Frequently Asked Questions - N-8 DI Phoenix Audio
What is the N-8 DI used for?
The N-8 DI is an 8-channel direct injection box that converts unbalanced instrument or line level signals to balanced microphone level for connection to mixing consoles, interfaces, or PA systems.
Can I connect a keyboard directly to the N-8 DI?
Yes, keyboards, guitars, basses, and other line or instrument level sources can be connected via the 1/4" TRS inputs. Use the input impedance selector to match your source (1 MΩ for instruments, 10 kΩ for line).
Does the N-8 DI require phantom power to operate?
Yes, the N-8 DI is an active DI and requires 48V phantom power from a mixer, audio interface, or dedicated phantom power supply via the XLR outputs.
What should I do if I hear a ground hum or buzz?
Engage the ground lift switch on the affected channel to break the ground loop between the input source and the mixer. This often eliminates hum and buzz.
How do I connect the N-8 DI to a PA system?
Connect your instrument to the 1/4" TRS input of the corresponding channel, then connect an XLR cable from the output to a mixer or PA system input with phantom power enabled.
Why is there no sound when I plug in my guitar?
Check that phantom power is enabled on your mixer/interface. Verify the XLR cable is connected securely and the input selector is set correctly. Also, ensure the pad switch is not engaged if your signal is too low.
Can I use the N-8 DI to split a signal to two destinations?
The N-8 DI provides a single balanced output per channel. For splitting, you can use a Y-cable or connect additional gear, but the standard application is direct injection to one console or interface.
How do I clean and maintain the N-8 DI?
Wipe the unit with a dry, soft cloth. Avoid using cleaning agents or water. Check cables and connectors periodically for wear. The unit has no user-serviceable parts inside; for repairs contact qualified service personnel.
What is the maximum input level the N-8 DI can handle?
The maximum input level is +20 dBu. Higher levels may cause distortion. Use the pad switch to attenuate strong signals.
Can the N-8 DI be used with a battery?
No, the N-8 DI is designed to be powered exclusively by 48V phantom power. A battery power source is not supported. Ensure your mixer or interface supplies phantom power.
