Frequently Asked Questions - S.3way SAMSON

How to configure the S.3way in 3-way stereo mode?

Set the mode selector to ST 3 W. Use the first FREQ potentiometer of each channel to adjust the crossover frequency between lows and mids (L/M indicator), and the second for mids/highs (M/H indicator). Adjust the gains with the corresponding potentiometers (LOW, MID, HIGH).

What is the function of the delay (DELAY)?

The delay allows time alignment of the low-frequency drivers relative to the high-frequency drivers, compensating for differences in voice coil distance. Adjust it from 0 to 2 ms to avoid comb filtering and phase cancellations at the crossover frequency.

How to use the Mono Sub function?

Press the MONO SUB button. The low-frequency signals of channels 1 and 2 are summed and sent to both low outputs. Useful for a mono subwoofer.

What does the CD EQ button do?

It applies a special equalization curve that softens the high-frequency response for constant directivity horn speakers, improving clarity and sonic fullness.

How to adjust the limiter?

Press the LIMITER button and adjust the THRESHOLD potentiometer from -5 to +18 dB. The Peak indicator lights up when the limiter is active. Adjust it to protect the speakers without distorting the sound.

What is the recommended power-on sequence?

Power on the S.3way before the power amplifiers. For power off, turn off the amplifiers first, then the S.3way. This avoids unwanted noise and protects the speakers.

How to interpret the frequency band indicators?

The indicators above the potentiometers show which band is being controlled. For example, in 3-way stereo mode, LOW, MID, and HIGH light up for the corresponding gains, and L/M, M/H for the crossover frequencies.

Can the S.3way be used in 2-way stereo mode?

Yes, select ST 2 W. The first filter sets the crossover frequency between lows and highs. Adjust the gains of the LOW and HIGH bands.

How to perform time alignment with an RTA analyzer?

Place a microphone 4.5 m from the speakers. Inject pink noise at the crossover frequency. Mute the bands one by one, adjust gains to obtain 0 dB on the analyzer. Then activate both bands and adjust the delay until +3 dB at the crossover frequency.

What to do if the unit does not power on?

Check the power cord and the external fuse (located on the IEC connector). If the fuse is blown, replace it with an identical model. If the problem persists, contact Samson technical support.

Operating the S•3-way

SETTING 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 applications. 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.

PHASE MUTE HIGH MID H MID H MID LOW 201-10 E 10 J/LOW INPUT GAIN DELAY GAIN 0 -5-6 -12-12 dB 0 1 2 0 -5-5 dB HPF n18ac dB R S 5DC

FREQUENCY BAND & LIMIT INDICATORS

Because the S•3-way can be configured to operate in several different size sound systems, the crossover controls 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.

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: LAST ON / FIRST OFF

When running a loudspeaker system with one or multiple power amplifiers, it is highly recommended that you follow 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:

• Lower your power amplifier outputs to all the way off. Turn on all your power amplifiers. Run an audio signal (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.

S•3-way Controls

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.

HIGH PASS FILTER

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.

SETTING 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 drivers 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 drivers 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 frequencies 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 possibilities of comb filtering. Now follow these steps, separately, for both the left and rights sides of your loudspeaker:

• 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.

SETTING UP THE S•3-way USING A REAL TIME ANALYZER

• 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 display 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 generator 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 frequency 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 frequency 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.
