User manual CAMBRIDGE SOUNDWORKS BASSCUBE 8S

[. . . ] ACCESSORIES ­ Do not place the subwoofer on an unstable cart, stand, tripod, bracket, or table. The subwoofer may fall, causing serious injury to a child or adult and serious damage to the product. VENTILATION ­ Slots, openings and metal fins in the cabinet are provided for ventilation, to ensure reliable operation of the subwoofer and to prevent it from overheating. These areas must not be blocked or covered such as by placing the product on a bed, sofa, very deep pile rug, or other similar surface. [. . . ] OUT TO SPEAKERS Connect your left and right speakers to these outputs if you use the SPEAKER LEVEL INPUTS. 7. LOW PASS FREQUENCY When you connect a BassCube to the Subwoofer Out of a 5. 1 channel Dolby Digital® or DTS® audio system, set this control at its full clockwise rotation. If you connect a BassCube with speaker wires, or to the Subwoofer Out of a stereo receiver, adjust this control higher for small main speakers and lower for large main speakers (see page 13). 6. PHASE (BassCube 10S only) The main speakers and the subwoofer may cancel each other out across the small range of frequencies where they overlap. This control will counteract this effect. 4 1 2 6 3 7 * SET LOW PASS FREQ HERE SPEAKER LEVEL INPUTS + R L + AUTO OFF ON 3 2 1 SUBWOOFER LEVEL 5 4 6 7 8 9 0 10 LINE LEVEL INPUTS WHEN USING 5. 1 CHANNEL HOME THEATER SUB OUT PHASE 0° 180° LOW PASS FREQUENCY (Hz) 100 85 120 L R POWER RED ­ STANDBY GREEN ­ ON MONO + R L + 75 140 * OUT TO SPEAKERS BassCube 10S Back Panel Diagram 5 8 7 CONNECTIONS About your audio components: You can connect a BassCube to a receiver, an integrated amplifier, a preamplifier/power amplifier combination, or other audio component. For brevity, this manual will refer only to a "receiver, " but the instructions will also apply to any audio component. You can use a line level signal output from one of these components (like a subwoofer output) or speaker level outputs, but not both types of outputs simultaneously. Always set the BassCube's power switch to OFF before making any connections. LINE LEVEL INPUTS Subwoofer Out RECEIVER OR DECODER Line Level Connection You need a signal cable for this type of connection, usually with an RCA plug at both ends. Connect the BassCube as described below: Dolby Digital (or DTS) receiver: Connect a mono signal cable from the RCA jack labeled Subwoofer Out (or possibly LFE or just SUB) on the receiver to the BassCube's R (mono) LINE LEVEL INPUT. Set the LOW PASS FREQUENCY control to it's full clockwise setting. Dolby Surround® or Stereo receiver with subwoofer output: Connect a mono signal cable from the RCA jack labeled Subwoofer Out (or possibly just SUB) on the receiver to the BassCube's R (mono) LINE LEVEL INPUT. Preamplifier/power amplifier: If your preamplifier has a pair of unused volume-controlled signal outputs, use a stereo signal cable with RCA jacks at both ends to connect it to the BassCube's LINE LEVEL INPUTS. Otherwise, use two "Y" adapters (Cambridge SoundWorks A1Y1M2FY, one RCA plug to two RCA jacks or equivalent) as shown in the diagram to create an additional pair of signal outputs to connect your BassCube. LINE LEVEL INPUTS Y-adapters R Mono L PREAMP OUTPUTS TO POWER AMP L R To power amp (Front amp in surround system) Stereo signal cables R Mono L POWERED SUBWOOFER 8 Speaker Level Connection Connect speaker wire from the receiver's left and right speaker outputs (the main or front connectors) as shown in the diagram. Connect speaker wire from the BassCube's OUT TO SPEAKERS connectors to your left and right speakers. Note: When you activate the Subwoofer Out jack on a Dolby Digital audio system, bass signals to the main speakers are automatically filtered out. This is a feature of a Dolby Digital decoder's bass management system. How much bass is filtered out of the main speakers depends on the Dolby Digital settings. If too much bass is filtered out, your audio system will have weak output in the frequency range where your subwoofer and main speakers overlap. This frequency range is often referred to as "midbass. " If you suspect your system has weak midbass output, first make sure your subwoofer's LOW PASS FREQUENCY control is set at its full clockwise rotation. Then check your audio system to see if its Dolby Digital decoder has a "crossover" or "high-pass" frequency adjustment for the main speakers. Unfortunately, there may not be an adjustment on your audio system's Dolby Digital decoder for main speaker bass (other than small or large), or it may be hard to hear any improvement. In this case, you can insure accurate midbass output by inactivating the Subwoofer Out jack of your Dolby Digital audio system. [. . . ] Avoid placing the BassCube on a wet or damp carpet. Final Adjustment Note: Use a variety of your favorite program material (video or audio) when adjusting the subwoofer output. Once you arrive at the best setting, leave the SUBWOOFER LEVEL control at that setting. Use your audio system tone controls to make temporary bass output adjustments. We hope you enjoy the new sonic dimensions your BassCube subwoofer reveals to you. Fuse Replacement 1. [. . . ]
