Loop-Master Pedals TRS ABCDEFY 6-Way Expression Pedal / Control Signal Selector

LOOP-MASTER PEDALS TRS ABCDEFY – 6-WAY EXPRESSION PEDAL / CONTROL SIGNAL SELECTOR

One TRS input. Six independently selectable TRS outputs. Multiple routing possibilities.

The Loop-Master Pedals TRS ABCDEFY is a passive 6-way TRS selector designed for routing compatible expression pedal, auxiliary control, and other TRS connections between multiple devices.

Each of the six outputs has its own dedicated footswitch and LED indicator.

Unlike conventional A/B/C selectors, the ABCDEFY allows multiple outputs to be selected simultaneously.

Select one output, several outputs, or all six at once.

All three TRS conductors — Tip, Ring, and Sleeve — are routed through the switching system.

No MIDI, programming, or active signal processing.

WHAT IT DOES

• One TRS input with six selectable TRS outputs
• Six individual footswitches
• Independent A/B/C/D/E/F output selection
• Select one or multiple outputs simultaneously
• Routes Tip, Ring, and Sleeve
• Individual LED indicators
• Passive signal routing
• Premium jacks
• Rugged aluminum strip enclosure
• Handcrafted in the USA by Loop-Master Pedals

TRS EXPRESSION PEDAL ROUTING

Connect a compatible TRS expression pedal to the main input.

Connect the six outputs to compatible equipment with expression pedal inputs.

Use the footswitches to select which connected device receives the expression pedal connection.

Potential applications include:

• Expression pedal routing
• Multi-effects processors
• MIDI controllers with analog expression inputs
• Compatible synthesizers and keyboards
• TRS control connections
• Custom pedalboard control systems

SIX INDEPENDENT OUTPUTS

Each output has its own dedicated footswitch.

• A – TRS Output A
• B – TRS Output B
• C – TRS Output C
• D – TRS Output D
• E – TRS Output E
• F – TRS Output F

The footswitches independently connect or disconnect their respective TRS outputs.

Use a single output or select multiple outputs as your equipment and application allow.

MULTIPLE OUTPUT SELECTION

The ABCDEFY uses independent output switching rather than a one-at-a-time selector arrangement.

This means multiple TRS outputs can be electrically connected simultaneously.

IMPORTANT: Connecting multiple active expression or control inputs together may cause interaction between devices. Some equipment supplies voltage through its expression jack, and connecting those circuits in parallel may result in improper operation or possible equipment damage.

For expression pedal applications, using one output at a time is generally the safest approach unless the connected equipment is specifically designed to share the same control connection.

PASSIVE TRS SIGNAL PATH

Each TRS connection carries:

• Tip
• Ring
• Sleeve

The selector does not convert expression pedal signals, change polarity, or provide electronic buffering.

The connected equipment must use compatible TRS wiring and electrical requirements.

DIMENSIONS

• 14" × 2.2" × 1.6"
• 35.6 × 5.6 × 4.1 cm
• 356 × 56 × 41 mm

POWER

• Boss/Ibanez 2.1mm center-negative 9V DC for LEDs only
• TRS switching is passive and works without power
• Without power, the LED indicators will not illuminate

CONNECTIONS

• 1 × 1/4" TRS input
• 6 × 1/4" TRS outputs
• 9V DC connection for LED indicators

Standard TRS cables are required and are not included.

CONSTRUCTION

• Six heavy-duty footswitches
• Six individual LED indicators
• Premium TRS jacks
• Rugged aluminum strip enclosure
• Passive switching circuitry
• Handcrafted in the USA by Loop-Master Pedals

IMPORTANT COMPATIBILITY INFORMATION

This is a passive TRS routing selector, not an active expression pedal converter, MIDI controller, or electrically isolated distribution amplifier.

Expression pedals and control inputs are not universally interchangeable. Different manufacturers use different Tip/Ring assignments, resistance values, voltage ranges, and control systems.

The six outputs are not electrically isolated from one another when selected simultaneously.

Please verify compatibility before connecting multiple devices, particularly when using expression pedal inputs that supply their own control voltage.
