Achieving the best performance means:

Connecting only good quality connection cables, thus avoiding interference,

deterioration in signal quality due to poor matching, and elevated noise

levels (often associated with low quality cables)

Avoiding interference from neighboring electrical appliances, making sure

not to block the ventilation holes, and positioning your VP-727A-BA away

from moisture, excessive sunlight and dust
