HeadAMP - Four Output Stereo Headphone Amp Overview
Most home recordings involve from one to four people, any or all of whom are
going to need headphone monitoring. The monitor amp would be connected
to the tape deck?s headphone output or a mixer output so that the performers
can hear themselves and each other. Of course the same application can apply
to band rehearsals and even home entertainment. HeadAMP provides amplification
and individual volume control for up to 4 headsets. It can be driven by either line-
level or headphone amplifier signals (mono or stereo).

Overview
Sound can be perfected with Sennheiserʼs HDVA 600. Delivering authentic sound in its purest form, listeners are treated to a world of sheer listening pleasure. Years of knowledge in audio engineering and innovations in acoustic amplification, resulted in the creation of the HDVA 600. The consistently symmetrical signal processing and extremely low harmonic distortion guarantees an absolutely precise sound. Also, thanks to their pre-amp performance, they are easy to adjust and be connected directly to speakers for optimum audio amplification. In essence, the HDVA 600 provides a spectacular listening experience when paired with any Sennheiserʼs audiophile headphones.
Features
Consistently symmetrical signal processing for maximum sound quality
Symmetrical inputs and outputs simplify integration into a system
High-end ALPS quadruple potentiometer achieve perfect channel equality
Variable gain factor (five stages) for optimized use of low impedance headphones
Sophisticated metal housing to protect against signal scatter and vibration
Solid controls turned from solid metal, providing the utmost in long-term stability |

4 kg | 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.

| 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.
