ART HEADAMP 6 Pro Headphone preamplifier 6 channel

Overview

The ART HeadAmp6PRO is a six-channel stereo headphone amplifier that includes a six-channel auxiliary input section that can be used to provide the popular "More-Me” function on each headphone mix. Each output channel also features a dual function BALANCE control which will pan between LEFT & RIGHT sides of the main signal bus, or vary the MIX between the main signal bus and the AUXILIARY input for that respective channel.

Bass and treble controls are included on each output channel for fine-tuning the tone. Outputs include both front and rear panel stereo 1/4-inch TRS jacks for ease of installation and quick patching capability. Two MONO select buttons on each channel select between four operating modes; 1) Stereo, 2) Mono Left, 3) Mono Right, 4) Mono Both (Left & Right) for versatile monitoring solutions.

The main outputs for each channel of the headphone amplifier are rear mounted stereo TRS jacks and are wired in parallel with the corresponding output jacks on the front panel. Front panel, rear panel, or both front and rear panel outputs can be used simultaneously to drive headphones or be used as feeds to additional headphone amplifiers in a distributed audio network.

Input options include XLR and 1/4-inch TRS balanced inputs with matching "Thru” jacks for bridging multiple HeadAmp 6 Pro units. An additional front panel stereo 1/4-inch TRS jack for quick patch override of the rear panel inputs is included for quick insertion of any stereo source. Eight-segment LED level indicators provide visual feedback of the signal level on all channels as well as the main signal bus.

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.

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).
