nEar04 connectors & functions
This text describes the layout and main functions of the front & rear panel
of our nEar04 active
1. TRS input - these jacks accept TRS input connections, either balanced
or unbalanced. For balanced connections, a 3-conductor TRS plug is necessary.
The TRS input is wired like this:
Unbalanced wiring works with either a 2- or 3-conductor TRS connector. A 2-conductor
TRS plug (or sometimes also just called TS plug) automatically grounds the minus
signal input, whereas a 3-conductor TRS plug wired unbalanced provides the option
of leaving the minus open or grounded. We recommend that you ground the unused
2. vent port -nEar04 is a vented box speaker system with a vent port
on the rear panel. Make sure you are not blocking the vent port (i.e. by putting
the speaker too close to a wall) or the sound colour will be changed.
3. speaker wire connection - use these connectors to connect the included
speaker wire with the second passive nEar04 speaker.
4. power switch - when you push the power switch, nEar04 will be turned
on, and -surprise- it will be turned off when you push the power switch again.
5. power port with ext. fuse - use this connector to plug in the detachable
3-circuit line cord that connects to the power outlet. 6. AC selection - you
can select either 110V or 230V AC power according to your local requirements.
Make sure this is selected properly before you switch on nEar04 for the first
time or your equipment could be damaged.
