2 to 1 (2 in 1 Out) XLR Audio Signal Switcher, Power Amplifier Selection Switch, Suitable for CD Players, Radio Stations, Decoders, Power Amplifiers, and Active Speakers (XLR 2-1)

It is a selector for multiple audio sources in a home audio system. The 2-in-1-out version is specifically designed for customers who have 2 XLR music audio source devices suitable for L/R channel devices. For example, CD players, DVD players, radios, decoders and other sound sources, as well as switching between power amplifiers and active loudspeakers, and between pre- and post-amplifiers.It is a selector (2 in and 1 out), 2 stereo XLR inputs, selects 1 output, not a mixer, cannot be input at the same time (AB cannot be input at the same time, only one channel can be selected for operation).Connect output cables from various home audio devices to the XLR input on our unit (located on the rear panel). Easily switch between different audio sources by turning a knob on the front panel.Audio format: Balanced analogue signalConnection cable: Balanced audio cable (XLR audio cable)This eliminates the hassle of repeatedly plugging and unplugging cables, prevents wear and tear on jack contacts, and makes it easier to compare audio equipment.Model: XLR 0201 HG Net product weight: 1.93 lb./ 875 gPackaging weight: 2.33 lb./1055gSwitcher size: 6.77×7.4×2.56 in (17.2×18.8×6.5 cm)Package size: 9.65×8.27×3.54 inches (24.5×21×9 cm)Packing List:XLR audio switcher×1Notice:●The speaker may make a "pop" sound when switching. This issue is not related to the switch. It is related to the DC potential difference between the front and rear of the switch. Whether it is pure DC coupling or capacitive isolation, as long as there is a potential difference, there will be a "pop" sound, and the size of the sound is proportional to the potential difference. Neither mechanical switches nor relay switches are immune. The relay closing time is short and the pulses are sharper. Carefully designed front and rear panels make switching noise inaudible. If you encounter this problem, you can set the amplifier tone to "0" or turn the amplifier off and then on again.●Hot and cold end switching. The shielding layer is directly connected without switching and connected to the shell. It is suitable for use when all equipment is standardized.●About ground loops: The ground wires of all the equipment that make up the entire audio system form one or more closed loops. The electromagnetic waves in space pass through the plane formed by this loop, and the ground wires will induce noise currents. If this happens If the specifications of your equipment are not good (usually the unbalanced balance circuit causes audio signal current in the shielding layer), then the noise current will superimpose the audio current to form noticeable noise. Reasons for the formation of ground loops: the shell is connected to a safety ground wire, the equipment shares a DC power supply, multiple preamplifiers share a signal source, multiple signal sources share a preamplifier, and multiple decoders share a digital source (CD player or digital broadcaster) digital output), multiple digital sources share a decoder (non-fiber), etc.; this allows the ground wires to have the opportunity to form a closed loop. Solution to the problem: First of all, do not use false balanced equipment. The so-called false balance means that the socket is balanced. In fact, the cold end may be short-circuited to ground. Use an active switcher. Isolators can be used for public performances, but audiophiles use isolators with caution! Analog Era The silicon steel sheet industry has ended long ago. Modern industry can no longer produce audiophile-grade audio amplifiers and can only buy old transformers.

• It is a selector for multiple audio sources in a home audio system. Suitable for two-channel HIFI stereo L/R equipment. For example, CD, DVD, radio, decoder and other audio sources, as well as switching between power amplifier and active speakers, pre-amplifier and post-amplifier.
• It is a selector (2 in and 1 out), not a mixer, and cannot be input simultaneously (AB cannot be input simultaneously, only one channel can be selected to operate).
• Focus on the audio equipment, it's a good idea to avoid plugging and unplugging audio cables frequently and make your audio system more professional.
• Just turn the knob to select, easy to install. Pure switch box design, no power amplifier function, no volume control, no power circuit, does not affect sound quality.
• Net weight 875g, silver plated shielded cable, gold plated XLR terminal, CNC machined aluminium alloy shell, CNC machined solid metal knob, shell brushed process, sturdy and durable.
