Output Connections
It is not recommended that both the balanced and unbalanced
outputs of the Binloop be used simultaneously. Ground loops
(see section on Grounding and System Performance) and poor
high frequency response can result. Additional low frequency
accuracy can also be obtained by using 600 Ohm (low
impedance) interfaces on the Binloop outputs.
Compact Flash Media Reliability
Compact Flash MTBF (Mean-Time Between Failure) rates
published by most manufacturers are in excess of 1,000,000
hours under normal use. The fact is, properly installed Compact
Flash usage in the Binloop is a very benign environment for
Compact Flash media and there is a very, very rare occurrence
of failure.
When failures do occur they normally occur during the first few
hours of use. Often this is called “infant mortality.” Even this
failure mode is extremely rare, however.
Nonetheless, it is always prudent to properly backup all of the
audio and video data contained in your Binloop. This can easily
be done by simply copying the data to a PC hard drive or by
making CDR or Data-DVD/R backups.
Like any other computer system, your sound and video files for
the Binloop should be treated as critical data. Successful
operation of your installation depends on this data.
Removing a Card from the Cage
WARNING : The following information should only be used when
a card (Controller, or Video Reproducer) has failed and must be
returned to Alcorn McBride Inc. Removing a card carelessly
could result in further damage, which would not be covered
under your warranty.
PLEASE BE EXTREMELY CAREFUL!!!
1. Disconnect power from the unit.
2. Using a regular Phillips screwdriver, remove the screws
from the reproducer cover panel on the right side of the
Binloop front-panel.
3. Be careful of the display on the left cover. It has a cable
connected to it. Observe the polarity of this cable
connection and be sure to reconnect it in the same way
if it becomes disconnected.
