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.
Each mode, described below, is a “tuning” preset that opti-
mizes the response of the GSR speakers for different situations.
The differences between modes can be subtle at lower vol-
umes, 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).
DJ
DJ mode emphasizes the low-end and tailors the mids and
highs for clarity and punch, even at moderate and high vol-
ume. This mode has been optimized for DJ live performance.
Voice
Use Voice mode when you’ve connected a microphone di-
rectly 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 presenta-
tions or public address applications.
GSR18
Front
LF Driver
18-inch subwoofer (500W).
Front Grille
The perforated steel grille is to protect the 18-inch woofer. Do
not block or remove front grille.
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 recom-
mend 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.
The GSR10 and GSR12 also provide a high-pass filter on
the Mic input. For more information, see “5 HPF 75Hz” on
page 10.
