Overview
The 482xl is a high−performance audio transcoder for balanced and unbalanced stereo audio signals. The unit has two separate channels (both function independently; use just one channel or both channels simultaneously) that convert:
- An unbalanced audio input signal to a balanced audio output signal on one channel Balanced audio is more immune to noise and interference.
- A balanced audio input signal to an unbalanced audio output signal on the other channel
In addition, the 482xl Bi-directional Audio Transcoder features:
- Gain or attenuation adjustments while transcoding, to compensate for the 14dB change between IHF audio levels and the state-of-the-art balanced DAT input levels
- Very low-noise and low-distortion components.
Defining the 482xl Bidirectional Audio Transcoder
This section defines the 482xl.
Connecting the 482xl
Always switch off the power to each device before connecting it to your 482xl. After connecting your 482xl, connect its power and then switch on the power to each device. To convert the audio input signals at the UNBAL IN (to the balanced audio output) and the BALANCED IN (to the unbalanced audio output) connectors, as the example illustrated in Figure 2 shows, do the following:
- Connect the unbalanced audio source (for example, an unbalanced audio player) to the UNBAL IN 3-pin terminal block connector.
- Connect the BALANCED OUT 5-pin terminal block connector to the balanced audio acceptor (for example, a balanced audio recorder).
- Connect the balanced audio source (for example, a balanced audio player) to the BALANCED IN 5-pin terminal block connector.
- Connect the UNBAL OUT 3-pin terminal block connector to the unbalanced audio acceptor (for example an unbalanced audio recorder).
- Connect the 12V DC power adapter to the power socket and connect the adapter to the mains electricity (not shown in Figure 2).
Adjusting the Audio Output Level
The 482xl Bi-directional Audio Transcoder comes factory pre-set for 1:1
transparency. Readjusting the 482xl Bi-directional Audio Transcoder upsets
this transparency. However, if necessary, you can fine-tune both channels’
audio output levels.
To adjust the appropriate audio output levels:
- Insert a screwdriver into one of the four small holes on the lower side of the 482xl Bi-directional Audio Transcoder, enabling access to the appropriate trimmer.
- Carefully rotate the screwdriver, adjusting the appropriate audio output level, as required.
