Congratulations on your purchase of a Sapphire III power amplifier with groundbreaking SSA technology.
The Sapphire Series with SSA technology is designed for years of reliable, flawless operation under rigorous
use. The implementation of advanced SSA technology dramatically reduces weight while increasing
output power, reliability, thermal efficiency and superior fidelity.
What makes SSA technology so advanced?The most recent evolution in audio amplification was the
invention of the Class-D topology. With the application of Class-D, amplifiers became smaller, louder and
more efficient. However, no one really improved fidelity--not until now. The first ever single-stage inverter
was born and its technology was patented in USA and worldwide. This single-stage inversion has
revolutionized the power inversion industry. Named as Class-SSA (Single Stage Switching Class A)
technology, this new topology delivers higher efficiency than Class-D and better audio fidelity
performance than all other amplifier topologies. SSA technology allows the amplifier to operate at very
low temperatures, and do not require massive heat sinks or bulky fans to cool the unit. The Sapphire Series
with SSA technology yields the highest audio quality and efficiency available.
For almost a century, power amplification was limited to Class-A, Class-AB and Class-D topologies. Now,
the industry is abuzz with a new ground-breaking technology that brings both power and potential while
accommodating the needs of the 21st century: Single Stage Class-SSA technology. Boasting
performance unmatched by its predecessors, Class-SSA stands out through features such as:
Sapphire III Power Amplifier

Digital Signal Processor (DSP)
Sapphire III is equipped with a high-quality DSP IC and hosts a comprehensive set of signal processing
functions to complement the amplifier in its intended application environment. These functions can be
controlled, edited, saved and recalled using the PC-based Control Panel application. Refer to the user
manual for the Control Panel for more specific information.
DSP Effects Implemented in Sapphire III include:
• Up to 170mS of system delay.
• Up to 10mS of high-resolution time/phase alignment delay.
• 5-band Parametric EQ with independent Frequency, Q control for each channel.
• Limiter with adjustable threshold and release times.
• 2-way crossover with frequency adjustment.
Sapphire III also allows control of Bridging (A/B, C/D), Input selection (Dante™or analog) and analog input
level via the Control Panel.
Effects Description and Control Parameters:
Time/Phase alignment Delay
The Time/Phase alignment delay function provides very short, fine-grained adjustments in the output delay,
mainly for aligning speaker phase in small spaces. The range is 0 to 10 mS, adjustable in 0.01mS increments.
System Delay
System delay provides much longer output delays, up to 180mS and is used for aligning speaker systems
that are placed far apart, such as towers in an outdoor concert setting or large indoor spaces. This delay
time can be adjusted in 0.1mS increments.
5-Band Parametric EQ
Sapphire III features 5 bands of parametric EQ. The default frequency bands are set at 100, 500, 1K, 2K and
4KHz. Each band has these functions:
• -10 dB to +10 dB attenuation.
• Q “Quality Factor” Adjustable from 0 to 14 for peaking specific frequencies.
• Per-band enable/disable.
Limiter
The Limiter, if enabled, controls the overall loudness of the output signal and can dampen peaks above
the set threshold. The Limiter block offers 3 parameters of control:
• RMS time constant from 1 to 128 dB/S.
• Decay from 1 to 128 dB/S.
• Threshold adjustable from 14 dB to +14 dB.
2-Way Crossover
A Linkwitz-Riley 2-way crossover is available if the user wishes to set up Sapphire III for a Bi-amped
configuration. This block sets up the amp to switch the audio between 2 outputs based on the signal
frequency. Corner frequencies can be set anywhere in the audio range from 10Hz - 20KHz. The gain for
each output can also be set between -10 dB and +10 dB.
Bridging
Sapphire III offers bridging to effectively double the power output at the expense of running as a 2-channel
amplifier in Bridged mode. Bridge mode can be selected from the Hardware switch on the rear of the unit
and Sapphire will follow this switch setting by default at power-up. In Bridge mode, Dante™channel 1 or
analog input A maps to the A/B outputs and Dante™channel 3 or analog input C is mapped to the C/D
outputs. Other audio inputs will be ignored.
In Bridge mode, the crossover is also available. In this configuration, the Sapphire III is effectively a mono
amplifier with bi-amped outputs. Audio must be input on Dante™ channel 1 or analog input A.
Input level control
Sapphire III defaults to the level settings on the front panel at power-up, these will control the level of the
signal at the ADC input. The Software Control Panel can override these settings if desired, for example in a
remotely-located amp setup where it is difficult or inconvenient to manually adjust the input level from the
front panel. Level is controllable from –∞to 0 dB.

Digital Signal Processor (DSP)
Input Selection
Sapphire III will accept audio input from either Dante™or the analog inputs on the unit. The input selection
controls which set of signals are routed to the DSP and amplifier outputs. This selection is for all 4 channels
at one time, they cannot be “mixed and matched.”
Dante™
Sapphire III features the Dante™Ethernet Connectivity from Audinate. This allows audio to be streamed to
(and from) the Sapphire III amplifier using standard off-the-shelf Ethernet cables and network hardware.
Sapphire III implements Dante™with 4-in/4-out audio and a control pipe to allow configuration of the DSP
and other features inside Sapphire III.
This manual is not intended to be a comprehensive introduction to Dante™, but rather will cover the steps
required to get Sapphire III up and running in a Dante™network. The user will require these items to
complete the Dante™ set-up:
• Sapphire III amplifier.
• A PC or Mac with hardware/software requirements to run the Audinate Dante™ applications.
• Dante™ Controller application.
• Dante™ Virtual Soundcard application.
• Cat-5 Ethernet cable and any other switch or other Ethernet hardware to connect a network.
Connecting to the Dante™ network
Sapphire III includes 2 Ethernet ports. Either port can be used to connect to the Dante™network. Two or
more Sapphire III units can be linked together in “Daisy-Chain” fashion no other configuration of the
Sapphire III is necessary.
Installing Dante™Virtual Soundcard (DVS)
DVS runs on a host PC as a licensed third-party application. The latest version of DVS can be purchased at
www.audinate.com and please follow instructions from Audinate to complete the install. More user
information and FAQs are available from the Audinate website.
Installing Dante™Controller
Dante™ Controller can be downloaded at www.audinate.com for free. Please follow the instructions on
the Audinate website to complete the installation, as well as for information on basic operation of the latest
software version and features, and user FAQs.
Using Dante™controller
When DVS is installed, Sapphire III can be connected to the PC via a network cable to complete the audio
link. Start Dante™Controller and within a short time, the host PC DVS driver will appear as a device on the
network, as will any Sapphire III amplifiers and other Dante™devices connected to the network. Use the
routing matrix in Dante™ Controller to connect the desired channels between DVS and Sapphire III.
The host PC can be used as a signal source to supply audio to the Sapphire III. Media players, DAWs and
PC-based mixing/DJ software can be used via DVS. Routing the DVS “Transmitter” outputs to the Sapphire
III “Receiver” inputs will complete the connection and allow audio to be streamed to the amplifier(s).
Note that Sapphire III reports audio OUTPUTS (Transmitters) as well as inputs in Dante™Controller. This allows
Sapphire III analog inputs to be used as a signal source on the Dante™network, and these can be routed
to other Sapphire III or Dante™devices. An example would be a small club where audio outputs from an
analog mixing console would be connected to a Sapphire III, and then the audio distributed to other
Sapphire III amplifiers within the venue to drive multiple sets of speakers in remote locations. Note that via
Dante™, multi-channel audio can be transmitted to remote amplifiers via Ethernet with no loss of audio
quality and very low latency.
