3 Overview
Your 482xl Bi-directional Audio Transcoder has two separate channels that
function independently of each other
1
:
Converting an unbalanced audio input signal to a balanced
2
audio output
signal on one channel
Converting a balanced audio input signal to an unbalanced audio
output signal on the other channel
In addition, the 482xl Bi-directional Audio Transcoder:
Lets you adjust the gain or attenuation while transcoding, to
compensate for the 14dB change between IHF audio levels and the
state-of-the-art balanced DAT input levels
Is designed with very low noise and low distortion components
To achieve the best performance:
Connect 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)
Use good quality sockets and connectors to avoid signal path
breaks
3
. Aim for Zero Ohm connection resistance
Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer 482xl
away from moisture, excessive sunlight and dust
1 As both channels function independently, you can use just one channel or both channels simultaneously
2 Balanced audio is more immune to noise and interference
3 Poor quality connectors tend to rust, which may cause breaks
