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
  • Three isolated headphone outputs with individual volume controls.
  • 125 dB dynamic range with flat frequency response.
  • Durable 1/4-inch connectors, panel mounted for strength.
  • Stereo or mono monitoring.
  • Peak LED indicates headphone overload.
  • Two balanced XLR line level inputs or unbalanced 1/4-inch and 1/8-inch stereo inputs.
  • Loop Output to connect additional HX-3's in series.
  • All-metal connectors solidly mounted to the chassis for durability and RF immunity.
  • Free from "Pin-1" grounding problems.
  • Internal battery-power for up to 18 hours from two AA alkaline batteries.
  • Chassis-isolated 5 to 18 VDC input for easy external DC powering.
  • Power LED indicates low battery power.
  • High strength, extruded aluminum chassis with protective metal end panels.

 

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

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)

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).

HeadAMP - Four Output Stereo Headphone Amp Specifications:

Signal To Noise Ratio >90dB
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
Power Requirements 12V DC (Adapter included)
