Product information

Description

Hosa GPM-179 is a compact audio adapter that converts a 3.5 mm TR (mini phone) plug to a 1/4 in TS (mono phone) plug. Designed to adapt a mini stereo phone plug to a mono phone output, this adapter routes the stereo left and right channels into a single mono signal. Its black finish and metal shell provide a discreet, durable connection for linking headphones, instruments, portable players and consumer audio equipment with pro or semi‑pro gear.

Advantages

The adapter provides a simple, passive conversion between 3.5 mm TR and 1/4 in TS connectors without requiring additional cables or powered converters. It preserves signal continuity while summing stereo channels into mono so that both left and right signals are present at the mono output. The compact, robust construction makes it suitable for mobile use and studio patching where space is limited.

Suitable for

  • Connecting portable audio players or smartphones to a mono instrument or mixer input
  • Adapting stereo headphone outputs for use with mono amplifiers or PA channels
  • Linking keyboards, drum machines or other consumer devices to guitar amps or mono DI inputs
  • Temporary studio patching and live sound setups requiring a mini‑to‑phone conversion

Key specifications

  • Connector A: 3.5 mm TR (mini phone), male
  • Connector B: 1/4 in TS (mono phone), male
  • Function: stereo-to-mono summing (applies mono equally to left and right)
  • Finish: black
  • Construction: compact, passive adapter (no active electronics or power required)

How to use

Insert the 3.5 mm TR male end into the source device's headphone or line output and plug the 1/4 in TS male end into the destination mono input, amplifier or mixer channel. Because the adapter passively sums stereo channels to mono, ensure source volume levels are set appropriately to avoid overloading the receiving input. Remove the adapter when not in use to protect connector contacts and prevent accidental damage.

Usage recommendations

Use this adapter for signal routing and temporary connections; it is not a substitute for balanced or dedicated stereo-to-mono summing circuits when channel separation or impedance matching is required. For permanent installations or where level matching is critical, consider using a proper summing device or a DI with stereo-to-mono capability.
