- Local StorageBuilt-in 4 GB EMMC (Audio file storage is 1 GB.)
- Audio InMIC 1~4: -28 dBV, 4.7 kΩ, unbalance, 6.35 mm jack RCA in 1~4: 0 dBV, 4.7 kΩ, unbalance, RCA pin jack USB 2.0 × 1 Bluetooth Note: The 6.35 mm jack cannot be wired without connecting a microphone.
- Audio OutConstant voltage output × 2: 100 V COM & 70 V COM. When both channels operate simultaneously, each channel supports a maximum output power of 250 W; or channel 1 outputs 500 W independently while channel 2 remains inactive. Alternatively, constant impedance output × 2: 4 Ω COM & 8 Ω COM, with a maximum output of 250 W per channel. RCA out 1-2: 0 dBV, unbalance, RCA pin jack 3.5 mm out 1-2: 0 dBV, unbalance, 3.5 mm jack Note: Ensure that both the channel mode in the WEB interface and switch on the rear panel are set to the corresponding mode (100V/70V or 8Ω/4Ω).
- LED IndicatorPower Indicator (solid white): the device is normal working. USB flash drive indicator (solid white): the device is in USB flash drive mode. Bluetooth Indicator (solid blue): the device is in Bluetooth mode EVAC Alarm Indicator (solid red): the EVAC alarm has been triggered. MIC1 Indicator (solid white): the MIC1 audio input is connected normally. Module Indicator: FLT solid indicates overload or other system faults; CLIP solid indicates clipping or other exceptions; SIG solid indicates normal working.
