Install the VS-88H2A
To rack mount the machine, attach both rack ears (by removing the screws from each side of the machine and replacing those screws through the rack ears) or place the machine on a table.
- Ensure that the environment (e.g., maximum ambient temperature & air flow) is compatible for the device.
- Avoid uneven mechanical loading.
- Appropriate consideration of equipment nameplate ratings should be used for avoiding overloading of the circuits.
- Reliable earthing of rack-mounted equipment should be maintained.
Connect the inputs and outputs
Always switch OFF the power on each device before connecting it to your VS-
88H2A. For best results, we recommend that you always use Kramer high-
performance cables to connect AV equipment to the VS-88H2A.
Connecting the audio output
To a balanced stereo audio acceptor:
