06 故障保护
SGP1的设计可以检测过载、短路、温度过高和交流输入电压过低等故障。
当潜在的破坏性故障发生时，放大器进入“保护”模式，以防止对放大器或扬声器
的损坏。如果故障触发了“保护”模式，请关闭SGP1。在重新开机之前，请排查
机器，确认故障原因并纠正。
1 故障显示
电源灯亮，一个通道或者两个输出通道亮红灯
（注意：只有交流AC存在时，此故障显示才会持续。在完全失去交流电源
的情况下，这个错误显示将保持约30秒，然后所有的灯将关闭。）
2 典型原因
交流电可能欠压
喇叭的负载阻抗可能太低
散热器散热通道被阻塞
功放在高输入的测试条件下过载
3 解决方案
检查交流电源
确保标称立体声负载阻抗为3Ω或更高
保持散热片周围足够的空间
预留时间让功放冷却
关掉音源
重启SGP1

The Power of Original Sound
SGP1

The SGP1 is a Class AB Reference-Grade Audio Power Amplifier that is
designed specifically for High Resolution Audio(HRA) recording and playback
system. The SNR and THD extraordinary performance of the SGP1 pushes the
performance of fully discrete Class AB amplifiers to a whole new level.
SGP1 has been developed and designed by SONCOZ Team for nearly 3 years,
and finally achieved mass production. Please take a few moments to familiarize
yourself with its operation.

03 OPERATIONS AND STATUS INDICATORS
1 Turn On/Off the Power
Turn down the audio source before turning the unit on for the first time
Press the PWR button to turn the unit on or off
In the event of a total loss of AC power, all lights will slowly turn off within
30 seconds
02 QUICK START GUIDE
1 Connect all cables before turning the unit on
2 Ensure the Speaker Binding Posts(OUT R+/R-/L+/L-)do not short circuit or
connect to ground
3 Check your local voltage level switches before turning the unit on
4 Turn down the audio source before turning the unit on for the first time
5 SGP1 is a pure power amplifier, which requires the audio source component
to have Pre-Amp function
6 In order to avoid damaging the speaker, make sure that the Pre-Amp volume
is low when you start it up for the first time
7 When you need to replace or disconnect a cable, please turn off SGP1 first
8 Please turn off SGP1 by press the power button first, then pull out the power
cable or cut the main power
2 PWR: Power Status Indicator
Orange LED light is Off = Power is Off
Orange LED light is On = Power is On = Normal operation 07

3 OUT L/R: Over-Heating Protection Indicator

1 Fault Display
PWR light is on, one or both OUT Red lights on (Note: This fault display
will only persist if AC is present. In the event of a total loss of AC power,
this error display will stay on for about 30 seconds and then all lights will
turn off. )
2 Typical Causes
The AC line voltage may have dropped below allowable limits for a few
seconds
The load Impedance of the speakers may be too low
Heat sinks may be obstructed
Amplifier has been overloaded with a high-amplitude test tone
3 Required Actions
Check the AC power source
Make sure the nominal STEREO load impedance is 3 Ohms or higher
Maintain adequate clearance around heat sinks
Allow time for the amplifier to cool
Turn down the audio source
Restart the SGP1

06 FAULT PROTECTION
The SGP1 is designed to detect Overloads, Short Circuits, Excessive
Temperatures, and Low AC Input Voltages. When a potentially-damaging fault
occurs, the SGP1 enters a "PROTECT" mode to protect against damage to the
amplifier or speakers. If a fault has triggered the "PROTECT" mode, please turn
off the SGP1. Identify and correct the cause of the fault before restarting it.
