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

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.

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.

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signicantdelaybetweentheaudiosourceandthe

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.
