Welcome
Congratulations on your purchase of a Sapphire power amplifier with groundbreaking SSA technology. Our passion is to
make a difference by offering innovative power amplification technology for the music industry. All the products
featuring our proprietary SSA technology deliver a new statement for maximum sound quality. The implementation of
advanced SSA technology dramatically reduces weight and size while increasing output power, reliability, thermal
efficiency and sonic 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,
the sonic quality needs to be improved—not until now. The first ever single-stage inverter was born and its technology
was patented in USA and worldwide. This single-stage power conversion has revolutionized the power conversion
industry. Named as Class-SSA technology (Single Stage Switching Class A) , 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 does not require massive heat sinks or bulky fans to cool the unit.
Products with SSA technology yield the highest audio resolution and efficiency available.
Boasting performance unmatched by Class-A, Class-AB and Class-D topologies, Class-SSA stands out through
features such as:
• A single stage power conversion instead of the traditional DC-DC power supply, rectifier, filtering and
amplifier stages.
• Zero crossover distortion.
• System isolation via a high frequency transformer.
• True bidirectional energy flow which allows inductance load energy return to primary power supply.
• ZVS, ZCS soft switching — to maximize the system efficiency.
• Over 90% ultra-high system efficiency during DC-AC power conversion.

Sapphire III Base Digital Signal Processor (DSP)
In order to provide users with comprehensive ability to process signals in different environments, Sapphire III Base is
equipped with high quality digital signal processor. Functions can be controlled, edited, saved and called through PC
application. For more specific information, please refer to the user manual for the application.
Effects that the Digital Signal Processor in Sapphire III Base can be implemented:
• 85 milliseconds of system delay.
• 10 milliseconds of high-resolution time/phase calibration delay.
• Isolated EQ in 5 frequency bands which control Q value in each channel independently.
• Limiter with adjustable threshold and release time.
• Frequency adjustment of two-way frequency divider.
The Sapphire III Base supports Bridge Mode (A/B, C/D) and also supports Dante™Audio/Analog Audio input whose
volume can be controlled via User Interface.
�
Control Parameters and control effects of DSP in Sapphire III Base power amplifier:
�
Time/phase calibration delay
The time/phase calibration delay function provides output delay with short-time fine adjustment. It is mainly used for
phase adjustment of speakers in narrow space. The adjustment range is 0 ~ 10 millisecond with 0.01 millisecond
increment.
�
System Delay
System delay can provide longer output delay up to 85 millisecond. It is used for the adjustment of long-distance
speaker systems such as outdoor concert or larger indoor space. Delay time can be adjusted with 0.1 millisecond
increment.
�
5-frequency-band parameters equalizer (EQ)
Sapphire III Base has a 5-frequency-band parametric equalizer. The default frequency bands are set as 100, 500, 1k, 2k
and 4k Hertz. Each frequency band has following functions:
• -15dB to +15dB attenuation.
• “Quality factor” (Q value) peak regulation of specific frequency from 0 ~ 16.
• Each frequency band has enable/disable function.
�
Limiter
If the limiter is enabled, the total volume of output signal can be controlled and the peaks that higher than the setting
threshold can be inhibited. The Limiter offers 3 control parameters:
• RMS time constant from 1 ~ 100 dB/s.
• Attenuation from 5 ~ 23 dB/s.
• Threshold adjustment from -24 ~ +24 dB.
�
Two-way Crossover
The audio stream is input through Dante™channel 1 or analog input channel A. At the output of the crossover,
channel A will output the low frequency signals while channel B will output high frequency;
The audio stream is input through Dante™channel 3 or analog input channel C. At the output of the crossover,
channel C will output the low frequency signals while channel D will output high frequency;
Gain of each output can be set among the range -10dB ~ +10dB.
�
Bridge Mode
In Bridge Mode, Sapphire III Base is used as a two-channel power amplifier which doubles the power output. Bridge
Mode can be switched from a hardware switch located at the rear panel of the power amplifier. Sapphire III Base will
follow the switch settings when starting up. In Bridge Mode, Dante™channel 1 or analog input channel A will be
mapped to channel A/B, while Dante™channel 3 or analog input channel C will be mapped to channel C/D. Other
audio input will be ignored.
�
A2-way crossover is available in Bridge Mode. In this configuration, Sapphire III Base can be considered as a
two-channel power amplifier. In this mode, channel A/B will output the low frequency signals while channel C/D will
output high frequency.

Sapphire III
（Base）Power Amplifier

Sapphire III Base Digital Signal Processor (DSP)
Input volume control
Sapphire III Base accepts the volume from the front panel knob settings as the default volume setting when starting up.
These settings will control the input volume of the ADC. The software control panel can override these settings. For
example, when it is difficult or inconvenient to adjust the volume knob of a remote power amplifier manually, the
volume can be set by software user interface to adjust the volume in a range of –∞to 0 dB. In practical applications,
volume knobs are generally set to the maximum setting and controlled remotely via the UI.
�
Input selection
Sapphire III Base can accept any of the audio streams from Dante™network or other analog audio inputs. Input
selection will determine which signal will be sent to DSP and output. Input selection operates on 4 channels
simultaneously, so it cannot be “Mixed and Matched”. The default input is the analog audio stream input in the factory
configuration.
Dante™ Network
Sapphire III Base features the Dante™Ethernet protocol. Sapphire III Base can input/output audio signals base on
existing standard Cat-5 shielded twisted pair and other network hardware. Sapphire III Base implements 4-in/4-out and
also the control of DSP or other configuration through Dante™ network.
This manual will not fully introduce Dante™, but only cover the steps that needed to start and operate Sapphire III
(Base) in Dante™ network. Dante™ network can be set base on following information:
• A Sapphire III (Base).
• A PC or Mac that can meet the software/hardware environment requirements.
• The Dante™ controller application.
• The Dante™ Virtual Sound card application.
• Cat-5/6 cable and switch or other hardware connected to the desired network.
Connect to the Dante™ network
Sapphire III (Base) has 2 Ethernet ports which are connectable to Dante™network. For systems contain more than 1
Sapphire III (Base) units, other configurations are unnecessary for “Daisy Chain” connection.
Install Dante™virtual sound (DVS) card
Dante™ Virtual Sound card is an authorized third party application running on PC. The latest version of DVS can be
purchased at www.audinate.com. Please follow the instructions to complete installation. For further information about
FAQs and basic operations please check the Audinate website.
Install Dante™Controller
Dante controller can be downloaded from www.audinate.com for free. Please follow the instructions to complete
installation. For further information about the software, FAQs and basic operations please check the website.
To use Dante™controller
After the DVS card is completely installed, Sapphire III （Base）can connect to PC through Cat-5 shielded twisted pair.
A moment after Dante™controller is started, the virtual sound card driver in PC will be displayed as a device on the
network. To connect Sapphire III (Base) and other Dante™devices to network, Dante™controller is used for channel
connections between DVS and Sapphire III (Base).
PC can provide Sapphire III (Base) with audio signal via DVS and can support streaming of audio from Media Players,
Digital Audio Workstations and Mixer/DJ software. A connection can be considered as complete when the output of
“Transmitter” through routing virtual sound card connects to the input of “Receiver” in Sapphire III Base, and a green
check mark is seen at the intersection of the connection matrix.
Please note: The analog audio input of Sapphire III (Base) can also be used as a signal source on Dante™Network, and
can be routed to another Sapphire III (Base) or Dante™devices. Thus, the analog input of Sapphire III (Base) can be
used as a signal source of Dante™network, and can be routed to other Sapphire III (Base) or Dante™devices. For
example: in a small club, mixer outputs an audio signal to a Sapphire III (Base) power amplifier, then assigns the audio
signal to Sapphire III (Base) in other places to drive multiple remote speakers. It is important to note that multi-channel
audio stream can be remote transmitted through the Dante™ network with low delay and no loss of audio quality.

STEREO/BRIDGE mode
STEREO/BRIDGE mode can be selected through the switch on the rear panel or through the UI.
For Stereo mode connection (figure 1):
• Signal input from CH A, CH B, CH C, CH D and output from corresponding channel A, B, C, D.
For Bridge mode connection (figure 2):
• “Bridge A B”: Signal is sourced from CH A and output from channel A with doubled power,
channel B is disconnected.
• “Bridge C D”: Signal is sourced from CH C and output from channel C with doubled power,
channel D is disconnected.
This chapter is about the configuration of a set of power amplifiers using the Dante™network. Not only independent
connections can be set up, but also multiple power amplifiers can be connected as “Daisy Chain”. Sapphire III (Base)
connects to the network hardware devices using Cat-5 cable. Sapphire III (Base) implements 4-in, 4-out audio signals,
Digital Signal Processing and other configuration.
Audio signal inputs
Audio signals can be input from Dante™ audio input or analog audio input:
• If “Dante™ Audio” is chosen, PC/Network switch is used to input audio signals and control the amplifier remotely.
Ethernet ports ETH1/ETH2 can input/output signals simultaneously, as Dante™ is bidirectional.
• If “Analog Audio” is chosen, XLR is used as the input source. A PC can only control the internal functions via the UI.
As the images show below, a single power amplifier is used as an example:
• If “Dante™ Audio” is chosen, PC/Network switch is used to input audio signals and control the internal functions.
There is signal from the analog input.
• If “Analog Audio” is chosen, XLR is used to input audio signals. PC can control internal functions via the UI.

Setting up a multi power amplifiers system using “Daisy Chain” :
An amplifier system which contains multi Sapphire III (Base) power amplifiers can be configured as the figure shown
below. Analog signals are sourced from a mixer or other audio source through the XLR inputs, while digital signals are
input from a PC/Network switch through Ethernet port (ETH1/ETH2). Cat-5 cables are used for the connection between
Sapphire III (Base) power amplifiers. Signals are output from ETH1/ETH2 ports to the speakers that connected to
Sapphire III (Base) end to complete a simple Daisy Chain connection system. Signals are transmitted within the system
via Dante™. Users can easily remote control the whole system through the PC User Interface including DSP.
