Pioneer VSX-1022-K User Manual

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.
Phase Control technology provides coherent sound 

reproduction through the use of phase matching 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.

 

•

Phase 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, then the sound will be ‘out 

of phase’ and an unreliable sound image will be produced.

•

If your subwoofer has a phase control switch, set it to the 

plus (+) sign (or 0°). However, the effect you can actually 

feel when Phase Control is set to ON on this receiver 

depends on the type of your subwoofer. Set your subwoofer 

to maximize the effect. It is also recommended you try 

changing the orientation or the place of your subwoofer.

•

Set the built-in lowpass filter switch of your subwoofer to 

OFF. If this cannot be done on your subwoofer, set the 

cutoff frequency to a higher value.

•

If the speaker distance is not properly set, you may not have 

a maximized Phase Control effect.

•

The Phase Control mode cannot be set to ON in the 

following cases:

-

When the PURE DIRECT mode is switched on.

-

When the headphones are connected.

You can have the receiver automatically use 6.1 or 7.1 

decoding for 6.1 encoded sources (for example, Dolby Digital 

EX or DTS-ES), or you can choose to always use 6.1 or 7.1 

decoding (for example, with 5.1 encoded material). With 5.1 

encoded sources, a surround back channel will be generated, 

but the material may sound better in the 5.1 format for which 

it was originally encoded (in which case, you can simply 

switch surround back channel processing off).

•

With a 7.1-channel surround system, audio signals that 

have undergone matrix decoding processing through 

surround back channel processing to which the Up Mix 

function is added are output from the surround back 

speakers.

 

the surround back channel options.
Each press cycles through the options as follows:

•

 – Matrix decoding processing for generating 

the surround back component from the surround 

component is turned on.

•

 – Matrix decoding processing for generating 

the surround back component from the surround 

component is switched automatically. Matrix 

decoding processing is only performed when surround 

back channel signals are detected in the input signals.

•

 – Matrix decoding processing for generating 

the surround back component from the surround 

component is turned off.

In a 7.1-channel surround system with surround speakers 

placed directly at the sides of the listening position, the 

surround sound of 5.1-channel sources is heard from the side. 

The Up Mix function mixes the sound of the surround 

speakers with the surround back speakers so that the 

surround sound is heard from diagonally to the rear as it 

should be.

•

Using the Up Mix function is effective when the speakers in 

the 7.1-channel surround system are set up as 

recommended in the example on 

page 11

.

•

Depending on the positions of the speakers and the sound 

source, in some cases it may not be possible to achieve 

good results. In this case, set the setting to OFF.

If you want to turn this function on, perform steps 1 and 

2 again.

•

When set to ON, the   (Up Mix) indicator on the front 

panel lights.

•

Set to ON regardless of this setting when playing DTS-HD 

signals.

•

May automatically be set to OFF even when set to ON, 

depending on the input signal and listening mode.

•

If the Network Standby is set to ON or Standby Through 

is not set to OFF, you may not be able to set the Up Mix 

function.
