The wall-mounted, stainless DS-PA3 3.5 Watt Audio Amplifier from RDL comes with two line inputs and an amplified output to drive a 4 or 8-ohms speaker. It features a balanced line level input that may be connected to unbalanced. The gain range will accommodate standard unbalanced levels as well as professional balanced levels. In addition, it also features a stereo mini-jack input on the front panel, which is designed to receive standard -10 dBV consumer level signals from sources such as, a computer or personal media player. The left and right audio signals received on the mini-jack are summed to mono and amplified. When a source is connected, the rear-panel input is switched off. The amplified output level is controlled by a front-panel volume control.

A recessed slide switch on the side of the chassis is set during installation, which determines the sensitivity of the balanced rear-panel input. Amplification is provided by a high-efficiency Class D power stage with audio filtering tailored for crisp, pleasant audio clarity. The high-efficiency Class D output stage produces negligible heat for all levels of expected voice or music modulation. It is designed so that it can be mounted in a wall box. The front panel of the amplifier does not include any illuminated indicators, which makes it ideally suited to installation in dark rooms or areas. Its wiring is connected through a rear-panel detachable terminal block. The module operation is from a 24 VDC ground-referenced power supply.

Q: 4. Can we give input to 1 GX3 power amplifier from another GX3 power amplifier?

A: There are no outputs on the GX3 other than speaker outputs which can not be connected to the input of another amplifier. The GX3 outputsare designed to connect only to speaker inputs

Q: 5. Can this be used to amplify a signal over a long speaker cable? I have a 5.1 system installed, but since the left front and left back speakers have longer wires, their signal is lower. My system allows me to boost the signal to these speakers, but it's not enough. I need more signal to these two speakers.

A: The RDL ST-PA6 is designed to connect from a line level device. It is not able to be used in line with speaker level input and output.

Q: 6. Does this amp has rca input?

A: Yes it does

Q: 7. how many speakers can I connect per channel?

A: The QSC GX3 features 2 physical speaker outputs designed for optimal operation at 8 ohms. The unit is able to operate safely with a 4 ohm load as well which will give you a higher wattage output per channel. You are able to connect multiple speakers to each channel in parallel, but should be careful not to exceed the wattage and impedance ratings listed by the manufacturer.

Q: 8. is this loud enough for busking?

A: Yes, the FLY 3 was designed as a portable practice amp for use at home or while traveling and it is loud enough for performing in front of a small group of people. The sealed cabinet helps to project the sound and also to maintain low end.

Q: 9. Im frm Philippines.. What is the right wattage/amperes of transformer be use to power this Gx3

A: You would need a step down transformer such as this BH #SEST1500UD.

Q: 10. hello it can be connected to a voltage 220?

A: The QSC GX3 operates at 120V AC. You will need to use a step-down transformer to use it with 220V AC such as the Sevenstar ST-500 Step Up/Step Down Transformer - 500W (B&H # SEST500UD) or Watson Voltage Converter - 500 Watt Max (B&H # WAVCGSD500).
