• Provide a clean, noise-free transition during gain setting changes
• With their outstanding audio specifications, ensure transparent
performance even in the most critical broadcast applications
• Have 8 and 16 channels respectively, each of which is independent
• Let you control the amplifier gain of the Left and Right channels—
together or separately—via the front panel buttons, or remotely via RS-232 or
RS-485
• Let you daisy-chain up to 15 machines in a single system using RS-485
or RS-232, allowing control of up to 240 stereo audio channels!
• Store and recall up to 15 configuration setups via the non-volatile
memory, using the front panel buttons, or remotely via RS-232 or RS-485
• Include a bright 7-segment LED display on the front panel, showing the
gain of the selected channel (that is, its left and right decibel status)
• Include easy-to-connect detachable terminal block connectors
• Are housed in a rugged, professional 1U rack mountable enclosure and
ship with Windows®-based software
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 that may
adversely influence signal quality and positioning your Kramer VA-8xl or
VA-16xl in a location free from moisture and away from excessive sunlight
and dust
