| Content | 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.

Maybe you want to work out a lick with your MP3 player without taking the time to set up your amp. You want to play guitar right now. amPlug is the answer. Simply plug this palm-sized headphone guitar amp directly into your guitar, and enjoy serious guitar sound anywhere, anytime. VOX amPlug AC30 is based on a vintage VOX AC30. Even with its ultra-compact size, amPlug AC-30 perfectly reproduces the complex and warm distortion that is distinctive of a vacuum tube. Using all new analog modeling technology, amPlug delivers full-fledged amp sound. With its completely analog design, great care was also taken with amPlug's gain circuitry. The "AC30" uses two natural-sounding gain stages to reproduce the distinctive AC30 tone. Even the circuit response of the original amp is simulated completely. The simulation extends not only to the response of the tone circuits, but also to the way in which the high frequency and gain are affected when you turn down the volume control of the guitar. Every detail has been faithfully reproduced. With up to fifteen hours of battery life, it's easy to take amPlug anywhere. In addition to practicing at home, it's a great way to warm up before a live performance or on the road. And amPlug is not just a convenient way to get great guitar sound.

Terminals: Phone Jack/AUX In Jack | Palmer 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.
