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).

IMD (SMPTE) 0.01%
Maximum Input Level +14dBV
Maximum Output Level 20dB per channel
Output Impedance 51 Ohms per channel
Output Connectors Four stereo 1/4? headphone outputs

Total Harmonic Distortion | 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.

Overview
With Sennheiserʼs HDVD 800, sound is perfect. The HDVD 800 is able to connect with digital sources and is equipped with a high-quality Burr-Brown digital/analog converter (DAC) that converts digital audio data into analog signals with a resolution of 24 bits and a sampling rate of up to 192 kHz. This enables the HDVD 800 to transmit the entire frequency spectrum of high-end audio sources without any loss of frequencies.
In addition to the symmetrical inputs, the HDVD 800 also has an asymmetrical input socket; incoming signals are symmetrized before further processing takes place. Digital sources can be connected to the rear of the unit via an XLR (AES/EBU) input, optical and coaxial (S/PDIF) digital inputs or USB. All digital inputs accept signals up to 24 bit at 192 KHz*. Designed and manufactured in Germany, this high-end, solid-state amplifier harmonize perfectly and deliver an ultimate acoustic performance when paired with any of Sennheiserʼs audiophile headphones.
Features
D/A transducer for all common formats up to 24 bit / 192 kHz
D/A transducer can be used for CD and DVD players
AES/BU, S/PDIF, USB inputs
Symmetrical (XLR) and asymmetrical (RCA) analog inputs
Symmetrical output
Sockets for four sets of headphones (two of which symmetrical)

The amPlug Night Train perfectly simulates the high-gain sound of the compact VOX Night Train tube amp. Just as with the actual Night Train head, you can switch between the two preamp sounds. The BRIGHT position boosts the high-frequency range; the THICK position offers a chunkier, heavier sound. The emulated speaker cabinet circuit accurately recreates the sound of the Night Train amp being played through the matching V112NT single 12" Night Train speaker cabinet. As a finishing touch, amPlug Night Train share some of the cool looks of its namesake amplifier.
