the control ring will bring up the current input. Additional presses right or left will change the 

input. The changes take effect immediately. Pressing the center of the control ring toggles 

between the Volume and Input displays. 

The up and down buttons on the control ring change the volume. 

The Menu button toggles mute on or off. This button works when either the Volume or 

Input display is up.   “MUTE” will only appear if the user is on the the volume screen. It will 

not be visible when the Input display is up.

A long press of the Menu button (more than 2 seconds) enters the menus. 

By default, the unit comes up at volume 25. However, if the user has Fixed Volume set, the 

unit will come up at that volume. 

Inputs can be selected from either the DirectStream MK2 front panel display or the included 

remote control.

From the front panel display controller, press either the right arrow to scroll forward through 

the inputs or the left arrow to scroll in the opposite direction. Pressing the control's center 

button returns you to the volume control menu.

Input Names is a sub-menu inside the Audio Input sub-menu. This feature allows you to 

customize the name shown for each input. For example, Input 1 is I

2

S 1. If you are using 

the PS Audio AirLens or SACD Transport on this input, you can select that name. You can 

enter the Input Names sub-menu the same way as other sub-menus, by double pressing 

the menu button or by pressing the center button on the control ring.

When you enter this sub-menu, you will be guided through the process of selecting new 

input names.
