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.

Dimensions 5.5 x 5.5 x 1.75 Mounting Max Rack and Universal Rack Tray Chassis Steel Panel Brushed Aluminum Sides Cast AluminumPalmer Monicon, and the volume is right! With Palmer Monicon, your monitor volume is always under control. The passive mini-mixer with the oversized control is inserted between the stereo output of the notebook, PC or interface and an active monitor system and thus permits convenient and precise volume control of the monitors from the workstation. The passive circuitry with only a few components has absolutely no affect on the sound. Mute and mono buttons make it possible to mute the outputs and merge the stereo output signal into a mono master signal. The inputs and outputs of the controller are equipped with XLR connectors and the 3.5mm stereo TRS sockets usually found on computers. Combo input sockets also permit connection with 6.3 mm TRS plugs. Thus the Palmer Monicon is compatible with both professional and consumer equipment. Genuine wood sides make the practical studio tool in its massive powder-coated sheet steel housing an elegant looking "little helper" that is a typical Palmer product.

MyMONITOR - Personal Headphone Monitor Mixer Overview

Problem: A performer needs to hear him/herself through headphones exclusively or mixed
with the output of a mixer, CD player, tape deck, or other stereo line level source. Only the
mic signal, however, should be going to the main mixer.
Solution: Connect MyMONITOR between the mic and line source, and the mixer. The Mic
and line Monitor levels can then be adjusted for mix and volume through the headphones.
Only the mic signal will go to the board. And since MyMONITOR can be AC or battery powered,
the unit can be used on a large stage or wherever there is no AC outlet nearby. Dynamic or
condenser mics can be used since phantom power would come through the Mic Thru jack from
the mixer or other source.
