SAFETY WARNINGS
1. This device is intended for indoor use only. Do not expose this device to water or
moisture of any kind.
2. Ensure that the wire connections are clean, with no stray wire strands anywhere.
3. Double check all connections before applying power.
4. Do not provide a speaker load lower than 4 ohms to the amplifier. Doing so can
cause damage to the amplifier and could result in a fire.
5. Do not install or operate in close proximity to a heat source, such as a furnace,
radiator, or fireplace.
CONNECTION NOTES
The Bluetooth Audio receiver and the 2x RCA stereo analog jacks are in parallel. If an
audio source is applied to both inputs they will be mixed with higher volume levels.
The 3.5mm TRS jack and the internal hard wired terminals are also in parallel. If an
audio source is applied to both inputs they will be mixed with higher volume levels.
The 3.5mm jack/hardwired terminals have priority over the Bluetooth/RCA inputs. If an
audio source is present on both the 3.5mm/hardwired input and the Bluetooth/RCA
input, only the source(s) from the 3.5mm/hardwired input will be heard.
Note that combining audio sources in this way is not recommended and could cause
damage to your equipment. The only proper way to mix audio signals is using an audio
mixer. Therefore we highly recommend against applying an audio signal to both the
3.5mm and hardwired inputs. Similarly, we recommend to not use both the Bluetooth
receiver and RCA jacks at the same time.
