The 228 from Aphex, is an eight-channel, unidirectional, unbalanced to balanced line level converter. The unit is perfectly suited to both studio and live environments, especially with the gaining popularity of multi-channel sound, where there is the need to connect "consumer/semi pro" equipment within high-end audio installations.

To maintain audio source integrity, the 228 pairs ground loop isolating unbalanced inputs, with high-voltage impedance balanced outputs. Extensive monitoring of the signal flow is provided by front panel VU meters that indicate audio presence/level, and clip overload, on a per channel basis.

Individual levels can also be finely adjusted using dedicated front-panel trim pots, for settings anywhere between reference level and unity gain. For theatre applications, the front lights can be dimmed as desired.
