The LX-2 from Radial Engineering is a passive line splitter and attenuator designed to lower hot signal levels and split one line-level input source to two line-level output paths, allowing flexible routing or parallel processing. Featuring low noise, high dynamic range, and flat frequency response, the LX-2 will not compromise signal quality.

For live sound, the LX-2 can split a mixer output to a PA and multitrack recorder. In the studio, use it to split the output of a microphone preamp. Then, record one signal with compression and one without. Manage extreme levels with the Trim pot, offering up to 10 dB of attenuation. A recessed on/off button for the Trim control prevents accidental switching.

It is equally well-suited for live and in-the-studio productions, with its 14-gauge steel enclosure and no-slip pad. For installation in 500 Series racks, J-Rak 4 and J-Rak 8 rackmount adapters are available separately. The LX-2 requires no power supply, due to its passive circuitry.

Balanced or unbalanced signals can be used. Input connectivity is available using a combo jack, compatible with XLR or 1/4” input sources. XLR connectors are used for both outputs, the direct “Thru” jack and the transformer-isolated output. Each output features a ground-lift switch, to minimize hum and buzz caused by ground loops.

Related Questions and Answers

Q: 1. There are Kopul ACH4-25MON and Kopul ACDR-35. One has 25dB of Attenuation and the other one has 35dB of Attenuation. Please clarify: When to choose the first one and when the second one?

A: Both cables will provide sufficient attenuation for use padding a line level output signal from a device such as a portable audio recorder in order to match the mic level input on a camera or device with a 3.5mm mic input. -25 dB is typically enough, but -35 dB will provide even more attenuation. A higher level of attenuation would be needed if the -25 dB attenuation level is still overloading the mic input or if more headroom is desired.

Q: 2. Would this be suitable for cutting headphone level to mic level?

A: The Sescom XLR Male to XLR Female In-Line Attenuator (-50 dB) will bring a line level signal down to mic level, although it should be noted that a headphone signal does not have the same impedance as a true line output.

Q: 3. Is the item compatible with the Canon 6D?

A: DSLR Compatibility: The ACH4-25MON is compatible with DSLR cameras that feature a 1/8 unbalanced mic level input including: Canon: EOS Rebel T2i(550D)/T3i(600D)/T4i(650D)/T5i(700D)/SL1(100D) EOS 60D/70D/7D/6D EOS 5D MK ll/MK lll EOS 1DX/1DC/1D MK lV

Q: 4. Is this compatible with android devices?

A: You can use the Kopul ACH4-25MON with an Android device but you will need to use it with a 3.5mm TRRS adapter to convert the plug from 3.5mm TRS to TRRS since smartphones have a 3.5mm TRRS connector. The Rode SC4 3.5mm TRS Female to 3.5mm Right-Angle TRRS Male Adapter Cable for Smartphones (B&H # ROSC4). Another option would be to use a similar cable that already has a TRRS connector such as the Movo Photo TCB2 XLR Female Microphone to 3.5mm TRRS Male Smartphone Adapter (B&H # MOTCB2) or the MXL Female XLR to 3.5mm Male TRRS and 3.5mm Female TRS Multimedia Adapter Cable (B&H # MXMMCABLE1).

Q: 5. Would this be able to hook line out of zoom H6 into mic input of another recorder (h1n or computer) for a back up recording of zoom h6? Or can you just use a regular 3.5mm aux cable? Thank you!

A: Yes, you can use the attenuator cable to connect the line out from the H6 into the mic input of another recorder. If the second recorder that is being used for the backup recording accepts line level input signal, then you can use a standard 3.5mm TRS to 3.5mm TRS aux cable. As an example, Zoom's H1n accepts mic and line level through its 3.5mm TRS input. Just check the specs for the audio inputs on your backup recorder to be sure of what type of signal it accepts.

Q: 6. Would I be able to use this on my BMPCC 6k Pro?

A: Yes, you can use the the line-to-mic attenuator but it's not necessary since the BMPCC 6k Pro accepts line level audio through the 3.5mm inputs.

Q: 7. Can I use this to reduce the volume of the XLR line out of a bass amplifier?

A: I honestly don't know.

Q: 8. ProAV1 Can this unit output to a laptop's 1/8 microphone input for recording audio from a mixer?

A: No. The Pro AV1 converts consumer input (1/8) to balanced out (XLR) - the opposite of what you want. Radial makes the J-ISO and Pro-ISO that will do what you want. The J-ISO uses a Jensen transformer and is the one you want for studio recording. The J-PRO is good for broadcast use for recording vocal range audio and is cheaper than the J-PRO.

Q: 9. Will this filter RFI from the output of my mixer? If used at the amp?

A: Yes it should filter

Q: 10. how do you set them up on a tascam DR-40?

A: pleasure explain your input source, including level. Otherwise it's difficult to figure out what you are asking.
