Level, Crossover Frequency, By-Pass Switch

Level

Since your subwoofer is designed to work in conjunction with other speakers, a level control is provided that will allow you to balance the output of the subwoofer with the rest of your speakers. Once set, the level control should not require further adjustment. Begin with the level control at minimum position. Slowly increase the level clockwise until the subwoofer's output is equal to that of your other speakers.

Note:

Output level is relative and can be different from location to location . Always return to the normal listening location to evaluate any setting changes.

Crossover Frequency

The crossover frequency control is used to adjust the point at which the subwoofer stops reproducing the frequencies played by the other speakers in your system. Most home speakers will reproduce some bass signal, but depending on their specific type and size, the subwoofer enhances the lower frequency response of your system. The control is adjustable from 50Hz (very low cutoff) to 180Hz (high cutoff). Frequencies higher than the cut-off frequency will not be reproduced by the subwoofer. Raising the crossover setting increases the mid-bass frequencies that the subwoofer will reproduce. Lowering the crossover will do the opposite. We recom- mend starting at the 10 o'clock position and adjusting based on your speakers. Larger speakers will reproduce more of the lower frequencies, and you may set the crossover to below 100Hz. Smaller home speakers won't produce as much of the lower frequencies and the crossover may be set above the 100Hz setting. The higher the crossover frequency the more midrange bass will be reproduced. Only the lowest bass tones will be reproduced as the crossover frequency is reduced. If the receiver or source component is a Dolby DigitalTM unit, the ideal crossover setting may be around 100Hz. If the audio source is a THXTM rated device an optimal crossover setting may be around 80Hz.

Note: Bass is relative to the overall output of a speaker system and is subjective to the listener's ear. Set the crossover frequencies to a level that sounds pleasing to your ear and the overall reproduction of your audio.

By-Pass Switch

The by-pass switch is set depending on which type of input source will be used. When using the High Level Input the by-pass switch should be set to the "OFF" position. This will allow use of the crossover control to determine the frequency of the subwoofer output. When the Line Level Input (also described as RCA in) is being used, the type of input source must be determined prior to setting the by-pass switch. The by-pass switch should be set to the "ON" position only if a dedicated subwoofer output or LFE output is used. The "ON" position of the by-pass switch will disable the internal crossover. If a non-LFE or non-dedicated subwoofer output is used for the Line Level Input, the bypass switch should be set to the "OFF" position to allow proper use of the crossover control.

Connecting the AST SUB10S

General Information

Signals input to your subwoofer will first pass through the crossover. The portion of the signal below the current crossover frequency setting will be reproduced by the subwoofer. The unprocessed signal will also be passed to the High Level outputs.

High Level Input

These inputs are designed to accept a full band amplified signal from the speaker outputs of a receiver, power amp, or other device not equipped with line level outputs. Connect the speaker wires from the output of the amplified audio source via standard speaker wire to the inputs of the High Level Input.

High Level Output

The original amplified signal from your audio source is present at these outputs when using the High Level Input as the audio source. Connect speaker wires from the High Level Output (never more than one wire per terminal connection) to a pair of audio speakers.

Low Level Input

These RCA jacks are designed to accept a dedicated subwoofer output, a LFE line level signal, or a standard line level signal from a receiver, pre-amp, surround sound decoder or similar device. When using a single line level output from an audio source, connection to either the Left or Right input is sufficient. If your audio component has line level stereo outputs then connect both RCA line level outputs to the Left and Right Low level Input.
