Tortuga Audio Remote (legacy)

The Tortuga Audio Remote is a legacy product that is no longer offered for sale. It was shipped with the LDR1, LDR3, LDR6 and optionally with the LDR3x.V1 up until May 1, 2014 at which time it was replaced with the Apple Remote.

It’s highly unlikely that the Tortuga Audio Remote will work with any subsequent models other than those mentioned above. It is not supported by any current model.

The Tortuga Audio Remote is a custom 15 key infrared remote transmitter that uses the NEC IR protocol and is powered by 2 AA batteries.

The Tortuga Audio Remote has the following control functions:

Power: Toggles the LDRx power on if off, and off if on. 

Raise (Volume Control Mode): A brief press will raise the volume 1 step. Holding this button down will issue repeat commands and cause the volume setpoint to ramp up quickly. When the Volume is at maximum the Status LED will blink slowly.

Raise (Brightness Adjust Mode): When LDRx units with Numerical Displays are Muted, pressing Raise will increase the brightness of the display.

Lower (Volume Control Mode): A brief press will lower the volume 1 step. Holding this button down will issue repeat commands and cause the volume setpoint to ramp down quickly. When the Volume is at minimum the LDRx unit will Mute and the Status LED will blink slowly.

Lower (Brightness Adjust Mode): When LDRx units with Numerical Displays are Muted, pressing Lower will decrease the brightness of the display.

Mute: Mutes the LDRx if Un-Muted and Un-Mutes it if already Muted. When Mute is initiated, the LDRx volume will ramp down to zero and the Status LED will blink slowly. When Un-Mute is initiated, the LDRx volume will ramp up to its previous setting and the Status LED will be steady on.

Input Select (1-6): The Tortuga Audio Remote has 6 input select buttons labeled CD, DAC, Phono, TV, DVD  and Aux representing inputs 1-6 respectively. When an Input button is pressed, the LDRx unit will immediately Mute the unit and the Status LED will blink slowly. Once the desired Input has been selected, pressing the Enter key will lock in the selection, the Status LED will flash briefly and the unit will Un-Mute and ramp up to the same Volume setting as before but will now be connected to the newly selected Input.

 Balance: Pressing  the Balance button will put the LDRx unit into Balance Adjust Mode. The Status LED will blink rapidly indicated the unit is in Balance Adjust Mode.

 Left/Right (Balance Adjust Mode):  When in Balance Adjust Mode, pressing the Left key will incrementally shift the Balance towards the left channel while pressing the Right key will shift the Balance towards the Right channel. The Status LED will continue to blink rapidly. Once the desired Balance has been achieved, pressing the Enter key will lock in the Balance adjustment and the Status LED will flash briefly indicating the unit is now back in normal Volume Adjust Mode. Note that the Raise/Lower Volume keys remain operational during Balance Adjust Mode.

Reset (Balance Adjust): Pressing the Reset button to clear the Balance Adjust settings  to zero. The Status LED will flash briefly.

Infrared Protocol and Codes: The Tortuga Audio Remote uses the NEC infrared protocol. The specific codes used are listed below and can be easily programmed into most programmable remotes. Each command issued by the Tortuga Audio Remote is preceded by a System Code and followed by a Command Code.
