A valuable addition to Focusrite’s RedNet range of audio-over-IP interfaces, RedNet AM2 is a compact, flexible Dante-compatible stereo monitoring unit combining headphone and line outputs for monitoring of signals from the Dante network wherever required. RedNet AM2 features a 1/4" front-panel TRS headphone socket plus a pair of rear-mounted balanced line outputs with male XLR connectors for loudspeaker monitoring and other applications.
Designed to drive high or low impedance headphones at high levels, the headphone output delivers significant audio output power. The compact unit, mounted in an enclosure based around a sturdy road-worthy aluminium extrusion, is fitted with non-slip feet, and can either sit securely on a flat surface or be mounted on top of a mic stand using the standard threaded bush incorporated in the base.
RedNet AM2 includes the latest two-channel Dante receiver and provides high-quality digital to analogue conversion for accurate monitoring on loudspeakers or headphones. Two large volume control knobs are provided for Headphone and Line output levels, the latter featuring a mute button with associated LED. Other indicators show the presence of power, network and signal level.
Dual locking etherCON connectors are included to connect the network and to daisy-chain to additional network devices. The unit is powered via Power over Ethernet (PoE) or via the rear-panel barrel connector and included DC power supply. |
The PHDA02 - a reference class headphone amplifier with Stereo, Mono, and Dual Mono operation modes.
In Stereo mode, the L/R input signal is fed to the left and right earphones while the volume level is set by the Stereo/Left control. The front panel inputs provide simultaneous connection of two headphones in parallel. In Mono mode, the left and right channels are summed, and the resulting mono signal is fed to both the left and right earphones. Again, volume is governed by the Stereo/Left control. In Dual Mono mode, the left and right channels can be used independently with individual level controls for the left and right earphones.
The PHDA02 operates with all headphones with an impedance of 8 up to 200 Ohms. Impedance matching is achieved by a specially designed switchable transformer. Uncommon and costly, this solution provides superior performance, dynamic range, and signal-to-noise ratio at all loads.
Combo input sockets allow for balanced XLR and unbalanced TS headphone connection while parallel XLR outputs facilitate daisy chaining multiple units. The integrated power supply operates with mains from 100 VAC to 240 VAC.
The PHDA02 is equipped with low-noise op amps, and the output amplifiers' discrete power transistors are mounted on heatsinks. Dimensions are 1 U 9.5“.

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).
