Setup Instructions

General information tab for installing the interface.

Bluetooth Connection

Scan	Press this button to start the Bluetooth pairing process, then select the available device once it is found. “Connected” will appear in the top left corner of the app once paired.
Disconnect	Disconnects the interface from the app.

The ignition must be cycled on during this process.

Configuration

Identify	Click this button to confirm that the interface is connected properly. If it is, a chime will be heard from the front left speaker. (Only installations using the front left output white RCA jack.)
Reset to Defaults	Resets the interface to factory settings. During the reset process the amp(s) will shut off for 5-10 seconds.
Vehicle Type	Select the vehicle type from the drop down box, then click the apply button.
Equalizer (EQ) Type	User has the option of optimizing the vehicle’s sound quality with a Graphic or Parametric equalizer.
Lock Down	Click this button to save the selected settings. This must be done before closing the app or cycling the key otherwise all new changes will be lost!
Save Configuration	Saves the current configuration to the mobile device.
Recall Configuration	Recalls a configuration from the mobile device.
About	Displays information about the app, vehicle, interface, and mobile device.
Set Password	Assign a 4-digit password to lock the interface. If no password is desired, use “0000”. This will clear out any currently set password. It is not necessary to lock down the interface when setting a password.

A 4-digit only password must be chosen otherwise the interface will show “password not valid for this device”.

Outputs

Output Channels

Location	Location of speaker.
Group	Used to join channels together for simple equalization. Example, left front woofer/ midrange and left front tweeter will be considered simply left front. The letter M indicates the speaker assigned as the master speaker.
Invert	Will invert the phase of the speaker.
Mute	Will mute desired channel(s) in order to tune individual channels.

Crossover Adjust

Selecting High Pass and Low Pass will provide one crossover frequency adjustment. Selecting Band Pass will provide two crossover frequency adjustments: one for low pass, and one for high pass.

Select the desired crossover slope per channel, 12db, 24db, 36db, or 48db.

Select the desired crossover frequency per channel, 20hz to 20khz.

The front and rear channels default to a 100Hz high pass filter to keep the low frequency signals out. If a subwoofer is not being installed, change the front and rear crossover points down to 20Hz for a full range signal, or to the lowest frequency the speakers will play.

Equalizer Adjust

Graphic EQ

All channels can be adjusted independently within this tab with 31 bands of available equalization. It is best to tune this by using an RTA (Real Time Analyzer).

The Gain slider on the far left is for the channel selected.

Delay Adjust

Allows a delay of each channel. If a delay is desired, first measure the distance (in inches) from each speaker to the listening position, then enter those values to the corresponding speaker. Add (in inches) to the desired speaker to delay it.

Parametric Equalizer

Parametric EQ

Each output has a 5 Band parametric EQ per channel. Each band will give the user the ability to adjust: Q Factor Frequency Gain

The FLAT button above Filter #1 will reset all curves back to flat.

Inputs/Levels

Chime Volume	Allows the chime volume to be adjusted up or down.
Clipping Level	Use this feature to protect sensitive speakers like tweeters from being driven past their capabilities. If the output signal of the interface clips the audio will be reduced by 20dB. Turning down the stereo will allow the audio to come back at a normal level. The sensitivity of this feature can be adjusted to the listening preference of the user.
Amp Turn On	• Signal Sense - Will turn the amp(s) on when an audio signal is detected, and keep on for (10) seconds after the last signal. This ensures the amp(s) won’t shut off between tracks. • Always On - Will keep the amp(s) on as long as the ignition is cycled on. • Turn on Delay - Can be used to delay audio output to avoid turn-on pops.
Subwoofer Input	Select Front + Rear or Subwoofer input depending on preference.

Locking Down Data

You must lock down your configuration and cycle the key.
