MSB Technology Rev 1 (10 2012) user manual Front Panel Controls, Control Features

FRONT PANEL CONTROLS

Although the user interface is very simple and easy to use, there is one trick.

Input Button – Normally this switches inputs but if you hold the button, the DAC will be reset and will display the serial number and Firmware REV number on the display.

CONTROL FEATURES

MSB remote controls can be used to operate several MSB products. The top half is primary for the transport. The center is for the DAC and the lower part for the iLink. The Analog DAC has limited function depending on the interface you select. Features are activated as shown in the table below.

FEATURES		Advanced Remote
	Basic Remote		RS-232	Wi-Fi Interface
Power – Normally this button does nothing on the Analog DAC remote. The power button turns on and off the DAC IV Power
Base when the optional front controls have been installed. When the power base is linked to the Amplifiers and any other
MSB products, this button will turn off the entire system. (see DAC IV power base manual for details)
Volume up and down – The center block of the remote has several functions. The volume up and down buttons change the	•	•	•	•
system remote if the optional volume controls are installed in the DAC. dB of attenuation are shown on the DAC display.
The mute button instantly mutes the audio if the volume option is installed.
Input toggle– This feature toggles directly through the inputs of the Analog DAC even if the DAC is set to the auto mode.	•	•	•	•
Direct Input Select– Inputs can be directly selected and an input can be read to see if it is active.			•	•
Programming of remote user buttons 1, 2, 3 – These are user defined buttons. They can be programmed to execute any function			•	•
you wish from the following options.
#1 Phase Invert - Toggles phase invert on and off.
#2 Reclocking - Toggles reclocking on and off. This is especially useful for watching movies, where reclocking
may cause an objectionable audio delay.
#3 Display Off - Toggles the display on and off.
OPERATIONAL MENU OPTIONS
Phase Invert - Toggling the Phase Invert will change the absolute phase of the output. There are some recordings	•	•	•	•
that “accidentally” swap the phase. For those who are phase sensitive, we always include this option. The phase
of the outputs is inverted digitally.
Filter Select - This feature lets you select among a number of preloaded filters. There is not right or wrong filter			•	•
as the best filter depends on the original recording and the rest of the components in your system. We are always
working to develop new and better filters to compliment different system characteristics.
About - Displays information about the unit including the version number, serial number, distributor, and year of	•	•	•	•
manufacture.
SETUP MENU OPTIONS
Reclocking - This very important feature of the DAC allow all jitter to be removed from the input source. Data is		•	•	•
read into a memory and then independently read out using a ultra stable clock. When enabled this option will
completely replace the incoming clock with an ultra low jitter clock. The DSP monitors the incoming sample
frequency and detects standard sample rate signals, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, 192 kHz,
352.8 kHz and 384 kHz. The on-board clock then completely replaces the incoming clock. Other sampling
frequencies use the incoming clock from the source. The DSP allocates a huge internal FIFO buffer (1/2 second
at 44.1) that stores the incoming audio to decouple the incoming and outgoing data streams. Long absolute digital
silences in the music stream, such as between tracks and during pauses, are selectively shortened or lengthened
by the DSP to maintain data synchronization. This results in a significant delay between the audio source and the
analog audio. You will not normally notice this delay unless video is synchronized to the audio. For this reason
this feature may want to be turned off when watching video, or the video should be delayed. While using the
on-board clock some very long musical performances greater than one hour with no silences, pauses or track
skips may cause a buffer overflow when using a standard transport. This will sound like a small CD skip. You
will probably never encounter this case but if you do MSB can install a special ultra high accuracy clock in your
transport or other audio source to totally eliminate this possibility.
