AD-7300PA+ 7 Channels AV Power Audio Amplifier

• 7 independent amplifier circuit modules, which are low distortion and high speed HI-FI, can offer full audio resolution. Note: FL, FR channels use external heatsink, their classA working current is higher than other channels.
  Before working, make sure the cables are correctly connected.

• Perfect amplifier protecting circuits (short protection, self-excitation protection, overheating protection and DC protection)

• 7 channels equipower output, meet different occasion needs.

• Big power switching power supply, abundant power stock.

• Big power tube parallel output, can supply 45A current output, big output power margin.

• High strength and durable casing structure; Scientific inner setting, strong anti-interference ability; High quality aluminum panel, simple and easy appearance.

Important precautions

Warning

• Avoid any dangers, please don’t open the cover (or rear panel).
• Please contact qualified worker if maintenances are needed.
• Avoid firing and electric shock, please don’t wet or damp the unit.

Features

This is a new audio amplifier combines with switching power supply and analog amplifier.
Power changes from traditional filter transformer to switching power, power output is greater and stronger; Amplifier uses our classic HI-FI circuit; 7 independent channels, each channel use high end gold plated RCA and XLR terminals, you can choose any one of them as music source to work with preamplifier. This is a popular high end amplifier which combines with HI-FI and AV, it will meet your different favors.

Front Panel

1. Standby button: press this button can turn on/off the unit. If unplug the power cord when the unit is on, it will return to the current status when you plug again the cord.
2. Standby indicator light: standby status, the indicator light is red; protection status, the light flash every two seconds.
3. DIM: this button can adjust brightness of indicator lights.
4. DIM indicator lights: only when background indicator lights are dim into off, this DIM indicator light will turn on color green.
5. DC ammeter: single indicate working status, it works when FL-FR-C have singles.

Rear panel

1. AC INPUT: power input terminal.
2. Protectors: 20AL250V, mains supply over current protection, any unusual situation it will protect the unit, press this button to normal power supply status.
3. Analog single input: input terminals that connect cables to preamplifier.
4. Signal channel switch: switch for balance and unbalance.
5. RCA input: input terminals that connect cables to preamplifier.
6. Amplifier signal output terminal: for connecting speaker cables, make sure positive pole and negative pole connections are correct.
7. Trigger input: level input port for preamp trigger on/off
8. Link input: level input port for preamp brightness control.
