  • Page 8: About This Manual

    This document is intended to provide you with all the information necessary to properly install and integrate the SVS AS-EQ1 into your audio environment. After installing the Sub EQ GUI on your personal computer and properly attaching the AS-EQ1 to your Audio Video Receiver (AVR) or Preamp/Processor (Pre/Pro), you will be able to quickly step through a small number of tasks designed to equalize your subwoofer(s) in your listening environment.
  • Page 9 Installing the Sub EQ GUI on your PC To install the Sub EQ GUI on your computer system, insert the CD that came with your AS-EQ1 into your CD drive on the computer you will be using to configure the AS-EQ1. If the drive has been configured for “AutoRun”, the installer should automatically run.

    Connect your PC to the AS-EQ1 using the supplied USB cable, power on the AS-EQ1 using the on/off switch on the back panel, allow your PC to recognize the AS-EQ1, then start the Sub EQ GUI (note that if you start the Sub EQ GUI before connecting the AS-EQ1 via USB, Sub EQ will not recognize the AS-EQ1 is attached.

  • Page 14: Integrate The As-Eq1 With Your Auto Eq Receiver Or Pre/Pro

    If you use the Auto EQ feature of your AVR or Pre/Pro to EQ your listening environment, you MUST perform this step first. If you do not, your AVR or Pre/Pro and the AS-EQ1 will both apply EQ correction files to the subwoofer, which will result in poor subwoofer sound/performance.
  • Page 15 2. Take the Calibration Microphone from your AVR or Pre/Pro (NOT the Calibration Microphone from the AS-EQ1) and plug it into the Pass-through Mic In jack located on the front of the AS-EQ1. (see Fig. 12) 3. Locate the calibration microphone “patch cable” that came with your AS-EQ1 (1/8” mono male connectors on each end).
  • Page 16 The calibration of the Main/Satellite speakers are unaffected within the AVR or Pre/Pro using this process, and this insures only the AS-EQ1 will be handling the EQ of the subwoofers in actual system operation. 6. After completing the calibration of your AVR or Pre/Pro, remove its Calibration Microphone along with the calibration microphone patch cable from the AS-EQ1 and your AVR or Pre/Pro.

  • Page 18: Channel Configuration

    Dual discrete IN to dual discrete OUT represents “stereo bass” (two separate sources of bass). Alternatively, it can be used to connect two separate systems in the same room if you have that configuration. The AS-EQ1 will ping Subwoofer A, ping Subwoofer B, EQ Subwoofer A, then EQ Subwoofer B. It will not ping or EQ the combined A+ B.

  • Page 19: Level Matching

    Measurement task. 1. Insure the Gain on your subwoofer(s) plate amp is set to the middle of its range. 2. Set the Phase control of your subwoofer(s) to 0 (the AS-EQ1 will adjust each subwoofer to insure proper phase alignment).
  • Page 20 Calibrating the AS-EQ1 in Your Listening Environment 4. Attach the Calibration Microphone supplied with the AS-EQ1 to the Cal Mic Input on the front of the AS-EQ1. DO NOT use the microphone supplied with your AVR or Pre/Pro or any other Microphone as it may produce inaccurate results.
  • Page 21 (below) with a large number of measurement positions in order to avoid rework. If you are running more than two subwoofers (e.g. multiple subs attached to the AS-EQ1 Sub A or Sub B outputs) it is suggested you contact SVS Support for a discussion of properly Level Matching your specific configuration for your listening environment.

  • Page 23: Measuring Your Subwoofer(S)

    The AS-EQ1 measures the background noise level in the room before playing the test signal from each subwoofer. For the measurements to be valid the signal-to-noise ratio must be above a certain threshold and if it is not, the test signal from that subwoofer will repeat at a higher level.
  • Page 24 Calibrating the AS-EQ1 in Your Listening Environment 1. If you have not already done so, attach the Calibration Microphone included with the AS-EQ1 to the jack labeled Cal Mic Input on the front panel (behind the magnetically attached faceplate) of the AS-EQ1. DO NOT use the microphone supplied with your AVR or Pre/Pro or any other microphone as it may produce inaccurate results.

  • Page 25: Detection Results Entry Into Avr Or Pre/Pro

    NOTE : If your satellite speaker has useable extension and output at 40Hz, the AS-EQ1 may recommend it be set to LARGE (full range). SVS recommends that all speaker channels be set to SMALL for Home Theater applications unless the speaker(s) in question actually have clean/usable output down to 20Hz (which is very rare).
  • Page 26 The value reported represents the acoustical distance of the subwoofer, plus the electrical latency of the AS-EQ1. The distance reported will always be higher than the actual physical distance between the subwoofer(s) and the microphone location, and this is perfectly normal and not cause for concern.

  • Page 27: Save Results To As-Eq1

    Save Results to AS-EQ1 FIG. 18 The final task in setting up your AS-EQ1 is to save the results of your calibration to the device. WARNING - do not quit the Sub EQ application or disconnect the AS-EQ1 from your PC until the transfer is complete.
  • Page 28 Calibrating the AS-EQ1 in Your Listening Environment 1. By pressing the Transfer to AS-EQ1 button, the calibration file will be sent to the AS-EQ1 and allow you to listen to the non-EQ and EQ environment by selecting the Turn MultEQ On and Turn MultEQ Off buttons.
