OHM’S LAW AND THE HOT SPOT
All unpowered HOT SPOTS have a 16 ohm impedance, and like
most professional-type speakers have two jacks which are wired in
parallel (meaning the signal can travel into one jack and out of the
other).Think of each speaker as a “load” added to the amplifier. The
greater the number of speakers, the heavier the load. Adding too
many speakers can overload the amplifier, causing it to overheat
and distort. If the amplifier begins to distort, or if it becomes hot to
the touch, disconnect any extra speakers. One easy way to
determine the load on the amplifier is to use Ohm’s law, which
“
states: “The total impedance of N speakers in parallel is equal to
the reciprocal of the sum of the reciprocals. In equation form:
Page 5
Page 3
This equation may be used to calculate the equivalent impedance
for additional speakers in two-speaker increments. Determine the
impedance of the first two speakers, substitute Z total for Z , and
include the next speaker. Repeat the process until all speakers
have been included. The result should be the same as with the first
method. A word of caution: polarity rules must be observed when
connecting multiple speakers. Polarity will not affect the Z, but can
affect the quality and volume of the sound. If you are having
problems with any of these applications use Galaxy Audio’s
CRICKET Polarity and Continuity Test Set to check the polarity of
your cables.
EXAMPLE 2:
As long as all of the speakers have the same impedance rating, the
equivalent impedance of the system is the rated impedance of one
speaker divided by the number of equivalent speakers.
Z=
Z x Z
12
Z + Z
12
Where Z1 is the impedance (or ohm rating) for the first speaker, Z2
for the second, and so on, for every speaker in the chain. This
equation calculates the total impedance of the speaker system,
which should NOT be lower than the minimum impedance rating of
the amplifier.
EXAMPLE 1:
For one pair of speakers use the short form of the equation: the
product of the two speakers divided by the sum of the two
speakers is equal to the total impedance or the equivalent
impedance of the speaker system.

SOUND REINFORCEMENT BASICS
Avoiding feedback
Feedback (the shriek sometimes emitted by PA systems) occurs
when the microphone (or pickup) and speaker are positioned too
close together for a given level of volume. Once feed back occurs,
it will continue until either the volume is decreased or the
microphone or speaker is moved. Gain is the degree to which the
volume may be turned up before feedback begins. In setting up a
sound system, the objective is to maximize gain.
Monitor Placement
HOT SPOT Monitors should be positioned within arm's
reach of the performer.
Monitors should be placed to the rear of the
microphone being used by the performer.
Avoiding Distortion
Distortion in a monitor system usually occurs when the amplifier is
being overdriven-nearing the limits of its power output capability.
Overdriving the amplifier may be corrected by reducing the bass
frequencies in the monitor mix (low notes use a lot of power).
Since the HOT SPOT NEOLITE driver will not reproduce tones
lower than 200 Hz, reduce the low frequencies if the speaker
begins to distort. Distortion may also originate with a bad signal
source.
NEO DRIVER
Introduced in 2004, the NEOLITE driver is a state of the art
controlled bandwidth speaker that is included in all products
covered in this manual with the exception of the MSPA. Tailored to
reproduce a frequency range from 150 Hz-18 kHz, the NEOLITE is
manufactured with the rare earth element Neodymium that has an
extremely intense magnetic field in comparison to its weight. This
magnetic field is also very concentrated, allowing the speaker to be
placed near sensitive equipment that may be affected by a strong
magnetic force, such as a TV or a computer monitor.
Page 8
HOT SPOT SERIES/MICRO SPOT VC
HSRG/HSVC The HOT SPOT was created as the solution to the
problem of musicians and public speakers not being able to hear
themselves while performing. The HOT SPOT's design is
unsurpassed in efficiently reproducing the crucial vocal range
frequencies from 150Hz to 18 kHz.
Each Hot Spot comes with a built in stand mount that allows the
unit to be placed on nearly any microphone stand, close to the
performer, for true near field vocal monitoring (some microphone
stands may require the optional stand adaptor SA-1)
The Hot Spot VC (HSVC) comes with a volume control that not
only affects the volume of the unit, but also the impedance of the
unit. (See chart [T.1] pg.7 for more information about the volume
control).
MSVC
Like the Hot Spot series, the Micro Spot VC is also tailored to the
vocal frequencies. The Micro Spot can be mounted to a
microphone stand using the included yoke bracket kit. For
information regarding the bracket kit see, MOUNTING YOUR
MICRO SPOT SERIES SPEAKERS. [A.1]( )
Like the Hot Spot VC, the Micro Spot VC is also equipped with a
volume control. (Please refer to table [ ] pg. 7 for information
regarding the positions on the volume control).

Using the PA5X140 as a...
Powered Monitor
When connected to a mixer’s monitor output or auxiliary output, the
PA5X140 enables each performer to create his/her own monitor mix.
Additional monitors can be attached to the PA5X140’s speaker output.
A recorder can be attached to the PA5X140’s LINE output.
Virtually any type of signal (instrument, mic level from a mixing
console, guitar, keyboard, tape player or condenser mic can be
plugged into the PA5X140 inputs.
Ultra-Compact PA System
The PA5X140 by itself is a one-piece PA system. Simply plug in a mic
or instrument for 100 watts of sound reinforcement power.
When two 16 ohm Galaxy Audio HOT SPOT personal monitors are
attached to the SPEAKER OUTPUT, the PA5X140’s power output
increases to 146 watts. Whether using the HOT SPOT or another
speaker, the PA5X140's power output depends on the impedance of
the speakers being powered. The load on the PA5X140's amplifier
section must greater than or equal to 4 ohms. Anything less will
overload the amplifier.
Practice Amp
A balanced signal from a microphone or second instrument may be
fed into one input while an instrument, CD player or tape deck is fed
into the other.

SPEAKER OUTPUT
1/4” connector output from the internal amplifier.
It can supply an external 8 ohm speaker with 73
watts of RMS power. This means two 16 ohm
HOT SPOTS can be connected to the system
without overloading the amplifier; great for a small
PA or monitor setup.
LINE OUT
RCA jack -10dB line level output
can be fed to a recorder, or to other
sound system components. It is
post-EQ, pre-compressor and
pre-amplifier.

POWERED MONITOR
The PA5X140's SPEAKER OUTPUT jack is designed to allow a
maximum of two HOT SPOTS to be “daisy-chained” to it.
The PA5X140 produces 146 watts when powering two HOT
SPOTS (see figure below)
Route cables:
1) From the microphone to Galaxy Audio’s PA5X140.
2) From the output of the PA5X140 to the first HOT SPOT.
3) From the first HOT SPOT to the second HOT SPOT.

STAND MOUNTING
All HOT SPOT's, both powered and un-powered, have a built in
microphone stand mount: just slide the microphone stand into the
receptacle on the bottom of the HOT SPOT. Some microphone
stands may require an adaptor (contact any Galaxy Audio dealer
and ask for an SA-1, microphone stand adaptor).

MOUNTING YOUR MICRO SPOT SERIES SPEAKERS
The Micro Spot VC comes equipped with a stand mount bracket kit.
Wall mount options are available for the Micro Spot VC from any
Galaxy Audio dealer, or online at
Stand Mounting
To install the yoke bracket, attach the SA-1 to the yoke bracket
using the included ¼-20 hex bolt and washer as shown in picture
below (A.1). Tighten using a 7/16 wrench or socket. The yoke
bracket assembly can now be screwed on to the microphone
stand. Remove the two plastic threaded inserts from the T-nuts in
each side of the Micro Spot with a small flat blade screwdriver.
Place the Micro Spot into position so that the wing screws at the
ends of the yoke line up with the T-nuts in the cabinet. Tighten the
wing screws by hand.
