Passive 2-Channel Splitter Klark Teknik DS 20 — passive audio splitter, dual output

The Klark Teknik DS 20 is a passive 2-channel audio splitter designed to duplicate balanced signals without the need for active electronics or external power. It provides two isolated outputs per channel, allowing secure routing of line-level or instrument signals to multiple destinations while maintaining signal integrity. The compact, rack-friendly design and robust passive circuitry make the unit suitable for live sound, rehearsal spaces and studio environments where straightforward, reliable splitting is required.

Advantages

The passive design eliminates the need for power, reducing points of failure and simplifying setup. Isolation between outputs helps prevent ground loops and reduces the risk of noise when sending the same signal to different devices. The unit preserves source level and impedance characteristics appropriate for line-level and many instrument signals, offering straightforward duplication without coloration from active circuitry.

Suitable for

• Distributing line-level outputs to multiple mixing desks or recorders
• Sending instrument or DI signals to FOH and monitors simultaneously
• Rehearsal rooms where several devices need the same input source
• Studio setups requiring simple passive signal splitting for routing

Key specifications

• Passive two-channel splitter with dual isolated outputs per channel
• Balanced-signal handling suitable for line-level and many instrument sources
• Compact, rack-friendly mechanical format for stage and studio use
• No power supply required; entirely passive signal path
• Low insertion loss and designed to minimize noise and ground-loop problems

How to use

Connect the source device to the channel input using a balanced cable where possible. Route each of the two isolated outputs to the desired destinations such as a mixing console and a recorder or monitor system. Ensure cabling is in good condition and use balanced connections to maximize noise rejection. Because the splitter is passive, there is no power-up sequence; simply connect and route signals as needed. If using unbalanced instrument outputs, check levels and impedance compatibility before connecting to avoid signal degradation.

Usage recommendations

Use balanced cables for best noise rejection and keep cable runs as short as practical. For critical low-level signals or very long cable runs, consider an active splitter or distribution amplifier to maintain headroom and drive capability.
