LA AUDIO CAN-D HEADPHONE AMPLIFIER w- DELAY

You?re mixing FOH for a gig. That means the speakers are over there,
and you?re over here.Is it any wonder that your headphones sound confusing?
We all know that even short distances cause time delays. As a consequence,
listening on headphones when you?re any distance from the stage will leave you
with a confused mess of direct and delayed sound.
Enter Can-D. It?s simple really; Can-D delays your headphones so that they match
the sound from the speakers. With delay times of up to 678ms, you can be 226m
from the stage and still wallow in the sweet sound of time-coherent cans.
And if you like your cans exceptionally loud, you?ll be happy to know that with Can-D?s
substantial headphone amplifier, 9 out of 10 engineers found full volume to be 'unbearably
loud'. 
Of course, Can-D is rock-solid and tour-proof; its internal PSU and solid aluminium case
ensure it?s ready for anything you can throw at it. Or anything you can throw it at.

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).

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.

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.
