2-Way DB25 8-Channel Balanced Studio Splitter / Combiner – Passive DSUB Analog Mult Box (1-In / 2-Out)

Do not find your studio gear? Feel free to ask!

The 2-Way DB25 8-Channel Balanced Studio Splitter / Combiner is a fully passive analog signal distribution unit built for professional studio environments. It takes one 8-channel balanced input via DB25 DSUB and splits it into two identical duplicate outputs — with no active components, no power supply, and no coloration.

1-In / 2-Out Passive Mult

Using industry-standard parallel wiring, this unit delivers two duplicate copies of your 8-channel DSUB source simultaneously. Feed two interfaces, two sets of outboard gear, or two recording destinations from a single output — cleanly and reliably. This is the same passive mult approach used by leading pro audio manufacturers including Redco and others.

Fully Balanced, Line-Level Signal Integrity

Every channel is fully balanced and operates at professional line level. Balanced connections actively reject common-mode noise and interference, ensuring clean, transparent signal transfer regardless of cable length or surrounding RF conditions.

DSUB DB25 Connectivity

The unit uses industry-standard DB25 connectors, compatible with pro audio gear from API, SSL, Neve, Avid, MOTU, RME, and other manufacturers following the Tascam/Yamaha DB25 pinout standard. Drop-in integration into existing rack setups — no adapters needed.

Typical Use Cases

• Splitting DAW interface outputs to two sets of outboard gear simultaneously
• Feeding two recording interfaces from a single analog source
• Parallel compression across 8 channels
• Dual monitoring setups and studio patchbay expansion
• Broadcast and live sound signal distribution

A note on “Combiner” functionality: This unit is a passive parallel mult — it does not mix or sum two independent signals. The “combiner” term refers to its bidirectional usability: the same unit can be oriented so that two outputs feed back into a single destination, for example when consolidating two identical signal paths or running redundant parallel chains into one input. It is not designed to merge two different audio sources into one output. For active signal summing or mixing, a dedicated summing mixer or active combiner is required. If you are unsure whether this unit fits your specific signal flow, contact us — we are happy to advise or build a custom solution tailored to your setup.
