250Hz

 and the factory default setting is 

60Hz

. See Section 11.5 

for further guidance on setting this parameter.

11.4.3 Invert

Invert 

switches (inverts) the acoustic phase (polarity) of the 

n-SUB

. Inverting phase can be of value when deciding on the 

optimum position for a sub-woofer. It is worth experimenting with 
phase inversion before ruling out a particular sub-woofer position 
for reasons of poor integration with the satellite speakers. The 
options are 

yes 

or 

no 

and the factory default setting is 

no

.

11.4.4 Input

Input 

selects one of the three 

n-SUB 

inputs described in Section 

11.2.1. The options are 

AV

,

 AMP 

or 

AUX 

and the factory default 

setting is 

AV

.

11.4.5 Lock

Lock mode prevents 

n-SUB

 parameters other than gain, mute 

and preset selection from being changed, thus ensuring that 
inadvertent adjustments are not made and that daisy-chained

n-SUB

 arrays remain synchronised. 

To lock a single 

n-SUB

 use the handset 

mode

5

 or 

mode

6

 

keys (control panel: 

mode

) to select lock followed by the 

handset 

up 

or 

down 

keys (control panel: 

up

 or 

down 

buttons) 

to select 

1

. When lock mode is active the lock indicator remains 

illuminated. 

Note:

 Settings cannot be adjusted from the control panel when lock 

mode is operational.

With multiple 

n-SUBs

, lock mode must be configured from the 

control panel for each 

n-SUB

 in turn. Use the control panel 

mode 

button to select 

lock

, followed by the 

up 

or 

down 

buttons 

to select a different lock number, from 

1

 to 

6

 for each 

n-SUB

.

Note:

 While there is no technical limit on the number of n-SUBs 

that can be daisy-chained, six is the recommended practical 
maximum.

Once an 

n-SUB

 has been allocated a lock number it can be 

temporarily unlocked for adjustment (and re-locked) by pressing 
and holding the appropriate handset 

numeric 

key (control panel: 

press and hold the 

mode 

button). The lock indicator will flash to 

indicate that it is temporarily unlocked. 

Note:

 Individual locking and unlocking enables subsequent 

adjustments to specific daisy-chained n-SUBs to be made without 
changing the settings of the other n-SUBs.

To permanently unlock an 

n-SUB

 it must first be temporarily 

unlocked, then the handset 

mode

5

 or 

mode

6

 keys (control 

panel: 

mode

) used to select 

lock

, followed by the handset 

up 

or 

down 

keys (control panel: 

up 

or 

down 

buttons) to select 

OFF

.

11.4.6 Label

A three character alpha-numeric display label can be defined for 
each 

n-SUB

 preset. Use the handset 

mode

5

or

mode

6

keys 

(control panel: 

mode

) to select 

label,

 followed by the handset 

mute 

key to select the character position and the 

up 

or 

down 

keys (control panel: 

up 

or 

down 

buttons) to select an alpha-

numeric character.

11.5 n-SUB Gain, Filter Frequency and Polarity

Setting 

n-SUB

 

gain

, filter (

freq

) and polarity (

invert

) parameters 

will require some careful listening and experimentation if 
optimum subjective performance is to be achieved. Try to put 
yourself in the position of the film sound designer or music mix 
engineer and aim for a sound that is consistent, well balanced 
and free of undue bass or midrange emphasis. It may be useful 
to listen with and without the 

n-SUB

 by using its 

mute 

function.

Note:

 Don’t use the mute function rapidly and repeatedly in order 

to judge the n-SUB’s contribution to the sound. Listen to a few 
minutes of material with the n-SUB operating and then repeat 
the same few minutes with it muted. Use a variety of programme 
material but make sure it has an adequate level of low bass.

11.5.1 AV System

When connected to an AV processor, such as the Naim AV2, 
the 

n-SUB

 

filter 

should always be set at its maximum - 

250Hz

This is because the processor’s sub-woofer (LFE) channel itself 
incorporates low pass filtering. 

n-SUB

 

gain 

should be set such 

that low frequency effects do not dominate but integrate within 
the context of the film. Only use the 

invert 

function if it proves 

difficult to achieve a satisfactory result through adjusting the 

gain

. If the 

invert 

function still results in no improvement, the

n-SUB

 should be moved to an alternative location in the room.

Note:

 Ensure that the processor’s “midnight” or “bass mix” 

functions are not operational when setting up the n-SUB.

Note:

 Different gain settings for music only and audio-visual 

programme material via an AV processor may be appropriate. Use 
the n-SUB’s preset feature to save appropriate settings.

11.5.2 n-SUB with n-SATS - Stereo Music System

For 

n-SUB 

integration with one pair of 

n-SATS

 in a conventional 

stereo audio system, initially set the 

filter 

to 

60Hz 

(the default 

value). Optimum 

n-SUB

 

gain 

will depend on the room acoustic 

and the position of the speakers within it. An 

n-SUB

 close to the 

listening position should, in theory, require less gain, however, 
if close to the listening position means the 

n-SUB

 is relatively 

distant from the walls, increased gain will likely be required. 
Aim to set the 

gain 

such that bass elements of the music are 

properly integrated. If bass subjectively draws attention to itself, 
the 

n-SUB

 gain is probably too high. Only use the 

n-SUB’

invert 

function if it proves difficult to achieve a satisfactory result 
through adjusting the 

gain

. If the 

invert 

function still results in 

no improvement the 

n-SUB

 should be moved to an alternative 

location in the room.

Once the 

gain 

is set, it may be worthwhile experimenting with 

small changes in 

filter frequency

 to fine tune the integration 

between 

n-SUB

 and 

n-SATS.

11.5.3 n-SUB with alternative speakers - Stereo Music 
System

Larger satellite loudspeakers than the 

n-SATS

 will most likely 

require the 

n-SUB

 

filter 

to be reduced. For medium sized stand-

mount loudspeakers begin with a setting of around 

50Hz

. For 

floor-stand loudspeakers initially set the 

filter 

to around 

40Hz

Gain 

and 

invert 

should be set as described above.
