The LOC2SL converts high-level speaker signals to low-level RCA outputs for amplifier integration. This guide covers installation and troubleshooting.
The Audison LOC2SL is a sophisticated line output converter that extracts low-level preamplifier signals from high-level speaker outputs without requiring head unit modification. The device implements analog signal processing to reduce speaker-level voltages (20-50V RMS) to line-level outputs (200-500mV RMS) suitable for amplifier inputs. Input impedance circuits prevent loading of factory amplifier outputs. Differential signal processing rejects common-mode noise generated by alternators and ignition systems. Active filtering minimizes distortion while maintaining full frequency response. Gain adjustment via remote signal controls allows volume management from driver location. Each channel operates independently with isolated circuit paths preventing crosstalk between front and rear channels. Power supply uses a capacitive input circuit for noise reduction and transient stability. Thermal protection circuits prevent damage from continuous overload conditions. The LOC2SL connects to factory speaker outputs at the amplifier or speaker location using twisted pair shielded cable. Proper grounding through the vehicle chassis prevents potential imbalances. Remote control wiring provides variable gain adjustment without adding complexity. Placement away from ignition and power distribution prevents electromagnetic interference. Shielded cable routing follows manufacturer recommendations to minimize induced noise. Configuration adjustments match individual amplifier input sensitivity and source material characteristics.

Frequently asked questions
Where should I locate the LOC2SL converter?
Place near the amplifier location within the vehicle, away from power distribution. Use shielded cable for long runs to prevent noise coupling.
How do I identify factory speaker output wires?
Refer to vehicle-specific wiring diagrams. Speaker wires typically come in pairs with twisted configuration at the amplifier connector.
What is proper gain structure setting?
Set LOC2SL output level so amplifier inputs reach 80% maximum without clipping at normal listening volume.
Can I use unshielded speaker cable instead of shielded?
Not recommended for long distances. Factory EMI will couple into unshielded lines causing noise and distortion.
What causes intermittent output or noise with the LOC2SL?
Loose speaker connections, corroded terminals, or inadequate grounding. Verify all connections and use star-point ground technique.
