Pioneer VSX-918V-K, VSX-818V-K manual Better sound using Phase Control

025 minute guide

You can also choose to view the settings by selecting individual parameters from the Analyzed Data Check screen:

•Speaker Setting – The size and number of speakers you’ve connected (see page 42 for more on this)

•Speaker Distance – The distance of your speakers from the listening position (see page 45 for more on this)

Better sound using Phase Control

This receiver’s Phase Control feature uses phase correction measures to make sure your sound source arrives at the listening position in phase, preventing unwanted distortion and/ or coloring of the sound (see illustration below).

•Channel Level – The overall balance of your speaker system (see page 44 for more on this)

•Acoustic Cal EQ – Adjustments to the frequency balance of your speaker system based on the acoustic characteristics of your room (see page 40 for more on this)

Press RETURN after you have finished checking each screen. When you’re finished, select SKIP to go back to the System Setup menu.

Other problems when using the Auto MCACC Setup

If the room environment is not optimal for the Auto MCACC Setup (too much background noise, echo off the walls, obstacles blocking the speakers from the microphone) the final settings may be incorrect. Check for household appliances (air conditioner, fridge, fan, etc.), that may be affecting the environment and switch them off if necessary. If there are any instructions showing in the front panel display, please follow them.

•Some older TVs may interfere with the operation of the microphone. If this seems to be happening, switch off the TV when doing the Auto MCACC Setup.

Phase Control technology provides coherent sound reproduction through the use of phase matching1 for an optimal sound image at your listening position. The default setting is on and we recommend leaving Phase Control switched on for all sound sources.

•Press PHASE (PHASE CONTROL) to switch on phase correction.

Note

1Phase matching is a very important factor in achieving proper sound reproduction. If two waveforms are ‘in phase’, they crest and trough together, resulting in increased amplitude, clarity and presence of the sound signal. If a crest of a wave meets a trough (as shown in the upper section of the diagram above) then the sound will be ‘out of phase’ and an unreliable sound image will be produced.
