Chapter 1: Introduction 1
2 GSR Speakers Guide
Chapter 2: Setups
This chapter shows how to set up and power your GSR
speakers, and provides audio connection diagrams of a few
typical setups.
Flown
Speaker Positioning
For suspension mounting or “flying” your GSR10 and GSR12,
there are five (5) M10 flypoints located on the top, bottom,
and back of the cabinet. Simply thread in a corresponding
M10 eye-bolt, and you’re ready for “flying” your GSR
full-range cabinets.
GSR10 and GSR12
To access the M10 flypoints:
GSR speakers can be positioned standing upright, as a floor
wedge monitor, flown, or mounted on a standard speaker
stand (not included).
„ On the top, bottom, and rear of the cabinet, remove the
threaded caps that cover the M10 inserts.
Standing
When positioned on the floor standing up straight, the speakers can be stacked (never stack more than two GSR speakers).
When stacking a speaker, make sure its feet align properly on
the top of the lower speaker using the interlock feature on the
tops of the GSR10 and GSR12 cabinets.

Mounted
Each GSR10 and GSR12 features a 36mm pole mount receptacle on the bottom, enabling you to mount the speaker on any
standard 1 3/8-inch speaker stand. After mounting a speaker
on any pole or stand, be sure to hand-tighten the rear stabilizing screw on the back of the cabinet. This ensures the cabinet
does not move or turn during performance.

Floor Wedge
GSR10 mounted on a pole stand
The GSR10 and GSR12 also have 45° angled sides that let you
lean it back on itself, like a typical “floor wedge” monitor.
The GSR18 subwoofer has a 1 3/8-inch pole mount on its top,
letting you use a standard speaker pole to mount a GSR10 or
GSR12 directly on top of a GSR18.

Chapter 2: Setups 3
GSR18
The GSR18 should be placed on the floor or stage. Do not
stack speakers directly on top of the GSR18 unless you are using the pole mounts and one GSR10 or GSR12.
AC Power
(All GSR Models)
GSR speakers provide automatic input voltage sensing (110V
to 240V).
To connect power to a GSR speaker:
„ Connect the included AC power cable to the AC Input in
the back of the speaker. Connect the other end to your wall
outlet or other power source.

Figure 1. Microphone connected to the Mic input (GSR12 shown)
To use a GSR12 or GSR10 with a single microphone:
1 On the back of the speaker, turn the Level control down (counter-clockwise to Min). Make sure power is Off.
2 Using an XLR or TRS cable, connect a dynamic microphone to the Input on the back of the speaker.
3 Make sure the Mic/Line button is set to the Mic position.
4 Rotate the Mode knob to select Voice mode (you can change this later, but we recommend it for voice and speech). For more
information on the tuning presets, see “Modes for Speaker Presets” on page 11.
5 Turn the speaker on using the Power switch.
6 Speak into the mic while you slowly raise the Level. Don’t point the microphone at the front of the speakers to avoid feedback.
7 If desired, press the HPF 75Hz button to engage the high-pass filter. The HPF (high-pass filter) can reduce or eliminate rumble
and other low-end noise.
Chapter 2: Setups 5
Daisy-Chaining Multiple GSR10 and GSR12 Speakers
GSR speakers have outputs as well as inputs.
The “Thru” output XLR jacks are there to let you “daisy-chain” several speakers from one source. In this type of setup, a mono
source (whether from a single microphone, a mixer, or other device) is connected to the first GSR speaker’s Input. Then, an XLR
cable is connected from that speaker’s THRU jack to the Input on the next GSR speaker as shown in the figure below.

Figure 2. Two GSR12 speakers connected in “daisy-chain” style, amplifying a mono signal from a mixer.
To connect multiple GSR speakers by daisy-chaining:
1 On the back of the speakers, turn the Level control down all the way (counter-clockwise to Min). Make sure power is Off.
2 Rotate the Mode knobs to select a preset as appropriate (if you’re not sure, leave it at Normal). For more information, see
“Modes for Speaker Presets” on page 11.
3 Connect an XLR or 1/4-inch TRS cable from the output of your mixer or other device to the Input on the back of the first GSR
speaker. Make sure the Mic/Line button is set to the correct position on the first GSR speaker in each chain, depending on whether
you’re connecting a microphone (Mic) or line level source such as a mixer (Line).
4 Using an XLR cable, connect the Thru output on the first GSR to the Input on the next speaker. Make sure to set the Mic/Line
button to Line on this and any other GSR speakers in the chain.
5 Turn the speakers on using their Power switches.
6 Speak into the mic or raise the mixer output level while you slowly raise the speaker Level knob. Don’t point the microphone
into the front of the GSR speakers in order to avoid feedback.
7 If desired, press the HPF 75Hz button to engage the high-pass filter. This can eliminate any rumble or similar low-end noise that
might enter the signal. (We also recommend engaging the high-pass filter when the GSR speakers are being used as floor monitors.)
Guidelines
Maximum Number of GSR Speakers
Never daisy-chain more than three (3) total GSR speakers together per channel.
Stacking
If using the GSR18 sub, you can raise one GSR speaker above it using a speaker pole (not included). Do not stack other speakers
directly on the GSR18 sub, as vibrations may cause it to fall off.
6 GSR Speakers Guide
Connections for Stereo
(GSR12 and GSR10)
The GSR12 and GSR10 can be used in pairs for stereo sound reinforcement as shown in the following figure.

Figure 3. Connections for stereo operation
To connect a pair of GSR speakers for stereo operation:
1 On the back of both GSR speakers, turn the Level control down (counter-clockwise to Min). Make sure power is Off.
2 On the back panel of each speaker, do each of the following:
• Make sure the same Mode is selected (if you’re not sure, set both speakers to Normal). For more information, see “Modes for
Speaker Presets” on page 11.
• Make sure the Mic/Line button is set to Line.
• Make sure the HPF 75Hz button is in the out position (disengaged).
3 Connect an XLR or 1/4-inch TRS cable from the Left output of the mixer or other device to the Input on the back of the GSR
speaker you’ve set up for the left. Repeat for the other GSR speaker, making sure to source it from the Right output of the mixer
or other device.
4 Turn the speakers on using their Power switches.
5 To check levels, begin playback of audio through the mixer with its mains or master output set to its recommended position,
then slowly raise the Level knob on the back of the GSR speaker. Repeat for the other speaker.
Chapter 2: Setups 7
Using the GSR18 Sub
To add a GSR18 to your system:
„ Using XLR or TRS cables, connect the output of your mixer or other device to the Inputs on the back of the GSR18. If you’re
only using a mono feed from a mixer or similar source, connect it to the Left Input on the GSR18.
You can also use a GSR18 subwoofer in combination with a pair of GSR12 or GSR10 speakers to form a powerful, full-range system, as shown in the figure below.

Figure 4. Stereo setup using a GSR18 subwoofer
To connect a GSR18 and a pair of GSR speakers for stereo operation:
1 On the back of each speaker, turn the Level control down (counter-clockwise to Min). Make sure power is Off.
2 Connect two XLR or 1/4-inch TRS cables from the Left and Right outputs of the mixer or other device to the Left and Right Ste-
reo Inputs on the back of the GSR18.
3 Using XLR cables, connect the L/R Stereo Outputs on the back of the GSR18 to the Input input on the back of each GSR10 or
GSR12 (left to left, right to right).
4 On the GSR10 or GSR12 speakers, do the following:
• Make sure the Level knob is down (set to Min).
• Make sure the Mic/Line button is set to Line.
• Rotate the Mode knob to select a preset as appropriate (if you’re not sure, leave it at Normal). For more information, see
“Modes for Speaker Presets” on page 11.
• Make sure the HPF 75Hz button is “in” (HPF engaged) to keep bass from GSR10/GSR12 from overlapping with the GSR18.
5 Use the Power switch on the back of the GSR18 to power it on.
6 To check levels, begin playback of audio through the mixer with its Mains or master output set to its recommended position,
then slowly raise the Level knob on the back of the GSR18.
7 Raise the levels on the other speakers by setting their Level knobs to the desired position.
Using the Phase Switch on the GSR18
If the GSR18 Level knob is up high but you’re still not satisfied with the amount of low-end you’re hearing, try engaging the
Phase switch on the back of the GSR18. Inverting the signal in this way can help minimize frequency conflicts caused by room
acoustics, distance, or speaker placement.

5 HPF 75Hz
The HPF 75Hz button engages/disengages the high-pass filter
(HPF). When pressed (button is “in”), the GSR speaker engages
a 24 dB per octave high-pass filter to reduce or eliminate
low-end rumble being picked up by microphone inputs (or
any noise below 75Hz). When you’re also using a GSR18 sub,
we recommend engaging the HPF on all satellite GSR10 or
GSR12 speakers.
10 GSR Speakers Guide
The Mode knob lets you select among four different presets to
“tune” the GSR speaker and optimize its performance in different situations. For more information, see “Modes for
Speaker Presets” on page 11.
11 Power Switch
The Power switch turns the GSR speaker on/off.
12 AC Power and Fuse
This socket accepts a standard IEC power cable (one is included) for AC power to the speaker. The fuse protects the
speakers from damage due to power spikes and surges.
13 Pole Mount Stabilizing Screw
This secures the GSR10 or GSR12 to a pole, when mounting
the speaker on a stand.
Modes for Speaker Presets
GSR10 and GSR12 speakers provide a Mode selector on the
back panel that allows you to choose one of four speaker
modes.
GSR18
Front
Each mode, described below, is a “tuning” preset that optimizes the response of the GSR speakers for different situations.
The differences between modes can be subtle at lower volumes, but become more pronounced the louder the speaker is
used.
Normal
Normal mode is the default mode (factory set), and is the best
all-around “flat” setting. Use this mode for the best overall
sound for all types of material (voice as well as music).
Hi-Fi
In Hi-Fi mode, highs and lows are boosted slightly while mids
are cut by a few dB to heighten presence, even at low volume.
This mode is optimized for audio playback (such as from a CD
player).
GSR18 front
LF Driver
DJ
18-inch subwoofer (500W).
DJ mode emphasizes the low-end and tailors the mids and
highs for clarity and punch, even at moderate and high volume. This mode has been optimized for DJ live performance.
Front Grille
The perforated steel grille is to protect the 18-inch woofer. Do
not block or remove front grille.
Voice
Use Voice mode when you’ve connected a microphone directly to a GSR10 or GSR12 speaker. Voice mode is high-pass
filtered at 90 Hz, and gives a slight boost to the frequencies of
the human voice to maximize intelligibility, even at lower
volume levels. This mode is perfect for boardroom presentations or public address applications.
The GSR10 and GSR12 also provide a high-pass filter on
the Mic input. For more information, see “5 HPF 75Hz” on
page 10.
Pole Mount
The top of the GSR18 provides a mounting socket that accepts
a standard speaker pole (1 3/8-inch (36mm)). Use this mount
to secure a standard speaker pole (not included) in order to
mount a GSR10 or GSR12 on the sub.
Handles
Handles are provided on both sides of the GSR18. We recommend using two people when lifting or carrying the sub.
Feet
Don’t remove the feet or casters. Always place the GSR18
upright (not on its side).
Casters (Wheels)
The GSR18 is equipped with removable casters that are
mounted to the amplifier side of the subwoofer for easy
transportation.

1 Heat Sink
The aluminum amplifier panel doubles as a heat sink, which
dissipates heat generated by the GSR amplifier. Do not block
the heat sink, and make sure nothing comes in direct contact
with it while powered on.
The Phase switch lets you alter the polarity of the input signal.
When the Phase switch is in its default “out” setting, phase is
unaffected. When “in” the signal is adjusted 180°. Try enabling the Phase switch if the overall sound in the particular
room seems like it’s “collapsing” when turned up. This can
sometimes occur when a sub is positioned off to the side, behind a curtain, or in applications where the subwoofer is not
firing in the same direction as the full-range speakers.
9 Frequency
2 Power Indicator LED
The Power LED lights green when the GSR18 is powered on.
3 Signal Present Indicator LED
The Signal LED lights green to indicate when the GSR is receiving an input signal.
4 Peak Indicator LED
The Peak LED flashes red to indicate that the speaker has
clipped; lower the source, or turn the speaker down using its
Volume control.
The variable low-pass Frequency knob lets you dial in the ideal
frequency to crossover to your full-range “tops” such as the
GSR10 or GSR12, to maximize bass output. Since the GSR10
and GSR12 both have a 75 Hz high-pass button, the ideal frequency to crossover to the “tops” would be 75 Hz. However,
all listening environments, “tops” from other manufacturers,
and personal tastes are different. So, depending on the placement of the GSR18 and how much bass is desired, the Frequency knob (along with the Phase button) lets you optimize
the bass response for any room or application.
10 AC Power and Fuse
This socket accepts a standard IEC power cable (one is included) for AC power to the speaker. The fuse protects the
speakers from possible damage due to power spikes or surges.
If you ever need to replace the fuse, you can do so by removing
the fuse cover, taking out the old fuse and installing a new
one. Always replace the fuse with one of the same rating.
