A single subwoofer is driven from the 0.1/Lfe channel output of a multichannel processor/monitor controller. For increased dynamic range and
headroom, multiple subwoofers can be connected in series as described in Section
5
.
5
and
5
.
6
. All panel settings must be set independently for each
subwoofer.
The choice of loudspeaker model and the number of subwoofers required in any system is dependent on room size, mix format and target
calibration level at the listening position. Diagram 12 can be used as a guide to determine suitable partnering system elements from the
ATC
Professional product range. Please refer to the format developer guidelines when specifying hardware for Immersive Audio and Surround systems.
Diagram 13 – Typical Multichannel System wiring. Depending on the Monitor Controller output level and number of subwoofers, the Gain switches
may need to be set to 6dB. Further subwoofers can be added to the system using the same “Daisy Chain” method shown. The system shown is an
example and other configurations are available.
Recommended initial settings for the Studio Control Subwoofer when used in a multichannel system are shown in Diagram 14.
