The end user of any amplifier in the SC may ask for internal installation program and save in non-volatile memory up to 4 different settings of the amplifier for the purpose of listening to different music genres (eg pop, rock, jazz, etc.) according to your hearing preferences.
To switch between the 4 stored in the memory of the amplifier user settings will need to purchase a set of wireless remote control DRC-4 and a receiver via radio RFC-2 (this package is optional and standard amplifiers not included).
Wireless Keychain DRC-4 is used to switch between the 4 stored in the memory of the amplifier user settings. Receiver for radio RFC-2 is connected to the input of the amplifier RJ-45 after the programming process, and performs the function of the wireless receiver from the remote control radio DRC-4.
