Configuring the receiving channel
settings
Two RF modes (channel modes), [Wide Band] and
[Narrow Band], are available on the DWZ.
Each RF mode consists of six channels. Select the
appropriate channel according to your intended use. The
RF mode is set to [Wide Band] and the transmission
channel is set to 1 under factory default settings.
When using multiple channels (up to six), the two RF
modes, [Wide Band] and [Narrow Band], cannot be used
simultaneously. Select only one RF mode during use. In
addition, Wi-Fi and other environmental interference may
reduce the actual number of channels that can be used
simultaneously.
To select the RF mode
1 In the [Setup] screen, select [Advanced Settings].
2 Select [RF Mode Settings].
The [RF Mode Settings] screen appears.
3 Select [Wide Band] or [Narrow Band].
When the configuration is complete, the main screen
appears again.

2 Specify the channel using one of the following
methods.
When configuring settings using method A or B, turn
off all transmitters beforehand.
ASelect [Best Channel Selection]
The channel with the least interference will be
configured automatically.
BSelect [Clear Channel Scan]
The interference status of each channel in the
selected RF mode is displayed.
The lengths of the bars indicate the strength of the
interference.
Select the channel with the least interference.
CSelect [Manual Setup]
Configure the channel manually. Select the
channel you want to use.
This completes the configuration, and the main
screen appears again.
If you change the channel setting, be sure to change the
channel setting on the transmitter to the same channel. If
the receiver channel and transmitter channel are not
identical, audio will not be output.
Configuring the intelligent feedback
reduction function
The ZRX-HR70 is equipped with an intelligent feedback
reducer.
This function uses a unique algorithm that processes
signals in real time to prevent the acoustic feedback noise
that occurs when a microphone is brought in close
proximity to speaker output.
The function eliminates the need for complicated
parameter adjustments according to room size, speaker
positions, etc., and allows you to select from three
different effect levels based on you environment.
This allows you to use the system without speaker
position being a major concern. [Effect Level] is set to
[OFF] and [Apply Feedback Reducer] is set to [To All
Outputs] under factory default settings.
