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 away
from moisture, excessive sunlight and dust
