Getting Started
Important !
1. Make sure amplifier's output connectors are plugged into speakers only using a speaker cable.
2. Before making connections to the 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,
B.
Bridge Mode: 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 of the amplifier in Bridge Mode *.
4. Set the amplifier mode switch to the application.
5. Refer to (Connections "Analog output connection") for the speaker connection. Connect the amplifier output to
the speaker using correct speaker cable.
Power amplifier connections:
1. Be sure to switch off the power of the related equipment before making any connections.
2. Balanced cables are used to connect a mixer console (or the other signal sources) "MAIN OUTPUTS" to the
amplifier's "INPUTS". Please refer to (Connections "Analog input connection").
3. Connect speakers with the output end of the power amplifier.
4. Connect the power amplifier to a PC or network switch with Cat-5 shielded twisted pair. The Sapphire III (Base) User
Interface on the PC can control the amplifier remotely. For further information, please refer to (Sapphire III (Base)
User Interface introductions). Information about installation and operation of software, please refer to the
instruction of the relevant software.
5. Setting up the system of power amplifier, please refer to (Setting Up System) section.
6. Plug all the sound system's power cord into suitable AC outlets, properly grounded and with adequate current
supply.
7. Make sure the signal source is power up to deliver the right signal amplitude to the amplifier.
8. Turn on the power switch of amplifier. Verify that the POWER LED lights.
9. Turn up both level controls slowly on the amplifier (Stereo Mode). Then, music is heard and the signal LEDs light 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 .
