Front Panel:
1. PROT- Protection indicator will light on in orange once the Amplifier comes into protection status. The protection maybe resulted from speaker line short circuit, speaker line open circuit, Amplifier overload and inner working temperature over 55?, this indicator give visually guidance ask for repair and It will light off once these failures been repaired. There are four separate protection indicators for each 4-Channel.
2. CLIP - Clip indicator will light on in red once the input or output is too high. There are four separate CLIP indicators for each 4-Channel.
3. INPUT - Input indicator will light on in green once there is any input signal has been detected. There are four separate input indicators for each 4-Channel.
4. OUPUT - Output indicator will light on in green once there is output signal has been passed. There are four separate output indicators for each 4-Channel.
5. POWER - Power indicator will be light on in blue once the unit has been powered whether by AC or DC.
6.POWER SWITCH - Power switch used to power on and power off the equipment.
Rear Panel:
1. AC POWER Socket - AC power cord for input from 110V to 230V, the power cord itself is auto-switching.
2. DC24V Battery Input - This input is used for battery power supply, which will be automatically switch on once the AC power supply fails as backup use.
3. 100V SPEAKER OUTPUT - The speaker outputs shall be connected to 100V line loudspeakers, the negative end to the speaker negative end and the positive end to the speaker positive end. There are 4-Channel separate 100V speaker outputs which could be managed respectively. These speaker output are supplied in phoenix connector.
Never mixed the negative end and the positive one, which may cause the short circuit protection. Never connection the low impedance loudspeaker to these 100V ends, which may burn up the speaker or have heavy distortion.
4. LINE INPUT - The line input support both balanced or unbalanced input, these input are supplied in phoenix connectors. There are 4-Channel separate line inputs which could be managed respectively.
5. 8? SPEAKER OUTPUT - The speaker outputs shall be connected to low impedance 8? loudspeakers, the negative end to the speaker negative end and the positive end to the speaker positive end. There are 4-Channel separate 8? speaker outputs which could be managed respectively. These speaker output are supplied in phoenix connector.
Never mixed the negative end and the positive one, which may cause the short circuit protection. Never connection the 100V line loudspeaker to these 8? ends, which may burn up the speaker or have heavy distortion.
6. Volume Control - The Volume control is used to adjustment the input volume.
HIGH PASS FILTER The high pass filter function will be enabled or disabled by pre-set the 4-Channel separate dipswitch. There are 4-Channel separate high pass filters which could be managed respectively.
7. AUTO-STANDBY - The Auto standby function will be enabled or disabled by pre-set the 4-Channel separate dipswitch. The enabled auto-standby function will automatically power come into standby once no input has been detected within 2 minutes. The Amplifier will immediately wake up once there is detection of input signal. There are 4-Channel separate auto-standby dipswitch which
