The Audiophonics PGA2310 preamplifier is an extremely versatile device at a more than affordable price. If it is first presented as a preamplifier, it also offers volume control and input selector features, with additional Bluetooth 4.2 support.
2-channel preamplifier with volume control, three equalization bands and source selection 4 stereo inputs on RCA connector. Incorporates a double regulated linear power supply for each channel of the stereophonic signal.
This source selector greatly facilitates the management of your audio sources and eliminates the need to disconnect and reconnect devices before changing them. It has 3 possible inputs for one output, all on stereo RCA connectors.
The IPAR 1023A is a hybrid device headset amplifier / preamplifier / source selector that displays excellent audio characteristics including a high power level, two isolated circuits with independent control of volume. It is an ideal choice to mount a compact audio system or add features to an existing hi-fi system.
this passive attenuator uses a precision resistor that is connected in parallel with a 1% SMD mechanical resistance switch. this resistor is connected to the potentiometer, which, depending on its position, more or less connects the output to ground and thus varies the volume.
This switch is an inexpensive solution for connecting up to 4 audio / video devices to a television set, projector or sound system. A digital marking corresponding to the RCA inputs facilitates the identification of the source
