RSX18A Features The Samson RSX18A powered subwoofer utilizes the latest technology in loudspeaker and power amplifier design. Here are some of its main features:

• Heavy-duty, 18" low frequency transducer with Butyl rubber surround

• Built-in 2000 Watt, highly efficient class-D power amplifier

• Dual balanced XLR inputs for mono or stereo operation

• Stereo balanced XLR full range and high pass outputs

• Heavy-duty, rear mounted casters

• Two large, steel carry handles

• 18 mm plywood construction, internally braced

• Durable textured black polyurethane paint RSX18A 7The following steps will help you set up your RSX18A active subwoofer.

• Unpack the RSX18A and included components. Be sure to save the packaging in case you ever move, or need to send the unit for service.

• Set the RSX18A subwoofer and satellite speaker(s) appropriately for the performance venue. The RSX18A has a 1 3/8" speaker pole receptacle, so you can mount a satellite speaker on top of the RSX18A using a satellite mounting pole (such as the Samson TS20).

• Turn the Level control on all speakers fully counterclockwise.

• Turn the Power switch to the OFF position on all speakers.

• Connect a line-level signal from your mixer (or other source) to the XLR Input jack on the RSX18A. If you are using a single subwoofer with stereo satellite speakers, connect the left and right output of the mixer to the stereo XLR Input jacks on the RSX18A.

• Connect an XLR cable from the High Pass output of the RSX18A to the line input of your satellite speaker(s).

• Plug the supplied power cable into an AC outlet. Note: Always make sure that the AC outlet used with this unit is configured with the correct voltage, as indicated on the rear panel of the RSX loudspeaker.

• Turn the Power switch on your RSX18A and satellite speaker(s) to the ON position.

• Run an audio signal (like music from a CD) from your mixer, and check that you are getting good level using the mixer's output meter.

• Slowly raise the satellite speaker(s) level control until you have reached a comfortable level. Then raise the RSX18A Level control until you have reached a level that sits well within the rest of the mix.

• If the volume from the RSX18A gets too loud, or you notice the Peak indicator blinking frequently, turn down the Level control on the RSX18A a little until the Peak indicator does not light, or only lights occasionally with signal peaks. Quick Start 8ENGLISH

ESPAÑOLITALIANO FRANÇAISDEUTSCHE

1. MASTER LEVEL - This control adjusts the overall signal level at the input of the

RSX18A's power amplifier. This control does not affect the signal sent to the Full Range and High Pass Outputs.

2. PHASE Switch - Use this switch to set the polarity of the amplified signal. In

the out (NORMAL) setting, there is no change to the signal. When the switch is pressed to the in (INVERT) setting, the signal's polarity is changed by 180°. The setting of the Polarity switch has no effect on the signal sent to the Full Range and High Pass Outputs.

3. PEAK Indicator -This red LED lights when the amp is near the clipping point. If

the Peak indicator lights frequently, turn down the Level control on the RSX18A subwoofer or turn down the signal at the source, until the indicator does not light anymore, or lights only occasionally with signal peaks.

4. SIGNAL Indicator - The green SIGNAL LED lights whenever signal is present at the

5. POWER Indicator - This LED lights RED when the amp is active.

6. INPUTS (L and R) - The RSX18A features electronically balanced female XLR

stereo line inputs. The left (L) and right (R) input signals are mixed together before they are routed to the internal amplifier.

7. HIGH PASS Outputs (L and R) - Electronically balanced male XLR stereo line

outputs, for sending the signal present at the INPUTS to your full range main loudspeakers. The signal is first processed by the internal 12dB per octave, 126Hz Linkwisz-Riley active crossover before reaching the outputs.

Controls and Functions RSX18A

98. FULL RANGE Outputs (L and R) - Electronically balanced full range male XLR stereo

line outputs. These outputs can be used to connect another subwoofer, or send full range signal to your main PA loudspeakers.

9. AC Power Inlet and Fuse

Sled - Connect the supplied standard IEC AC power cable here. Be sure to confirm and install the properly rated fuse when replacing the fuse or changing the operating voltage.

10. Voltage Switch - Slide to

change the operating voltage from 115 to 230 volts.

11. POWER Switch - Switches on

the RSX18A’s main power.

Controls and Functions 10ENGLISH

ESPAÑOLITALIANO FRANÇAISDEUTSCHE

In larger rooms, as well as in theatres and theme park installations (for low frequency special audio effects), two RSX18A's can be used in stereo. For additional low-end, you can daisy chain a pair of RSX18A subwoofers to each side of your speaker system. Stereo Sub Operation Before you start plugging in cables, you should take a minute to decide how you want to interface your new RSX18A. Most system set-ups fall into one of two categories: Stereo or Mono sub operation. In most cases, a common sub (or mono) bass setup is preferable. Low frequencies produced by a subwoofer tend to be non- directional. Since low frequency waves take so much space to develop, it is difficult for the ear to tell if sub bass is coming from the left or right side (unless, of course you’re in a very large room). Because of this phenomenon, just about all sub bass material is mixed in mono. Mono Sub Operation Configuring Your Speaker System RSX18A 11Phase and Polarity A speaker reproduces sound by converting electrical signal into physical vibration. This physical vibration, in turn, pushes air to create sound waves. When setting up your speaker system, the goal is to have all speakers moving in phase, with the in and out movement of the speakers synchronized. This produces an even sound across all audible frequencies. If the subwoofer is out of phase with the full range front of house speakers, you may notice decreased bass response, or even bass frequency cancellation where satellite and subwoofer frequency responses overlap. Many times this phenomenon is very subtle, but it can produce the effect of “holes” in the music, and diminished bass frequencies. Ideally, your RSX18A subwoofer should be positioned on the same plane as your satellite speakers. In reality, we know this is difficult, as there are restrictions when setting up a PA system due to space limitations, speaker stand configuration, or even speaker cabinet shape. To compensate for these obstacles, the RSX18A features a Phase switch, which allows you to reverse the polarity of the subwoofer relative to the source signal. This enables you to put the RSX18A in phase with the rest of your PA system, or 180° out of phase. To determine if the audio produced by your RSX18A is in phase with the rest of your PA system, play an audio track containing a lot of bass frequencies through your speaker system. Stand at a good listening distance, where you can clearly hear the audio from the subwoofer(s) and mains speaker(s), and listen until you believe you have a good gauge of the level of bass frequencies. Press the Phase switch on the RSX18A to reverse the phase by 180°, and move back to your original listening position (if possible, have someone else press the Phase switch so that you can stand in the exact same location). Compare the overall level of the bass frequencies between the two settings. The correct setting will result in more bass frequencies. If the situation allows, you can fine-tune the phase of your RSX18A to your satellite speakers by moving the relative position of the subwoofer closer or further away from the listening position.

Connections XLR to XLR Balanced XLR to Balanced 1/4-Inch The RSX18A features balanced inputs and outputs with industry standard XLR connectors. Whenever possible, use high quality balanced connections to other equipment to suppress interference. See the wiring diagram below for RSX18A connectors. Caster Installation

• Locate one caster and four each of the supplied screws and lock washers.

• Hold the caster in place and hand start the screws. Be careful to ensure that the screws are on the proper thread chase. Do not push down on the screws, as it could dislodge the internal thread- ed t-nuts.

• Use a screwdriver to tighten the four screws.

• Repeat the steps above for the remain- ing three casters.
