TENSOR SERIES ACTIVE SUBWOOFER
1. INPUTS:
A
ccept balanced and non-blanaced Line level inputs signals compatible with XLRs. The balanced input provides
superior noise rejection when using balanced signals over long cable runs.
2. LINK OUT:
Output XLR's are hard wired to their corresponding
INPUT
XLR. These connections can be used to daisy chain
additional
TENSOR
cabinets.
3. CROSSOVER:
This controls the frequency range supplied to the onboard loudspeaker. It doesn’t have any effect on the signal
from the High Pass Output connectors.
5. POWER:
The LED illuminates when the unit it connected to a suitable mains source and the Power Switch is set to on.
4. CLIP:
The LED
will illuminate when a signal is approaching the clipping point. Reduce the Level/Gain control on connected
devices to prevent this. It is worth noting that a clipped signal, apart from sounding bad will not cause damage to the Power
amplifier because of the on-board limiter.
6. VOLUME:
Use to set the overall output level of the unit. This control does not have an effect on the audio level from the Left
and Right
HIGH PASS OUTPUTS
.
10. PHASE:
Use to provide a 180º phase shift at the loudspeaker output and can be used to correct phase problems when
multiple cabinets are used. Phase problems are evident in the form of reduced or lack of bass. The phase control does not effect
the
HIGH PASS OUTPUTS
.
8. GROUND LINK:
This will effectively disconnect the signal ground from the chassis ground and is useful for removing
potential earth loops. Earth loop problems can be detected by the presence of hum from the loudspeakers.
9. SHAPE:
The shape function changes the tonal character of the subwoofer. When Depressed, it provides a flat bass response,
but delivers a boost around 80Hz and punchy low end characteristic when engaged.
7. HIGH PASS OUTPUTS:
With a cut-off frequency of 95Hz the two balanced connections allow for additional full range
cabinets (such as the TRE-1201 or TRE-1501) to be added to the system. They are not suitable for connecting additional sub-
woofers. It is worth noting that the signals from the
INPUTS
to the
HIGH PASS OUTPUTS
are true Stereo and combined
with other cabinets allow for a stereo system. For more information, have a look at the sample setups on page 5.
REAR PANEL CONTROL: TRS-1500 and TRS-1800
