Advantages of the Sapphire Series with SSA technology :
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.

Getting Started
Important!
1. Make sure amplifier’s output connectors are plugged into speakers
only using a speaker cable.
2. Before making connections to amplifier or reconfiguring the routing
of amplifier, turn down amplifier’s control levels and switch off
amplifier.
3. Before shutting down the audio system, turn off the amplifier first.
While powering up your audio system, turn on the amplifier last.
4. Save the shipping box, warranty card and packing materials.
Settings:
1. Make sure the power switch of amplifier is turned off.
2. Turn down all the level controls.
3. Determine which amplifier mode is used for the application：
A. Stereo Mode: Input A signal is routed to output channel A,
Input B signal is routed to output channel B.
B. Bridge Mode (only for Sapphire II): Combines two channels
and doubles the output power.
Input A is used for bridged output channels A and B. Input C is used for
bridged output channels C and D. When in Bridge Mode, Input B and
Input D are not connected. 8-ohm is the minimum speaker impedance
connecting to amplifier in Bridge Mode.
4. Set the amplifier mode switch to the application.
5. Refer to the wiring diagram for the speaker connection. There are
specific speaker Speakon connectors for Bridge Mode.
6. Connect the amplifier output to the speaker using correct speaker
cable.

Connections:
1. Be sure to switch off the power of the related equipment before
making any connections.
2. Balancing cables are used to connect the mixer console (or the
other signal sources) “MAIN OUTPUTS” to the amplifier’s “INPUTS”.
3. In STEREO mode:
A. Input stage: connect the cables from the signal sources to the
Amplifier’s INPUT Jacks, XLR.
The balanced XLR inputs are wired as follows:
1. Pin 1 = shield (ground)
2. Pin 2 = hot (or +ve)
3. Pin 3 = cold (or -ve)
B. Output stage: connect speaker cables to the OUTPUTS---Speakon
connectors.
The Speakon connectors are wired as follows:
1+ = hot (+ speaker terminal)
1- = cold (- speaker terminal)
4. In BRIDGE mode (only for Sapphire II):
A. Input stage: connect two cables from signal source to Input A and
Input C, Input B and Input D are not connected.
B. Output stage: connect the speaker cables to the OUTPUTS by the
bridged Speakon connector.
The bridged Speakon connectors are wired as follows:
1+ = hot (+ speaker terminal)
2+ = cold (- speaker terminal)
5. Plug all the sound system’s power cord into suitable AC outlets,
properly grounded and with adequate current supply.
6. Make sure the signal source is power up to deliver the right signal
amplitude to the amplifier.
Always turn off and
disconnect the amplifier
from mains voltage
before making audio
connections. Also, as an
extra precaution, turn
down the attenuators
during power-up.

7. Turn on the power switch of amplifier. Verify that the POWER LED
lights.
8. Turn up both level controls slowly on the amplifier (Stereo Mode).
Then, music is heard and signal LEDs in blue color.
If the signal LEDs are flashing in red color, turn down either the level
controls on the amplifier or the sourcing signal’s output level controls,
until the signal LEDs are no longer flashing and returned back to blue
color .
9. For better listening, it is recommended to adjust the amplifier level
controls rather than the sources signal output level.

the amplifiers plugged into it. The outlet
should be a three-prong socket that
matches the power cord.
Unplug the amplifier’s power
cord from the outlet when the
amplifier will be left unused for
a long period of time.
Level Controls:
Adjust the input level. To increase signal gain,
rotate the knobs clockwise. To reduce the gain,
rotate the knobs counter- clockwise.
ON/OFF(Standby) Button:
The amplifier is on when the button is pressed in.
When the button is pushed out, the amplifier is off
(standby). 8Speakon Outputs:
Connect the amplifier to the speaker using
professional cables with twist-locking plugs.
9XLR Inputs:
Route line-level input signals into these
combination jacks using XLR, balanced
1/4” TRS.
Power On & Standby LED:
When the ON/OFF button is pressed in (power on),
the LED will light in blue. The LED will light in red,
when the ON/OFF button is pushed out (standby).
6Rocker Switch:
Use this rocker switch to turn the unit on or
off. This connects/disconnects the AC
power to the AC power transformer. The
amplifier is on when the top of the switch is
pressed in. It is off when the bottom of the
switch is pressed in.
