User manual INFINITY BASSLINK

[. . . ] It is important that all the speakers work together to reproduce frequencies they share. Depending on the orientation of the BassLink and the distance from it to the other speakers, the BassLink and the other speakers may be "in-phase" or "out-of-phase" The resulting conditions, known . as constructive and destructive interference, also play a role in shaping the frequency response of your system. Fortunately, BassLink has controls that may be adjusted to optimize both of these conditions. [. . . ] If your radio provides only speaker-level outputs, it may not have a remote wire. If you will be using the speakerlevel outputs from your head unit, you do not need to connect the remote output. The speakerlevel inputs will sense voltage on the speaker wires and the BassLink will turn itself on. If you are using only line-level (RCA) inputs, you must connect the remote wire to the BassLink. Note: BassLink is equipped with four line-level (RCA) inputs and four speaker-level inputs. Any combination of line-level and speaker-level inputs may be used to provide nonfading bass when connected to a head unit with four outputs. CONNECTING BASSLINK TO: Head units with dedicated subwoofer outputs (line-level): Connect the subwoofer output from the head unit to either the front or rear line-level inputs. Head units with four line-level (RCA) outputs: Connect the four line-level outputs to the four line-level inputs on BassLink. Head units with two line-level outputs and two (or four) speaker-level outputs: Connect the two line-level outputs from the head unit to either front or rear line-level inputs on BassLink. Connect two speaker-level outputs from the head unit to the Universal Interface inputs on BassLink, which correspond to the unused linelevel inputs. Head units with four speaker-level outputs: Connect the four speaker-level outputs from the head unit to the four Universal Interface inputs on BassLink. Head units with only two speaker-level outputs or two line-level outputs: Connect the two outputs to either front or rear inputs of corresponding type. Note: The Universal Interface input wiring harness included with BassLink is color coded to correspond with the speaker-level outputs of many aftermarket head units and adapters sold as accessories. Universal Interface color code: White: front left + White/black: front left ­ Gray: front right + Gray/black: front right ­ Green: rear left + Green/black: rear left ­ Violet: rear right + Violet/black: rear right ­ ­ RIGHT + REAR UNIVERSAL INTERFACE FRONT POWER-SUPPLY CONNECTIONS B+: Connect a wire (at least #12AWG) between the vehicle's + (positive) battery terminal and the "+BATT" terminal on BassLink. You must install a fuse holder with a 25A fuse within 18" of the battery. Route the power wire through a grommet in the vehicle's firewall. If there is no factory grommet available, you must install one. B­: Connect a wire (at least #12AWG) between the "GND" terminal on BassLink and a bare metal surface near the mounting location. You may need to scrape away some paint from the metal surface to insure a good connection. Use a screw and a lock (star) washer. TUNING BASSLINK BassLink provides several controls that simplify sonic integration with virtually any vehicle's unique acoustic properties. [. . . ] Power LED lit but no sound output: inputs not connected, head unit not functioning properly (no output), head-unit fader control set incorrectly (2-channel connection only). Output from BassLink sounds muddy or distorted: input gain set too high (servo LED lit constantly), bass boost set too high (servo LED lit constantly), head-unit output is distorted or blown. No output from BassLink when head-unit fader control set to front or rear (4-channel connection): input connections improperly wired.
