Signature 2.0

System Installation

The Signature 2.0 is a powerful audio controller that delivers high-quality sound in a variety of multichannel modes from a wide range of input sources. Although many aspects of the 2.0 resemble familiar audio components, the flexibility and range of control the 2.0 offers means that some steps in the installation process may be a bit different from traditional analog-only audio products. For that reason, it is important that you read the following section carefully even if you are familiar with audio systems.

As a safety note, it is always good practice to make certain that the 2.0 and all equipment being installed and connected to it be turned off and unplugged from AC-power sources. This prevents the possibility of accidentally sending any audio or control signals through the system that may damage your equipment.

We also recommend that you use high-quality cables when making connections to external audio and video equipment. There are many brands of cables to choose from, and we suggest that you consult with your dealer to select the cables that suit your needs and budget.

After unpacking the unit, and placing it on a solid surface capable of supporting the weight, you will need to make the connections to your audio and video equipment. The following steps need to be done only when the 2.0 is first installed, or when a change is made to the input source equipment.

Input Connections

Unlike traditional audio/video products, which have fixed source inputs assigned to specific products or sources (e.g., “VCR” or “CD”), the Signature 2.0 allows you to connect inputs from a variety of audio and video sources, and then assign them to custom tailored source “profiles” as you desire. The following instructions will guide you to making the individual connections, while the actual assignment of the sources is explained in the section of this manual covering the Sources Menu on page 27.

When making audio/video connections it is a good idea to note the connection points on the User Worksheet provided in Appendix B.

For simple installations, connect your audio and video sources according to the chart on page 6.

Audio Inputs

The 2.0 accepts inputs from conventional analog audio products and both coaxial digital and optical digital audio sources. The flexibility of the 2.0’s profile system allows you to connect both analog and digital outputs from the same source (such as DVD, a laser disc player or a Digital Television adapter) and then associate that source with any video input or source name.

In addition, the 2.0 will decode PCM digital signals, Dolby Digital (AC-3*) data and DTS. PCM digital is used by conventional CD players or the standard digital output of a laser disc player, while Dolby Digital is used by DVD players as well as high-definition television sets (HDTV), many new computer games and other future digital audio devices. DTS is another digital audio format, used for both audio-only discs as well as DVDs and laser discs. When a digital source is selected, the 2.0 will automatically test the digital data. If the surround mode in use is not compatible with the digital data input, the mode name will flash in the front panel Information Display (see figure FPD-12 on page 40) alerting you to the error. Pressing the Display button xwill give you an alternate mode selection.

Audio input connections are made in conventional left/right pairs to the Analog Audio Inputs ª and either optical or coax connections to Optical or Coax Digital Audio Inputs à ¡. When making connections, be certain to note the equipment connected to each input using the chart in Appendix B.

IMPORTANT NOTE: Do not make connections from the “RF” output of a laser disc player directly to the 2.0. The RF signal must first be demodulated by an optional, external device, which is then connected to the 2.0 via a datastream digital connection. Improper connections to an RF digital source may result in damage to your equipment.
