Rear Panel Connections — Detailed Explanation

The SC-602 amplifier is equipped with both speaker-level and line-level inputs. Use the RCA/Phono type “INPUT” jacks when connecting from a pre-amp, signal processor, or line-level crossover. The “SPEAKER LEVEL INPUT” jacks connect directly to the speaker outputs of an integrated amplifier or receiver. Your amplifier section will notice no additional loading effects when you use these inputs because of their high impedance.

Note: Do not use both the RCA/Phono “INPUT” connections and “SPEAKER LEVEL INPUT” connections simultaneously.

ABOUT LOW - PASS CROSSOVERS

All of the SC-602 amplifier inputs sum the left and right channels together and the resulting signal is passed through an adjustable low-pass crossover before being amplified. The crossover control allows you to adjust the upper limit of the subwoofer’s frequency response from 30 to 160 Hz. The subwoofer’s response will begin rolling off above the frequency you set this control to. The slope is 24 dB/octave.

You should set the crossover frequency to obtain a smooth and seamless transition from the subwoofer to the main speakers in your system. If your main speakers are small with limited low frequency output, you may wish to choose a higher frequency (such as 100 -120 Hz) than you would with larger speakers which have greater low frequency output. The SC-602 amp’s crossover has a default of 80 Hz.

Most receivers and processors provide a menu option in which you can characterize main speakers as “large” or “small” speakers. This affects the bass signals passed to the main speakers. We recommend in most cases setting the main speakers to “small,” despite their size and frequency response characteristics, allowing all multi-channel bass and LFE signals to be passed to the SC-602. This is because the powerful 400 (x2) watt SC-602 amp combined with the SC-600 subwoofer are more likely suited to low bass reproduction than your amp and main speakers. With the burden of low frequency reproduction relieved, your speakers will exhibit better performance, and your overall system performance will improve.

Disabling the Low - Pass Cr ossover (Subwoofer Dir ect)

If your receiver/processors provides a crossed-over signal to the subwoofer you may want to bypass the SC-602 amp’s low-pass crossover. To do this, depress both the Crossover UP and Crossover DOWN buttons simultaneously. The numeric LED will show --indicating that the low-pass crossover has been defeated. To reactivate the low-pass crossover, simply push the Crossover UP or Crossover DOWN buttons.

A WORD ABOUT YOUR HOME THEATER RECEIVER’S CROSSOVER AND THE SC - 602 AMPLIFIER’S CROSSOVER

Your Velodyne SC-602 amplifier is designed to operate using the full range audio signal for input when using the built-in crossover. Many home theater processors/receivers have a “subwoofer out” jack that performs this same function and are designed to be used with a powered subwoofer.
