Synchronized operation with a KURO LINK-compatible 
Pioneer flat panel TV or Blu-ray disc player or with a 
component of another make that supports the KURO 
LINK function is possible when the component is 
connected to the receiver using an HDMI cable.

For details about concrete operations, settings, etc., refer 
to the operating instructions for each component.

• You cannot use this function with components that 

do not support KURO LINK.

• We do not guarantee this receiver will work with 

Pioneer KURO LINK-compatible components or 
components of other makes that support the KURO 
LINK function. We do not guarantee that all 
synchronized operations will work with components 
of other makes that support the KURO LINK function.

• Use  a  High  Speed HDMI™ cable when you want to 

use the KURO LINK function. The KURO LINK 
function may not work properly if a different type of 
HDMI cable is used.

You can use synchronized operation for a connected flat 
panel TV and up to four (VSX-23TXH)/three (VSX-21TXH) 
other components.

Be sure to connect the flat panel TV’s audio cable to the 
audio input of this unit.

For details, see Connecting your TV and playback 
components on page 24.

• When connecting this system or changing 

connections, be sure to switch the power off and 
disconnect the power cord from the wall socket.
After completing all connections, connect the power 
cords to the wall socket.

• After this receiver is connected to an AC outlet, a 2 

second to 10 second HDMI initialization process 
begins. You cannot carry out any operations during 
initialization. The HDMI indicator on the display unit 
blinks during initialization, and you can turn this 
receiver on once it has stopped blinking.

• To get the most out of this function, we recommend 

that you connect your HDMI component not to a flat 
panel TV but rather directly to the HDMI terminal on 
this receiver.

• VSX-23TXH only: To use the KURO LINK function, 

connect this receiver and flat panel TV using the 
HDMI OUT 1 terminal. Connecting the KURO LINK 
compatible component using the HDMI OUT 2 
terminal may result in malfunction. If this happens, 
turn off the KURO LINK compatible component’s 
KURO LINK setting.

• While  the  receiver is equipped with four (VSX-23TXH)/

three (VSX-21TXH) HDMI inputs, the KURO LINK 
function can only be used with up to three DVD or 
Blu-ray disc players or up to three DVD or Blu-ray disc 
recorders.

• Connect the TV directly to this receiver. Interrupting a 

direct connection with other amps or an AV converter 
(such as an HDMI switch) can cause operational 
errors.

• Only connect components (Blu-ray disc player, etc.) 

you intend to use as a source to the HDMI input of 
this receiver. Interrupting a direct connection with 
other amps or an AV converter (such as an HDMI 
switch) can cause operational errors.

• When KURO LINK is set to ON, HDMI Input is 

automatically set to OFF.

• If a listening mode other than AUTO SURROUND, 

ALC, DIRECT, PURE DIRECT or STEREO is selected 
while the PQLS effect is enabled, the PQLS effect is 
disabled.

• When  this  receiver is connected by HDMI cable to a 

Pioneer player that is compatible with the PQLS 
function via HDMI connection and HDMI 
reauthentication is performed (the HDMI indicator 
blinks), the PQLS effect is enabled and the listening 
mode is set to AUTO SURROUND if a listening mode 
other than AUTO SURROUND, ALC, DIRECT, PURE 
DIRECT or STEREO is selected.

• When  the  receiver’s KURO LINK is turned ON, even 

if the receiver’s power is in the standby mode, it is 
possible to output the audio and video signals from a 
player via HDMI to the TV without producing sound 
from the receiver, but only when a KURO LINK-
compatible component (Blu-ray disc player, etc.) and 
compatible TV are connected. In this case, the 
receiver’s power turns on and the power and HDMI 
indicators light.
