Operation Guide
How To Use
CA-1 Protection Function
This product has complete anti-impact function, including delayed protection on power on, shut off protection, which can
ensure no abnormal impulse current output.
CA-1 Operating Process
1. Check the connections between this product and related devices before power on.
2. Power on the product by press the power button, after the connections are confirmed to be connected well. The sleep
indicator will be lighted to indicate the preamplifier enter into sleep state.
3. Start the preamplifier by press sleep button by hand or F1 button on remote controller. The product will be shifted
between work state and sleep state automatically after each press. The sleep indicator will be dead after the pre-amplifier
enter into work state. The pre-amplifier will enter into the count down period for 60s while the sleep indicator is off and
the warm-up indicator is light. During this warm-up stage, except press the sleep button or F1 button, all other operation
are invalid. After the count down period for delay, the pre-amplifier will be automatically interconnected with the signal
input channel which is recorded in memory and keep the volume value in memory when shut off last time.
The volume will be automatically adjusted to volume 30 if it is over volume 75 before last time shut off.
4. After warm up, you can implement all controls by hand or remote controller. You can select the input channel, and set
the sound source in play mode, turn on the volume level slowly. Then, you can enjoy the music.
5. When shut off the audio system, please power off the power-amplifier at first, and then power off this preamplifier itself.
Caution: Must cut off the power for non-play for long-time.
PA-1 Protection Function:
This product has complete anti-impact function, including delayed protection on power on, shut off protection, which can
ensure no abnormal impulse current output.
PA-1 Processing:
1. Ensure the connections between this power amplifier and relevant devices are correct before power on;
2 Power on only if the cables are confirmed to be connected well, the indicator glitters to indicate the machine enters into
the warm up status. After about 8 seconds, the power amplifier enters into working state, then you can play the music.
3. When shut off the audio system, please power off the power amplifier at first, and then power off the preamplifier.

How To Use
In order to help user operate this amplifier more convenient, following is some frequently asked questions during the
operation. If you want more information, please visit our web site www.xindak.com or send e-mail to [e-mail].

PA-1 FQA
Q.Why operate on the input selector on panel or select switch and volume control button on remote control, there is
no response from amplifier?
A. The reason for that may because: 1. The amplifier is in preparation stage after power on. Please wait. 2. The
amplifier is in mute model, and the Mute mark glitters as 1Hz frequency. Please release the mute;
Q. why the attached remote control can not work?
A. This problem may because: 1. there is no batteries, please take out the batteries attached, open the rear cover of
the remote control by screwdriver and install them according the exploitation on the chapter “Operation and
maintenance for remote control”. 2. The batteries is spent, please replace the batteries. 3. There is barrier between
the IR sensor and infrared emitter. 4. The remote control has been out of the max available operation distance.
Q. Why there is no sound output after power on?
A. That may because: 1. The amplifier has not been connected to sound source or there is no output from sound
source. 2. The amplifier has not been connected to loudspeakers. 3. The signal indication is different with the input
signal, please select the correct signal channel. 4. The volume knob is set at the 0, please set the volume in proper
level.
Q. How to replace the fuse?
A. If the fuse melts, please pull out the power cord at first, then open the fuse socket on the power input socket. After
