2 X-DA1500/DA2250/DA4125/DA4060 Operations
Guide
The DA amplifies audio signal power it receives from audio input devices to maintain clarity and
volume when broadcast over many speakers.
The High Efficiency Power Amplifier is referred to as "DA" throughout the remainder of this manual.
There are models of amplifies:

X-DA1500

X-DA2250

X-DA4125

X-DA4060
This chapter introduces how to operate the power switch of X-DA and the precautions during
operation.

Power Switch On/Off

The system powers on when the power switch is in the "I" position, and powers off when the switch
is in the "O" position.
When the indicator light for the main or standby power supply on the front panel of the DA turns
green, the respective power supply is working normally.
When the power supply indicator light turns orange, the respective power supply has experienced
a fault. Check whether the power supply is connected correctly and that the DA power switch is
turned on.

Precautions

Do not operate directly on DA. Relevant operation can be conducted through outside control
devices.
When using the DA, pay particular attention to the following issues.
Notice:
Make sure all cables are connected properly before turning on the DA.
Pay particular attention to which audio input source is selected and configure the output signal
level appropriately, as this can save electricity.
Do not connect the grounding output cable with the grounding input cable as this causes a short
circuit to occur.
Warning!
Do not alter the circuit board or schematic diagram.
When the CLIP indicator light is flashing red, immediately reduce the audio volume. If peak clipping
occurs for too long, the DA could be damaged.
If the audio signal or peak clipping signal is too high, the speakers could be damaged.
