As long as the specification of the amplifier is capable of driving a 70V load while running each amp channel as discrete individual amp channels, you can configure a Q-SYS network amplifier to drive a 70V load in standalone mode. Note that there is no specific setting for 70V operation - the operation is determined by the speaker profile that is wired to the Amp Output component.
- The amp must have local analog inputs so audio can feed directly to the amp output.
- For the amp to continue operation as a discrete 4-channel 70V amplifier while in Standalone Mode, the amp properties must have the Standalone Mode property set to a "One-to-One" configuration prior to deployment. This tells the amp that each local input is to feed the corresponding output directly.
- Once the amp is configured in the design, the design needs to be deployed to a Core that is connected to the amplifier via the Q-LAN network. After the deployment, the amp can be removed from the network to engage Standalone Mode.
- Once engaged, the local inputs feed the amplifier output as the network audio channels are no longer available. Audio will now feed the 70V speaker wired to the physical amp output while using the speaker profile deployed in the amplifier's DSP.
The DPA4.3Q is capable of driving 70V in a 4-Channel (A B C D) configuration. The example shown has the AD-C6t speaker (QSC 6”, 70v, ceiling speaker) wired to the Amp Output component. The speaker profile is sent to the amp’s DSP when the design is deployed.
