Product description:1. If you have a line level signal source (TV audio, MP3 player, video game machine, cell phone, tablet, computer, record player, etc.) to output to other devices at the same time (such as power amplifier and speakers or headphones), this product can solve the problem of one set of stereo input, which can allocate four sets of stereo, output independent four sets of volume adjustment function, with each channel output band + 20dB gain.2. For a powerful signal amplifier distributor, you may need to run several long lines between the TV audio line and a receiver on the other side of the room, providing high gain through any line level signal source, allowing longer cable lines to run, or requiring "buffering" to solve low volume problem. You can use it to add signal amplifiers between the line level signal source and the power amplifier, and the RCA jack matches almost all other product interfaces.3. This product can increase the sound quality of the control signal and reduce the bottom noise. With a large dynamic range, it will not produce a burst. The output volume is controlled by sensitivity adjustment knob, and DC 12V power supply is adopted to ensure full thrust.Product parameters:1. Input impedance: 100K Ohm2. Input level: +14 dBV3.

About The Product1. 6 port stereo speaker selector amplifier switch switcher 2. The speaker switcher allows the user to connect multiple pairs of speakers to a single stereo receiver or amplifier or vice versa to multiple amplifiers/receivers of a single speaker pair. 3. The device has a convenient button terminal that can accept up to 12 AWG speaker lines. 4. Note: this speaker switch does not allow multiple speaker pairs to be selected simultaneously. Only one pair of outputs can be selected at a time. 5. This speaker selection can also be used in the opposite way, imagine having multiple amplifiers connected to a speaker pair for setting. Because each stereo amplifier has its own sound characteristics, the user can connect different power amplifiers to the switch and then output to the same speaker pair. 6. Connect multiple speakers to an audio amplifier/receiver as loudspeakers to select a pair of speakers at a time. 7. Connect multiple amplifiers/receivers to a pair of speakers as an amplifier selection to select one amplifier/receiver. 8. The high-current amplifier protection circuit allows up to 6 pairs of speakers to be connected without damaging the amplifier. The protection circuit can safely protect unselected amplifiers or loudspeakers. 9. Select each time with a manual button on the front panel. Independent left/right channel grounding path, are compatible with all stereo amplifiers.Features1. Use convenient button terminal, can accept up to 12 AWG loudspeaker wires. 2.

About The Product1. LINEPAUDIO A967 Passive PreAmp Active Speak Volume Two-Channel Controller is small and compact, applicable to use with active speaker or PostAmp, supports full-balanced or single-ended signal I/O, equipped with a switch for easily switching I/O signal. 2. Infinitely picky about the sound quality, infinitely tolerant on music. Passive PreAmp Volume Controller makes the desktop simple. 3. Small size but great wisdom, LINEPAUDIO A967 is tiny but with a complete set of common interfaces, supports full-balanced audio signal regulation and single-ended audio signal regulation, and switches I/O signal. 4. Suitable for the decoder and speaker without volume regulation, with the balanced I/O, RCA I/O architecture and switch function enabled. Its PreAmp will not cause a loss of signal source. In general, the audio source signals out of the decoder reproduces the original signals. The large dynamic range will not cause a quality loss, but keep the original signal source intact. 5. The preferred choice of active speaker, more and more music fans are not satisfied with the sound quality performance of common multimedia speakers, but rather select professional active monitor speakers. But such speakers generally don't have a volume regulation knob, but have to use with PreAmp. Most active monitor headphones are used for the desktop near-field listening, but a common HiFi PreAmp is large and occupies a large area. Moreover, most are concerned about whether the timbre of PreAmp matches the speaker or not, whether the sound effect is ideal or not. 6. But from now on, LINEPAUDIO A967 Two-Channel Volume Controller perfectly addresses the above two concerns, LINEPAUDIO A967 is small and compact, the internal circuit architecture design will not cause a loss of sound quality, the internal power amplifier of active speaker is enough to drive the speaker, so that you can hear the most genuine timbre and quality of the speaker, free from the need of choosing a suitable PreAmp.Features1.
