24-Channel Analog Switcher – DB25 Fully Balanced Studio A/B Line Select

This professional 24-channel analog switcher provides simple, reliable and transparent routing for demanding studio environments.

The unit features 24 balanced channels, arranged as two independent input banks, Input A and Input B, feeding a common 24-channel output bank.

Each channel can be selected individually using the front-panel toggle switches, allowing fast and intuitive A/B switching without the complexity of a digital control system.

Bi-Directional Operation

The switching system is fully bidirectional, meaning it can operate in either direction depending on how the unit is connected in your studio.

It can be used as a:

• 24-channel A/B source selector
• 24-channel destination selector
• Analog routing switch
• Studio line switcher
• A/B comparison system
• Analog patchbay alternative or expansion

Fully Balanced Analog Signal Path

All 24 channels use a fully balanced analog signal path, making the unit suitable for professional balanced studio equipment.

There are no active audio electronics in the signal path, providing a straightforward and transparent passive switching architecture.

Front-Panel Toggle Switching

Each channel has its own front-panel toggle switch, giving you immediate visual and physical control over the routing.

This is particularly useful in mastering, mixing and recording environments where quick A/B comparison and reliable manual routing are required.

DB25 / DSUB Connectivity

The rear panel uses DB25 / DSUB connectors with Tascam-standard analog pinout, making the unit easy to integrate with professional interfaces, converters, patchbays, consoles and outboard equipment.

24 Channels / 12 Stereo Pairs

The 24 balanced channels can be configured as 12 stereo pairs, making the switcher particularly suitable for stereo mastering and mix-bus applications.

The total routing capacity is:

24 × Input A + 24 × Input B → 24 Outputs

The unit can also be used in the reverse direction because of its bidirectional architecture.
