6.3 | Multi channel DSP Amplifier |
|
| |
| When the multi channel DSP amplifier is connected to the DSP matrix mixer it is | |||
| recommended to connect via either Amp Link connectors or the phoenix terminal inputs. The | |||
| amplifier also has XLR/TRS combo inputs in case it will be used without the DSP matrix mixer. | |||
