NF-01A (Powered Near Field Studio Monitor)

Main features of NF-01A

• Ultra lossless design offers a natural crossover

between the woofer and tweeter.
A -6 dB/oct crossover network is used for the woofer,
while a -12 dB/oct network is used for the tweeter.

• The use of HP sound reflectors provides an ideal

internal sound processing means for elimination of
natural vibration developing within the speaker
enclosures.

• Power amplifiers capable of delivering 50W/50W

output are provided for the bi-amplifier driving
system for the woofer and tweeter.

• The low frequency filter switch and tweeter level

control are provided, allowing frequency response
compensation.

• The amplifier system is capable of accepting balanced

(XLR) or unbalanced (phone) input.

• By employing an HP diaphragm and dome tweeter, a

wide listening area that no other monitor system can
match is obtained.

1. Power LED

Lights when power is turned on.

2. Heat sink

<CAUTION>

Avoid contact with the heat sink.  Extended time of use
will result in a rise of temperature.

3. Loudness control

Adjusts output power.  Please refer to the descriptions given on
the next page for optimal use.

4. Tweeter level control

Adjusts tweeter level within a +/- 3dB range.  Please refer to the
description given on the next page for optimal use.

5. Low-frequency filter selector

Adjusts low frequency characteristics (around 55Hz range)
within a +/- 2dB range.  For detail, please refer to the next page.

6. Unbalanced input terminal (Phone jack)

Accepts -10dBV unbalanced input.

7. Balanced input terminal (XLR-3-31 type)

A4dBu balanced input (hot pin is #2).  Simultaneous
input from this terminal and the unbalanced terminal is not
possible.  Connection to the unbalanced terminal will defeat
the balanced terminal function.

8. Power switch

Turns power on.  make very sure the volume controls of
connected equipment are set to the null level.

9. AC IN connector

Accepts the AC cord provided.

• An HP diaphragm of a new type is used in the 13 cm

woofer.  Sound quality to low distortion and high
transition, which no other diaphragms can offer, has
become a reality.

• Anti - resonance is eliminated by the use of a UDR

tangential edge and push-pull damper in the woofer.
Also, substantial improvement is made in linearity, and
thus, accurate response to the subtlest sound signals
is realized.

• The tweeter employing a UFLC diaphragm (of soft dome

type), being most compliant to and reproducible of
even the subtlest signals, are of a wide range design
up to 40kHz.

• A highly rigid cast aluminum frame is used for both

woofer and tweeter.
This allows successful elimination of sound colorization
caused by undesired natural vibration.
