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“.

The amPlug Night Train perfectly simulates the high-gain sound of the compact VOX Night Train tube amp. Just as with the actual Night Train head, you can switch between the two preamp sounds. The BRIGHT position boosts the high-frequency range; the THICK position offers a chunkier, heavier sound. The emulated speaker cabinet circuit accurately recreates the sound of the Night Train amp being played through the matching V112NT single 12" Night Train speaker cabinet. As a finishing touch, amPlug Night Train share some of the cool looks of its namesake amplifier.

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.

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.

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.

• 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.
