👎 Cons

  • The auxiliary outputs and inputs are unbalanced, which may be more susceptible to noise over longer cable runs compared to balanced connections.
  • Specific details on the type or adjustability of the low-cut filters are not provided, limiting understanding of their precise functionality.
  • The 12V phantom power is useful but may not be sufficient for all condenser microphones, as some require 48V.
