Since all the audio connections are balanced, the convention of pin 2
or pin 3 ‘hot’ is of no consequence provided all connections are wired
in a similar manner.
Please refer to appendix B for details of the transformer balancing
options.
This switch, located on the rear panel, is the main grounding point for
all the MSR-604 II units connected to the system.
The switch will connect the electronic/signal ground to chassis earth
when in the ‘EARTHED’ position.
The switch will disconnect the electronic/signal ground from chassis
earth when in the ‘LIFTED’ position.
For a more detailed explanation of the grounding arrangements and
implications of this switch, please refer to section 4.2.
The LEDs are used to indicate that the power is turned on and present.
The LEDs are wired after the main DC Fuses, so should a fuse blow the
corresponding LED will go out. The DC fuses are on the rear panel and
are clearly marked with value and function. Always replace blown fuses
with the correct value.
The HEADROOM meter is calibrated to show signal level relative to the
clip point. In practice, the red 0db LED will illuminate when the signal
is approximately 0.5dB below actual clip. The meter indication is not
affected by HEADPHONE LEVEL control.
Adjusts the level of the headphone amplifier from off to full level.
Because the amplifier is designed to produce high monitoring levels into
any impedance headphones extreme caution must be used when setting
headphone levels.
CAUTION! ALWAYS TURN LEVEL DOWN BEFORE LISTENING TO
UNKNOWN SIGNALS. HIGH EFFICIENCY HEADPHONES AND A
HOT SIGNAL CAN PRODUCE DANGEROUS SOUND PRESSURE
LEVELS. OBSERVE THE WARNING SYMBOL NEXT TO THE
HEADPHONE SOCKET.
The gain of the monitor system is such that the amplifier will not clip
or distort even if the level control is turned fully up. This ensures that
if any distortion or clipping is heard it is not due to the monitoring
system and needs to be corrected at the signal source or by adjusting
the channel gain settings.
