Connect true to your system, give some playing hours to ‘’meet’’ each other with your system devices and finally enjoy the music. Because in the end this is the only thing we are looking for…
Before setting up your new true, we encourage you to read this manual thoroughly to properly acquaint yourself with its features. We love music and audio devices and we have built your new device with emotion and personal treatment.

Installation & Placement

True should be placed on a solid flat surface. You should avoid placing it near a heat source as this could compromise the performance and reliability. You should never place another component directly on top of this device. Make sure that true has an adequate flow of air around it.
Take care of the front panel’s glass blasting anodized finishing using a soft dry cloth. No need to use any sprays or polishes. Never use cleaners containing abrasives, as this will damage the surface.
Front Panel

In the front panel you will find the input selector knob (1) and the level attenuator knob (2).

You can select the desired input (3 positions)
You can adjust the desired level input

Rear Panel
In the rear panel you will find the connection inputs and outputs.
On the left side you will find the output to your power amplifier.
On the right side there are the three pairs of inputs.
The 3-position switch on the middle of the back panel gives you 3 choices about signal ground:
Position 1 Both channels keep common ground and both are connected to the chassis of True
Position 2 Channel A and Channel B keep separate ground to output A and B without connection to True chassis
Position 3 Both channels keep common ground to outputs without connection to True chassis
For the safety of your equipment
Make sure that all your equipment is turned off before any connection.
