1. Power Indicator

This light is bright when the subwoofer is on, and dim when the subwoofer is in standby mode.

2. Power Switch

Press the top of this rocker switch to turn on the subwoofer.

The subwoofer has an automatic signal-detection circuit. After approxi- mately fifteen minutes with no signal, the subwoofer will go into its quiet standby mode. The presence of an audio signal will turn it back on.

4. AC Line Fuse

The subwoofer is supplied with a conservative slow-blow type fuse to protect the electronics. If this fuse fails, replace it with the exact same type and current rating for your local AC voltage, as marked on the control panel near the fuse holder.

Note: Always unplug the power cord from your AC outlet before removing the fuse. To replace or inspect the fuse, use a small flat-

ended screwdriver to gently pry out the fuse carrier and fuse.

Normally you can leave the switch on, and let the subwoofer turn on when a signal is present, or off when it's not.

At night, or if you go out, or on vaca- tion, you can press the bottom of the power switch to turn the subwoofer off.

3. IEC Power Connector

The subwoofer comes with a detach- able linecord that attaches here. Make sure it is firmly pushed into place. Connect the other end to an AC outlet that is properly configured for the type of plug and has the correct voltage for your model.

5. Speaker-Level Inputs

If you are using a receiver which only has speaker-level outputs, you can connect it using the speaker-level inputs (see the hookup diagram on page 14). They can accept bare wire, banana, or dual-banana connectors.

If you experience excessive noise or hum using the line-level inputs, try us- ing the speaker-level inputs. This may lower the background noise level.

The Sunfire HRS series offers a range of high-performance subwoofers that cater to audiophiles and home theater enthusiasts alike. Among the notable models in this series are the HRS-12, HRS-10, and HRS-8, each delivering exceptional sound quality and powerful bass response.

The HRS-12 is the flagship model, featuring a 12-inch driver and a powerful 2000-watt peak amplifier. It utilizes Sunfire's patented High Pressure Drive technology, which allows for a remarkable output-to-size ratio. This means that despite its compact design, the HRS-12 can reproduce deep, driving bass that fills any room. The subwoofer also incorporates a unique dual opposing driver configuration, which minimizes distortion and enhances sound clarity by canceling out unwanted vibrations.

Next in the lineup, the HRS-10 features a slightly smaller 10-inch driver, but it still maintains impressive performance. With a 1200-watt peak amplifier, the HRS-10 is capable of producing rich, deep bass that complements movie action sequences or music performances. This model also benefits from the same High Pressure Drive technology, ensuring that users experience minimal distortion, even at high volume levels.

The HRS-8, with its 8-inch driver, is designed for those who desire quality sound in a more compact form factor. Despite its smaller size, this subwoofer is powered by a 600-watt peak amplifier and delivers surprisingly deep bass. Ideal for smaller rooms or setups that need discreet audio solutions, the HRS-8 still excels in performance, making it a favorite for apartment dwellers or those with limited space.

All models in the Sunfire HRS series incorporate advanced features such as adjustable phase control, variable crossover frequencies, and a front-firing design that allows for flexible placement options. This means users can fine-tune their listening experience according to their room's acoustics and personal preferences.

In summary, the Sunfire HRS-12, HRS-10, and HRS-8 subwoofers exemplify the brand’s commitment to delivering powerful, high-quality bass in a variety of formats to suit different needs. Whether in a home theater setup or a music listening environment, these subwoofers ensure a deep and immersive experience, making them standout choices in the marketplace.
