MyMONITOR - Personal Headphone Monitor Mixer Overview

Problem: A performer needs to hear him/herself through headphones exclusively or mixed
with the output of a mixer, CD player, tape deck, or other stereo line level source. Only the
mic signal, however, should be going to the main mixer.
Solution: Connect MyMONITOR between the mic and line source, and the mixer. The Mic
and line Monitor levels can then be adjusted for mix and volume through the headphones.
Only the mic signal will go to the board. And since MyMONITOR can be AC or battery powered,
the unit can be used on a large stage or wherever there is no AC outlet nearby. Dynamic or
condenser mics can be used since phantom power would come through the Mic Thru jack from
the mixer or other source.

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)
