Stereo Zone w/ Stereo Sub-Zone Using a DLA Speaker Selector
Connect the Zone Preamp Output of the AH66T to the Audio Inputs of the ATON A275
amplifier. Using the ATON configuration software, configure the Zone Preamp Output to
FIXED. Connect the amplified output from the A275 to the Amplifier Input of the DLA
Speaker Selector. The main zone ramps the AH66T’s internal amplifier volume up/down at
preamp level using IR or RS-232 commands sent from an OLED2 Touchpad, or hand held
remote, while the sub-zone ramps volume up/down at speaker level using the Speaker
Selector.
The Speaker Selector can be controlled using its front panel buttons, IR commands from
handheld remotes or by using DLATP touchpads connected to the Speaker Selector. An
optional ATON RF remote is also available.
The diagram on the next page shows an OLED2 controlling zone one of the AH66T.
Commands from the OLED2 control the AH66T’s internal amplifier. Zone one’s preamp
output is set to FIXED and sends audio signals to the ATON A275 amplifier which then
sends its amplified output to the DLA4 Speaker Selector.
The DLA4 allows independent volume control for each speaker or speaker pair connected
to the Room outputs. In this example, Areas A and D are using Dual-Voice Coil speakers
and Areas B and C are using stereo pairs of speakers.
