The LD Systems HPA 1 is a versatile headphone amplifier with high power output for stage, studio and home recording and is the perfect solution for wired in-ear-monitoring.. The compact device in a rugged, ergonomically shaped plastic housing with soft-touch surface and practical belt clip is very extensively equipped.

In addition to locking XLR connectors for the stereo signal L/R input, the HPA 1 has a balanced 3.5 mm stereo jack as AUX input, which can be used in parallel for clicks or playback. It is protected for safe operation against excessive input levels; a hollow pin socket with negative internal contact enables the connection of a network adapter for fixed operation.

A 3.5 mm stereo jack is provided as earphone and headphone output. Volume level and balance can be set with easy-grip knobs, a push-button switches between the summed mono and stereo signals. A full-fledged limiter is integrated for distortion-free playback and as protection against feedback.

The LD Systems HPA 1 has bi-colour LEDs to facilitate the features overview, which displays the response of the limiter during peaks and the battery status. At 165 grams, the headphone amplifier is distinctly light-weight and can be operated for up to 12 hours thanks to a high quality 9 V block battery.

The compact HX-3 Headphone Distribution Amplifier is the perfect accessory to quickly provide three high-performance stereo headphone feeds with individual level controls from line-level sources. The HX-3 can produce very high headphone levels with extremely low noise and distortion.

HX-3 Key Features

Great for radio, television, film, and music production applications, the battery-powered HX-3 accepts balanced XLR line-level inputs or unbalanced 1/4-inch and 1/8-inch stereo inputs. Its 1/4-inch loop-out can connect multiple HX-3's for additional headphone outputs. Headphones are connected to panel-mounted 1/4-inch stereo connectors.

The HX-3 has a durable aluminum chassis to withstand the punishment of field and studio environments. The unit is powered by inexpensive batteries (two-AA) or external 5-18 VDC.

The HX-3 can add headphone outputs to the 552, 302, MixPre-D, MM-1, and USBPre-2.

HX-3 Key Features List
  • Three isolated headphone outputs with individual volume controls.
  • 125 dB dynamic range with flat frequency response.
  • Durable 1/4-inch connectors, panel mounted for strength.
  • Stereo or mono monitoring.
  • Peak LED indicates headphone overload.
  • Two balanced XLR line level inputs or unbalanced 1/4-inch and 1/8-inch stereo inputs.
  • Loop Output to connect additional HX-3's in series.
  • All-metal connectors solidly mounted to the chassis for durability and RF immunity.
  • Free from "Pin-1" grounding problems.
  • Internal battery-power for up to 18 hours from two AA alkaline batteries.
  • Chassis-isolated 5 to 18 VDC input for easy external DC powering.
  • Power LED indicates low battery power.
  • High strength, extruded aluminum chassis with protective metal end panels.
