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“.

| Palmer Monicon, and the volume is right!
With Palmer Monicon, your monitor volume is always under control. The passive mini-mixer with the oversized control is inserted between the stereo output of the notebook, PC or interface and an active monitor system and thus permits convenient and precise volume control of the monitors from the workstation. The passive circuitry with only a few components has absolutely no affect on the sound. Mute and mono buttons make it possible to mute the outputs and merge the stereo output signal into a mono master signal.
The inputs and outputs of the controller are equipped with XLR connectors and the 3.5mm stereo TRS sockets usually found on computers. Combo input sockets also permit connection with 6.3 mm TRS plugs. Thus the Palmer Monicon is compatible with both professional and consumer equipment. Genuine wood sides make the practical studio tool in its massive powder-coated sheet steel housing an elegant looking "little helper" that is a typical Palmer product.
