Audio System Description

Overview

The audio unit has a built in CD player. Audio units with navigation are referred to as audio-navigation unit. These units combine the audio system, the navigation system, and the CD/DVD player into one unit.

The audio unit acts as the processor for all audio functions. Select audio functions from the audio unit buttons or the audio remote switch (on the steering wheel). The center display provides the current audio status.

The audio unit has a built-in EEPROM (electrically erasable programmable read-only memory). This memory holds the audio presets (AM/FM radio frequency, sound settings, etc.) even when the battery is disconnected.

A security signal is daisy-chained between the audio and vehicle components for integration into the vehicle's security system.

There are two audio systems available for the Acura TSX:

- With navigation, it includes ELS audio system for surround sound with 10 speakers.
- Without navigation, it includes premium audio system with 7 speakers.










HDD Recording

The navigation system uses a HDD (hard disc drive) and can store music. To record music to the HDD, you must use an original CD or uncompressed CD-R files. The music must be loaded on a CD using the CD player. You cannot load music through the USB adapter or the auxiliary jack.

Song By VoiceTM (with navigation)

You can use the voice control to operate the audio system, including the Song By VoiceTM feature. See the Navigation Manual for more information.

Speed-Sensitive Volume Compensation (SVC)

All audio systems are equipped with speed-sensitive volume compensation (SVC). The audio-navigation unit or audio unit receives the vehicle speed pulse (VSP) from B-CAN. The system processes the speed input and increases the navigation or audio system volume level as the vehicle speed increases to compensate for the interior noise that occurs at higher speeds. When the vehicle slows down, the volume returns to its normal level. The SVC has four settings: SVC OFF, SVC LOW, SVC MID, and SVC HIGH that can be adjusted using the audio-navigation unit or audio unit. The factory default setting is SVC MID.

To change the audio unit SVC setting, press the MENU button to display the sound settings menu, then rotate the knob to adjust the SVC to the desired setting (SVC OFF, SVC LOW, SVC MID, or SVC HIGH).

To change the audio-navigation unit SVC setting, press the AUDIO button, and then select the Sound Setup from the AUDIO MENU on the navigation display. Rotate the interface dial to select the desired setting (SVC OFF, SVC LOW, SVC MID, SVC HIGH).

Telematics Muting Logic

The navigation system provides voice control for the audio, the XM, and the CD player. Voice control commands are communicated through the GA-Net (audio unit). When using the TALK/BACK buttons or route guidance (RG), the center speaker is muted and you hear the navigation instructions through the front speakers. When using the HFL/AcuraLink, the center speaker, the rear speakers, and the subwoofer are muted and the front speakers give the telephone sound. When using the HFL/AcuraLink and the RG (Route Guidance) or the TALK/BACK buttons, the rear speakers are muted and you hear the telephone sound and navigation instructions through the front speakers. Muting commands are passed on the GA-Net bus. For more information, see the navigation section. The outline of the audio interruption function is shown in the following table.
