Ruth's sister International Power Cord 4 Channel Metal 8.3x5.2x3.8cm

SKU CH-X74S-8AH8Q

A passive four-channel stereo mixer with independent volume controls, ultra-low noise performance and no power supply required

  • Ultra-low noise design delivers clean audio at maximum output
  • Four independent 100K ohm potentiometers give precise per-channel volume control
  • Passive circuitry requires no battery or external power source
  • Metal chassis measuring 8.3 x 5.2 x 3.8 cm ensures durability
  • Four stereo RCA inputs and one stereo RCA output support flexible routing

Compact Four-Channel Passive Mixer

This metal stereo mixer provides four independent channels with 100K ohm potentiometers for precise volume control. It accepts four stereo RCA inputs and delivers one stereo RCA output without requiring any external power source. The passive design ensures ultra-low noise performance even at maximum output levels. Its 8.3 by 5.2 by 3.8 centimetre chassis fits easily into portable recording or streaming setups.

Check Your Connections And Signal Levels

Verify that your sources and destination equipment use stereo RCA connectors for compatibility with the four inputs and single output. The mixer operates with an input impedance range of 10K ohm to 47K ohm and an output impedance range of 2.5K ohm to 10K ohm. Confirm that your devices fall within these ranges to avoid signal loss or loading issues. Remember that the maximum gain is minus 12dB, so the unit attenuates rather than amplifies signals.

Replaces Bulkier Powered Mixers For Simple Routing

This passive four-channel unit replaces larger active mixers when you only need to combine or distribute line-level stereo sources such as instruments, media players, computers or mobile devices. The jump is worth it if you want a silent, metal-encased solution that draws zero power and occupies minimal desk space. It is not for users who require microphone preamps, equalisation, phantom power or any form of signal amplification.

Questions about this item

Does the mixer ship with cables or do I need to buy RCA leads separately?

The package contains the metal four-channel mixer only; RCA cables for the four stereo inputs and one stereo output must be purchased separately.

Which version should I choose if I need adjustable level control on every channel?

This single model provides four independent 100K ohm potentiometers, one per channel, giving individual volume adjustment across all inputs.

What does the -12 dB maximum gain mean when I connect a phone and powered speakers?

The mixer is passive, so it can only attenuate the signal up to 12 dB; it adds no amplification, and the output impedance ranges from 2.5K to 10K ohm depending on knob position.
