Frequently Asked Questions - Prima APSP G7 AUDISON
How do I connect the Audison Prima APSP G7 to my car stereo?
Connect the high-level inputs to your speaker outputs or use the low-level RCA inputs. Ensure proper grounding and use quality cables to avoid noise.
What is the optimal input voltage setting?
Set the input sensitivity to match your head unit's output voltage. Start at a low level and increase until you hear distortion, then back off slightly.
Can I use the APSP G7 with a factory radio?
Yes, the high-level inputs accept the amplified signal from factory radios. The auto turn-on feature detects signal and powers on automatically.
How do I set the crossover frequencies?
Use the crossover controls to set high-pass and low-pass filters according to your speaker types. For example, set high-pass around 80 Hz for mid-woofers.
What does the remote control do?
The remote control lets you adjust volume and subwoofer level from the front seat. It connects to the processor with a dedicated cable.
How do I troubleshoot no sound output?
Check power, ground, and input connections. Verify the turn-on signal and ensure the mute/standby mode isn't active. Also check the fuse.
What are the power supply requirements?
The device operates on 12V DC with a negative ground. A solid ground connection is essential for proper operation and noise suppression.
How do I perform a factory reset?
Press and hold the reset button on the unit for 5 seconds with the power off. All settings will return to default.
Can I bridge channels for more power?
No, the APSP G7 is a signal processor, not an amplifier. It does not deliver power to speakers; it prepares the signal for external amplifiers.
Where is the best place to mount the device?
Mount it in a dry, well-ventilated location such as under the seat or in the trunk. Keep it away from heat sources and moving parts.
