INTRODUCTION

Following the design of the NFP-1/2 it became apparent there was a need for a more economical monitor style speaker to be designed suitable for less demanding applications.
The new design uses a PORTED cabinet to help with the bass response, this involved some serious consideration, In this type of arrangement the port area is set by the cone area of the bass speaker, if the Port area is smaller than recommended air noises are produced, the dilemma and compromise comes from the fact that the length of the port required to tune the cabinet to a required frequency is set by the area of the port. Not surprisingly it is not uncommon to find that the required length will not fit inside the cabinet, the usual solution to this is to make the area of the port less which reduces its length and increases noise. We chose a different approach by making the port exit through the base of the cabinet, a detachable section completes the port and makes a stand for the speaker to sit on.
This novel idea also means that the speaker can be used as a sealed enclosure by simply placing it on a flat surface without the stand or used as a ported cabinet by placing it on the stand.

REAR PANEL FACILITIES
FULLY BALANCED INPUTS – Choose from balanced 1/4” Jack or XLR input to connect up your speaker to your audio source (i.e.. audio interface etc.)
INPUT SELECT SWITCH – Select which input source you are using, 1/4” Jack or XLR input.
VOLUME KNOB – Use to set the gain of the individual speaker. If using as a pair we recommend setting both to the same level. Start at 12 o’clock and adjust up and down until desired level is reached, bear in mind the size of the room you are set up in and adjust accordingly.
REAR PANEL TOP:

GROUND LIFT SWITCH – Use this to reduce or eliminate ground-related noise arising from ground loops in audio cables if you experience any unwanted noise.
RCA IN – Use to connect to an audio source when using an RCA cable.
LINE IN – This 1/4” jack socket is used to connect the output of line level devices.
POWER SWITCH – Use to power the speaker on.
MAINS INPUT – Use the included mains power lead to plug into a 240v mains socket.
