Vienna Acoustics Principal Grand owner manual Power Cord Input, Master Power Switch

1 – Power Cord Input

2 – Fuse Socket (use only the supplied fuse or one that is the same type and rating only!)

3 – Master Power Switch

4– High-Level Inputs: This input derives the signal directly from the amplifiers output. This should be used when the Phono (RCA) – Plug inputs are not available.

5– Phono (RCA) – Plug Inputs: This is the most common connection input that derives the signal either from the pre-amplifiers output or the subwoofer output of an audio video pro-cessor/receiver.

Attention: If only one Phono (RCA) – Plug connection is used for the subwoofer output of an audio/video processor/ receiver, it does not matter which, either left or right, input you use. If you have a need for additional gain, it may be necessary to use a Y- Adapter to use both Left and Right labeled inputs.

6 – Adjustable Crossover (Frequency) Control: The crossover point is determined by listening. Where this ultimately sets up best is determined by the in-room performance of your main loudspeakers unless the Principal Grand is being used exclusively for LFE. In such an application the crossover should be set to the highest point, thus relying exclusively on the base control available through your audio video processor/receiver.
