Product outline
①Operating control switch button: Press the button for more than 1 second and then release it to turn the product on and off. If the Remote operation control switch(○
8)
is set to ON, this button will not work.
②Operating indicator LED lamp : It lights up during normal operation. It blinks when the product turns on and off or when there is a problem with the product.
③Right amplifier output connector: Match the + and - polarity and connect the right speaker with the speaker cables.
④Left amplifier output connector: Match the + and - polarity and connect the left speaker with the speaker cables (Be careful with the polarity, it is opposite to the right
speaker.).
⑤Balanced audio signal input connector : Connect to the balanced audio signal output connector of a DAC or Pre amp.
⑥Unbalanced audio signal input connector : Connect to the unbalanced audio signal output connector of a DAC or Pre amp.
⑦Option switch : When the product is in operating status, it may affect AM radio reception status. If this is the case, set to OFF position to improve AM radio reception.
When not in use, set to ON position.
⑧Remote operation control switch: Set to ON position when using the remote operation control function. Set to OFF position when not using the remote operation
control function.
⑨Remote operation signal input and output jacks: When Remote operation control switch(○
8) sets to ON, the product operation is controlled according to the state of
12v remote control voltage signal input(12v : on / 0v : 0ff ) through the 3.5mm input jack. The output jack outputs the remote control signal status of the input jack
for transmitting the remote control signal to the other remote product.
⑩Grounding terminal: This is the chassis ground(earth) terminal. If separate grounding is required, connect to the ground(earth) by ground(earth) cable.
⑪AC power inlet: Connect a C13 type AC power cable.
⑫AC power switch
Precautions
◼Before connecting the AC power, check the AC power voltage, and then connect an AC power cable.
◼Turn off the AC power switch before connecting or disconnecting any cables.
◼Balanced (○
5) and Unbalanced (○ 6) connectors cannot be used at the same time.
Product user guide
◼Connect the speakers and amplifier outputs connectors(○
3, ○ 4) by speaker cables. Be sure to match the + and - polarities when connecting the speaker cables.
◼Connect to the audio signal output connector from a DAC or Preamp to either the Balanced or Unbalanced input connector(○
5, ○ 6).
◼When using the remote operation control function, set the Remote operation control switch (○
8) to the ON position and connect the remote control signal cable to the
Remote operation signal input and output jacks (○
9)
◼Make sure that the AC power switch (○
12 ) is off and connect the AC power cable to the AC power inlet(○ 11 ).
◼Make sure that all connections are good, and then turn on the AC power switch (○
12 ).
◼When the power is on, the front LED lamp blinks several times and turns off.
◼Press the Operating control switch button (○
1) on the front panel for more than 1 second and then release the button to turn the product on. When using remote control
function, you can turn on the product by applying remote control signal (12v).
◼Play music through connected audio devices.
◼When not using the product, press the Operating control switch button (○
1) on the front panel for more than 0.5 second and then release the button to turn off the product.
When remote control function is used, you can turn off the product by not applying remote control signal (0v).
◼When the product is not in use for a long time, turn off the AC power by setting AC power switch (○
12 ) to OFF.
