14 - Specifications, etc.
This section provides technical details relating to the
TM-D4000.
All specifications are given with the factory reference
level of –16 dBFS. This can be changed to either
–20 dBFS or –9 dBFS by a qualified service person,
affecting the maximum output level (0 dBFS)
Changes in specifications and features may be made
without notice or obligation.
