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 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

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.
