bus to save energy, DJs may experience changes in the audio output level caused by such power
fluctuations on the USB bus. Powering the high-speed USB hub separately secures the audio
output level with any configuration, and prevents compatibility issues on some laptops whose
USB ports’ voltage is too low.
5) What makes DeeJay Trim 4&6 different than the DJ Console
Rmx’s integrated audio?
a) DeeJay Trim 4&6 is more versatile, featuring:
- 2 audio modes: 2 in/6 out audio mode in addition to the 4 in/4 out mode
DeeJay Trim 4&6 has a 2 in/6 out mode in addition to the standard 4 in/4 out mode, allowing you
to export a computer mix to a 6-channel analog mixer.
- A built-in high speed USB hub
The USB 2.0 hub supports the connection of 3 additional USB devices, including USB control
surfaces (such as DJ Control Steel or other MIDI controllers), or external USB storage devices
(hard drives, USB keys).
- An included external power supply
The external power supply protects the audio level from fluctuations of the computer’s USB bus.
b) DeeJay Trim 4&6 is more powerful, with preamplifiers on the audio inputs:
DeeJay Trim 4&6 has preamplifiers to set gain and attenuation on the 4 input channels, to
support:
- high-level output sources, such as Pioneer CDJ players; and
- low-level output sources, such as phono level turntables with a low level cartridge.
On DeeJay Trim 4&6, you just turn the preamplifier knobs to adjust the gain level.
c) DeeJay Trim 4&6 offers more precise audio adjustment, with VU-meters on the audio
inputs or outputs:
The VU-meters allow the DJ to easily visually verify the audio level of each stereo source, for
example, and instantly see if an input is misconnected.
