Tannoy arena - Subwoofer Setup and Operation; Initial Setup Procedure; Fine-Tuning Bass and Crossover

SETTING UP
Ensure the main POWER switch is in the OFF position. Connect the subwoofer input socket to the sub out on your AV processor or amplifier, using a screened
phono cable. You can operate the subwoofers in two modes, AUTO and ON continuously, using the switch provided. In AUTO, the unit remains OFF until
an input signal is detected. Status is confirmed by the power light, which glows red in AUTO standby, but is otherwise green.
Firstly set GAIN volume to MIN, and LFE MODE switch to ON. This will bypass the unit’s internal crossover, with this function now provided for within the
AV processor. The XOVER FREQ. Control will no longer be functional. Set the PHASE control to 0
0
. The LED will turn green when switched ON, or when a signal is
detected in AUTO mode.
Set the LF EXTENSION control to mid position and play some music or other material through the system and slowly increase the input level control until roughly
the correct amount of bass is present. If this does not prove possible, rotate the PHASE control clockwise, which with some speakers and rooms will give increased
bass output. Moving the LF EXTENSION control anticlockwise towards the MUSIC position will give a deeper more extended bass, while moving it clockwise towards
the THEATRE position will increase the impact of movie sound effects. Fine adjustment of the controls will take a little time using a range of different programme material.
If an even bass performance and seamless transition to the satellites does not prove possible in your room, switch the LFE MODE switch to
OFF and experiment with the crossover frequency. It is often possible to reduce the influences of harmful room resonances in this manner.
AUTO POWER/ SLEEP FUNCTION
This subwoofer can be left permanently on in AUTO mode, under which conditions it will revert to ‘sleep’ mode after approximately
12 minutes. If not using your subwoofer for some time, switch OFF and remove the power cable from the mains outlet.
OVERLOAD PROTECTION
The Arena subwoofer is provided with circuitry to limit the maximum sound output, in order to eliminate audible distortion. This circuitry will normally operate
unnoticed. If however distortion is heard, this indicates the unit is being severely overloaded, and to avoid damage, the input level should be reduced immediately.
CLEANING
Dust the enclosure with a dry lint free cloth. Do not use any solvent-based chemicals.
