control functions that offer the sound engineer advanced control over a speaker system. The next section is a description of the control functions and how they are used to improve the overall sound of a sound reinforcement system. ENGLISHOperating the S•3-Way

PHASE SWITCHES The S•3-way incorporates individual PHASE reversal switches on each frequency band. When engaged, the LED illuminates indicating that the selected output is now 180 degrees out of phase. GAIN

H MIDH MIDPHASE MUTE

MUTE SWITCHES The S•3-way features Mute switches on each frequency band. When engaged, the LED illumi- nates and that channel output is turned off. The MUTE switches are convenient for trouble shoot- ing or for simply listening to each speaker sec- tion separately.

Many of today’s popular speaker enclosures feature Constant Directivity Horns. The S•3-way’s CD EQ switch can be activated to apply a special equalization curve for smoothing and adding air to the high end of a loudspeaker system.

For easy operation of mono subwoofers, the S•3-way provides a MONO SUB switch. When activated, the low frequency band of Channel One and Two are summed together. The common low frequency signal is present at both Channel One and Channel Two’s Outputs. LIMITER A Limiter is a specific form of a compressor configured to prevent peaks and for general overload protection. The S•3-way offers a Multi-Band Limiter with vari- able Threshold control. The operating range of the Limiter is from -5 to +18dB and when engaged, protects against signal peaks and overloads.

Unbalanced 1/4” Connector Balanced TRS 1/4” Connector XLR Balanced Wiring Guide ENGLISHSETTING UP THE S•3-way USING A REAL TIME ANALYZER SETTING UP THE S•3-way USING A REAL TIME ANALYZER A REAL TIME ANALYZER (RTA) is an especially useful tool for setting up your crossover, as it will enable you to set parameters like DELAY and LEVEL more accurately. Some Audio Engineers can use their ears to tune a loudspeaker system. Some will even use the crossover to create the over-all system curve using the crossover like an equalizer. For the rest of us, an accurately set crossover with a flat response is the best way to start and using a RTA is the best way to get there. Using the RTA to Set DELAY Time. In the real world, no single or multiple speaker system is perfect. If there were such a perfect system, it would more than likely be comprised of a single transducer that alone could faithfully reproduce the entire frequency spectrum. Because no such system exists we have to deal with the problems associated with multiple transducers. The first problem that you will encounter, whether you know it or not, is time travel. That’s when the S• 3-way’s delay circuit becomes especially useful. Ideally, the sound reproduced by each driver in the loudspeaker system would be traveling through the air ultimately reaching the listeners at the same time. To accomplish this in a system using multiple dri- vers or enclosures, the voice coils of all the drivers would have to be lined up on the same vertical axis. This is very difficult to achieve in many cases because of the physical size of the different components, and the position of the drivers in their enclosures. It is not uncommon to have a physical distance of 2” to 24" or more between the low and high frequency drivers. For example, front loaded low frequency dri- vers and compression drivers mounted on a large horn. With no correction, the low frequency signal can be traveling through the air 2" to 24" in front of the high frequencies and thereby reaching the listeners at different times. Although the delay time between the low and high frequency signal may be relatively small, the negative effects can be substantial. The problem is that both drivers are reproducing frequen- cies at and around the crossover point, which arrive at the listeners at different times. Typically, the resulting problem is comb filtering or cancellations at the crossover frequencies. The S• 3-way features a DELAY control allowing you to dial up-to 2 milliseconds of delay. By using a RTA and the S•3-way’s DELAY you can time align the drivers in your system and minimize the possibili- ties of comb filtering. Now follow these steps, separately, for both the left and rights sides of your loud- speaker:

• Set the crossover to the desired frequencies and press all the Mute switches to the ON position, turning all of the S •3-ways outputs off. Position your measurement microphone approximately 15 feet from your loudspeaker array, halfway between the low and high frequency drivers. Now turn all the GAIN controls to the fully counter clockwise position.

• Play a sign wave tuned to the crossover frequency, or connect a pink noise generator to your loudspeaker system either from your mixer or in the S •3-way’s input. Now turn off the Low Frequency Mute switch and adjust the S• 3-way’s INPUT GAIN to "0”. Adjust the LOW GAIN control so that the signal is playing at a loud, but not too painful level. Make sure you only hear sound from the low frequency driver.

• Adjust the level control of the RTA until it reads OdB at the crossover frequency. Now press the LOW MUTE switch turning off the low frequency output.

• Turn off the High Frequency MUTE switch and turn up the High Frequency Level control until the RTA reads 0dB at the crossover frequency.

• Now, press the LOW MUTE switch again turning on the low frequency output. Notice the reading on the RTA at the crossover frequency. If the reading is 0dB, there is no need to adjust the delay time and you can assume that the speakers are in phase. If the RTA reads less than +3dB you’ll need to delay the low frequency.

• While watching the RTA display, slowly turn the DELAY control counter-clockwise until the dis- play reads +3dB. Setting the GAIN Controls Using a RTA It is critical to set the GAIN output controls so that all the frequency bands combine to create an over-all flat system response. Using a RTA to set the GAIN control will make it much easier for you to accomplish a flat system response. Follow the steps below, separately for each side of your system, to set the GAIN controls using a RTA.

• With the crossover set to the desired frequencies, press all the Mute switches to the ON position, turning all of the S•3-way’s outputs off. Position your measurement microphone approximately 15 feet from your loudspeaker array at a level ranging from your chest to your ear. Now turn all the GAIN controls to the fully counter clockwise position.

• Play a sign wave tuned to the crossover frequency, or connect the signal from a pink noise gen- erator to your loudspeaker system, either from your mixer or directly in the S•3-way’s input. Now turn off the Low Frequency Mute switch and adjust the S•3-way’s INPUT GAIN to "0’.

• Adjust the LOW GAIN control until the RTA has an average reading of OdB at and below the fre- quency of the LOW crossover point.

• Turn off the Mid Frequency Mute switch and turn up the MID Frequency GAIN control until the RTA reads the same average level in the MID band.

• Adjust the HIGH GAIN control until the RTA has an average reading of OdB at and above the fre- quency of the HIGH crossover point. At this point all of the frequency bands will be at the same level and your system will have a flat response. After setting the levels you can use a graphic equalizer, like the Samson E62I, if you want set a particular response curve to tune the speaker system for a specific sound.
