MSR400 MSR800W POWERED SPEAKER POWERED SUBWOOFER
POWER AMPLIFIER SOUND SYSTEM
T here are many advantages to using powered speakers – the most obvious being that you don’t have to drag separate power amplifiers around or find a convenient place to
install them. Fewer cables need connection as well. There are, also, real sonic advantages.
The performance of an amplifier/speaker system depends to a considerable degree on the
matching between the power amplifier and loudspeaker; a surprisingly complex relationship
that involves impedances, amplifier loading, reflected EMF, damping, and a variety of other
factors best left to the guys with the scientific calculators. Fortunately, these things are pretty
much standardized, so you can connect just about any speaker of the appropriate impedance
and power handling capacity to an amplifier and get decent results. But in a powered speaker
like the MSR400, or a powered subwoofer like the MSR800W, everything can be (and is)
matched to perfection for optimum performance. All you have to do is connect your line or
microphone-level source.
For a simple system, you can use just a pair of MSR400s and a small mixer (actually,
these models have microphone inputs as well as line inputs, with gain controls, so in
a pinch you can connect a microphone directly to the speaker). The MSR400 employs
bi-amplification for the best possible sound across the entire audio spectrum. But if
you want serious low end, we suggest that you pair each speaker with a MSR800W
subwoofer that features a 800 watts power amplifier driving a 15" woofer in a specially
designed bass-reflex enclosure that can deliver bass your audience will feel as well
as hear. A simple pole stand adaptor allows an MSR400 to be piggybacked on each
MSR800W for optimum positioning, phasing, and overall sound.
P Series POWER AMPLIFIER
the P Series power amplifiers have been
designed specifically to deliver big, clean power output that will take full
advantage of the quality and power handling capabilities of Yamaha speakers.
The amps are equipped with YS Processing (Yamaha Speaker Processing) to deliver
a signal that is optimally matched to those speakers as well. All
models feature both XLR and 1/4-inch TRS inputs, and Neutrik Speakon, phone plug, and five-way binding post outputs to make connections quick and easy. Other features
include Yamaha's exclusive EEEngine technology which delivers high performance with exceptional efficiency, sweepable high- and low- pass filters for optimizing output to
any loudspeakers, compact and durable 2U chassis, and variable speed cooling fans.

MSR100
POWERED SPEAKER
With the MSR100’s built-in three-channel line mixer and power amplifier, you can actually use it as an all-in-one PA system. The built-in mixer has independent gain controls on each of the three channels, as well as master level and master low and high EQ controls, a link out jack so you can connect to another MSR100, and a clip indicator. But the
MSR100 also makes a great 100-watt powered speaker for use with a small mixer. MSR100’s can be pole-mounted, wall-mounted, suspended, or stacked – anywhere you need them.
You can even lay them on their side for monitor service. The MSR100 is a serious contender in the sound category, too, with a top-performance 100-watt amplifier perfectly matched
to a two-way speaker system consisting of a custom 8" woofer and 1" titanium diaphragm compression driver feeding a 90˚ x 40˚ horn. A durable molded enclosure with integral
handle makes this one of the most portable, convenient speaker systems available

HS series speakers
POWERED MONITOR SPEAKER
W hen choosing reference monitors for mixing
and music production, what you really need is an honest reference for your mix
rather than sound that has been tweaked or colored to sound impressive at the
expense of accuracy. Unlike
speakers that have exaggerated bass and
treble that make a good first impression but can't be relied on for accuracy,
Yamaha
HS series reference monitors have been
painstakingly crafted by our studio monitor engineering team to deliver
exceptionally
flat, accurate response that you can trust.
The HS series speakers are true studio reference monitors in the tradition of
the
legendary Yamaha NS10M. Whether you’re mixing
for stereo or 5.1 surround, mixes that sound good on Yamaha HS series
reference monitors will translate accurately
to the widest possible range of reproduction systems ... which is
engineer-speak
that means they’ll sound good on anything.
And that is the ultimate goal of any reference monitor. We should also mention
that the HS-series monitors not only sound
great, they look great, too.

Club
V Loudspeakers S-Series & C-Series
if
you’re tired of breaking your back for
mediocre speaker performance, it’s time to look at the Yamaha Club V S-Series.
Although they easily
load into and out of your compact sedan, they also deliver power
and performance that makes them ideal for up to mid-sized sound
reinforcement systems. And in the world of the touring PA, there’s virtually
no way you can cart gear around without bumping into the occasional
immovable object, so you’ll appreciate the durable carpet covering – which
also protects the interior of your vehicle from the speakers. Heavy-gauge
steel grilles and steel protectors help protect your investment, too.
In the Club V S-Series the refinements of generation V are taken to
the next level, with larger enclosures for improved low-frequency
performance, improved drivers for higher power handling, redesigned crossovers, stronger grilles, and dual Speakon® and 1/4"
connectors.

SPX2000 PROFESSIONAL MULTI-EFFECT PROCESSOR
SPX2000PROFESSIONAL MULTI-EFFECT PROCESSOR
The SPX2000, while inheriting the standard interface and common programs from its predecessors, brings a new sound quality with the ”REV-X” reverbalgorithm and the 24 bit/96-kHz audio DSP.

Processing) switch do, anyway? Glad you asked: it rolls off unnecessary frequencies below around 40 Hz, which helps to protect your speakers, and at the same time boosts frequencies from 60 Hz through
150 Hz by about 3 or 4 dB which, as you rocket scientists already know, is a sound-pressure-level boost of about 1.5 times. And although this won’t give you the bone-shaking bass of a subwoofer, it will make your bass and drums sound really cool. If
you’re reinforcing rock, turn it on.
CONNECTING THE XP308i MIC AMPLIFIER
CONNECTING THE XP308i
There are several ways to interface the XP308i to support a variety of applications.
The XP308i feature balanced inputs and outputs, so connecting balanced and unbalanced signals is possible.

Class A Operating Mode
One device conducts for the whole of the
Each output device always either fully on or off – theoretically zero power dissipation.
One device conducts for the whole of the

Conduction angle =
360 °.
The Class A stage
must be biased at a
current greater than
the amplitude of the
signal current.
Class B Operating Mode
Two devices, each conducting for half

Conduction angle = 180 °.
Class AB Operating Mode
Two devices, each conducting for just over
half of the a.c. cycle.
Conduction angle > 180 ° but << 360 ° .
Class C Operating Mode
One device conducts a small portion of
the a.c. cycle.
Conduction angle << 180 °.
Class D Operating Mode
Each output device always either fully on or off – theoretically zero power dissipation.
Example: The built-in speaker in a PC is driven by a Class D type “on/off’ circuit.

POWER AMPLIFIER
•Common-emitter amplifiers and operational amplifiers
require high impedance loads.
•To drive low impedance loads, a power output stage is
required.
•Designs vary in complexity, linearity and efficiency.
•Power dissipation and thermal effects must be
considered.
Properties of Power Amplifier Stage
Low voltage gain (usually unity).
High current gain.
Low output impedance.
R High input impedance
Differences between power amplifier designs
Efficiency / Power dissipation.
Complexity / Cost.
Linearity / Distortion.
Power amplifier designs are usually classified according to their conduction angle.
Conduction Angle
The conduction angle gives the
proportion of an a.c. cycle which the output devices conduct for.
E.g.
On all the time Þ 360 °
On half the time Þ 180 °
