1. Safety Precautions
Carefully read the user manual before operation.
1. Check carefully all buttons are positioned correctly before startup.
1) Emergency Stop button in correct position in pressed state.
2) ON/OFF in OFF state.
2. Main supply capacity should meet the requirement; otherwise it will affect output power of
amplifier during high current output.
3. Handle the amplifier with great care and follow the symbols on the package: fragile, handle
with care, top (an arrow pointing up), keep dry and protect from shaking.
4. Never operate live signal and load wires with voltage or current output to protect the safety of
equipment and personnel.
5. In case the power outlet for powering up the amplifier does not have protective ground
customer must connect the ground socket to the protective ground at the test site.
6. The voltage output of over 36V is considered as dangerous and care must be taken.
7. Please close and lock the back door when the wiring connection is confirmed correctly.

5.4 PA Output Interface
Important Note: WhenThis Device is used in the PAV5000 cabinet, K0and K1 need
to be switched ON for Normal Amplifier Output Use without resistive load connected
both for AC and DC output mode.
In AC output mode:
K0 could be switched OFF for cutting off the amplifier output.
In DC output mode: K0 need to be switched ON always.
Could Not be switched off for cutting off the amplifier output. User need to directly
operate the amplifier unit to cut off the output. K0 is forbidden to use.
