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.

| LDHPA6 6-Channel Rackmount Headphone Amplifier
The LD Systems HPA 6 is a highly flexible 1U 19" rack format headphone amplifier with 6 fully independent channels and comprehensive features for a wide range of professional audio monitoring applications.
Each channel provides a 6.3 mm TRS headphone output on the front panel with level control, mono/stereo switching, discrete left/right muting and a 6.3 mm TRS Aux input with Main/Aux balance control for mixing in further signal sources. Four-segment LED meters permit visual output level monitoring, and two 6.3 mm TRS outputs per channel on the rear allow for connecting a total of 18 headphones.
The HPA 6\'s main section features a master level control with eight-segment LED metering and 6.3 mm TRS input to mix in an additional source with all channels. The rear panel provides the main stereo inputs on balanced XLR and 6.3 mm TRS connectors and stereo outputs for daisy chaining multiple units.

| 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.
