Car e of your sub wo ofer

or cleaning so lu tions may cbmage the finish on the cabinet. We recommend us i ng a damp
cloth to cl ean the cab in et.
D uring no rmal conditions, your new subwoofer may be left on cominuously wi tho ut any
prob l ems. The un it is equipped with asigna l ·sensing [urn on/o ff [h at will automatically turn
on the unit wh en asi gna l is presem al the inputs and turn off the unit after severa l minutes
when th ere is no lo nge r any si gnal at the i nputs. If you pl an {Q leave the subwoofer unused
fo r an extended period of time, we recommend that you tum off the master power sw i tch

Troubleshooting & Service
If you s hould experience a prob le m with the operation of yo ur 5ubwoofer, plea se ch eck all
of th e fo ll ow i ng before see king service. Fo ll ow in g is a simp le troubles h ooti ng guide to
assist you.
1. Veri fy unit is plugged in and powe r out l et used is active.
2. Is powe r switch on?
3. Is autO tum on/off set properly?
4. Is un it receiving an input signa l from your source?
5. H ave a ll contro ls on subwoofcr (v olume, crossover , phase , CIC. ) been prope rl y set?
6. Is the mute on the remote comrol engaged?
7. Are bot h vo lum e controls properly set?
8. If un it has bee n running at high leve ls fo r an extended peJiod of ti me , one of the
protect i on ci rcuits may be engaged .
• Has the bui l t-in amp l ifi er overheated?
-Is your !XJwcr line voltage sagging under heavy use?
If the protection circu i try is acti \'c, the un it may cycle on and off until operating paramelers
return to n onnal. Proleaion drcuit op erat i on is usually i ndicated by a blinki ng power led.
Un de r more serious condit i ons, the un it may shut off complete l y. Nonnal operation will
return upon coo li ng, but you may be required to turn the power off and then on again to
reset the u ni t.
The follOWing cond it ion s require seIV i ce by a qua l ified (cchn i dan:
1. The power cord has become damaged.
2. The unit does nOt appear LO oper.lIe no r mally or exh ib it sa mar k ed change in
pe rform ance.
3. The unit h as been exposed 10 water.
4. Some pan of the cabine t or drc ui try isph ys i ca ll y damaged.
