3 Overview
The Kramer 900xl is a high-performance power amplifier for line-level
stereo audio signals. It accepts either a stereo audio signal on an RCA
connector or a stereo audio signal on a 3.5mm mini jack. It delivers a
speaker output of 10 watts RMS per channel into a 4Ω load on a 10A 4-pin
terminal block connector.
The 900xl includes:
Input selector buttons
Audio gain buttons for volume control
Overheating warning protection with LED indicator
A 12V DC power adapter
The 900xl is housed in a Kramer TOOLS enclosure.
To achieve the best performance:
Use only good quality connection cables
1
to avoid interference,
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight
coils
Avoid interference from neighboring electrical appliances that
may adversely influence signal quality
Position your Kramer 900xl away from moisture, excessive
sunlight and dust

- Used to address machines in a system via their machine numbers when several machines are controlled from a single serial port they are usually configured together with each machine having an individual machine number if the ovr bit is set then all machine numbers will accept implement the command and the addressed machine will reply for a single machine controlled via the serial port always set m4 m0 1 and make sure that the machine itself is configured as machine number 1 12
- When switching i e instruction codes 1 and 2 the input 7 bits is set as the input number which is to be switched similarly if switching is done via the machine s front panel then these bits are set with the input number which was switched for other operations these bits are defined according to the table 12
