Rane RAP 10 - Manual

RAP 10
REMOTE AC POWER SUPPLY
OPERATORS MANUAL
GENERAL INSTRUCTIONS
Using the RAP 10 is as easy as it looks. Connect the red
outputs of the RAP 10 to the red input jacks on the products
to be powered using the supplied 6-wire modular connector
cables. The POWER switch controls all units powered from
the RAP 10. Power is applied immediately upon power switch
closure - there is no time delay power-up sequence.
MOUNTING THE RAP 10
Normally the RAP 10 is mounted below the Rane equip-
ment, and (better) toward the bottom of the rack. (Alterna-
tively, mount the RAP 10 at the very top of the rack, and
leave several blank spaces between it and other units.) This
allows sensitive mic level products to be mounted away from
the RAP 10 hum field. If there are any blank panels, always
locate them between audio equipment (or other hum sensitive
units) and the RAP 10 for the most hum-free performance.
Additionally, create as much ventilation space around the
RAP 10 as possible. This is not critical, it is just good
practice. When fully loaded, the RAP 10 requires unrestricted
airflow for proper cooling.
POWER SUPPLY CABLES
Each RAP 10 is shipped with (10) 6-wire modular plug
power supply cables. Additional power supply cables are
available from the factory or your dealer. Two lengths are
offered, either 24 inches (package of 4), or 6 feet (package of
3). Please specify a length when ordering.
CUSTOMIZING POWER SUPPLY CABLE LENGTHS
Rane makes available a Mod Cable Connector Kit for
customizing cable lengths for each installation. This kit
consists of a modular connector crimping tool (manufactured
by AMP, Inc.), plus (25) 6-pin modular connectors. Cutting
and crimping a new mod connector takes about 60 seconds.
6-wire cable and modular connectors must be used for all
interconnection. Common 4-wire cable and connectors will
not work. Do not substitute 4-wire for 6-wire cable and
connectors.
NOT ENOUGH CURRENT
Each output of the RAP 10 is rated for a continuous
current output of 650 mA. If more than 650 mA is required,
and you have an unused output, the issue of paralleling arises.
Paralleling of outputs is permitted with the RAP 10. A cute
trick that makes this easy is to use a 6-wir e wye-adapter (also
called T-connector, duplex jack, dual modular phone coupler,
etc.). Plug the single male end into the unit to be powered,
and run two 6-wir e cables from the duplex female side into
two channels of the RAP 10. This doubles the available
output current from 650 mA to 1.3 A.
TOO MUCH CURRENT
Sometimes you may be tempted to try and power two
units from one output of the RAP 10. If the total current
demand of both units is less than the 650 mA output current,
this daisychaining (running power out of one unit into
another) temptation becomes unbearable. In general, avoid
daisychaining of power supplie s
. Daisychaining of power
only works between units interconnected by fully balanced
technique s. There can be no signal ground connecting
daisychained units. Failure to follow this rule results in hum
due to an unbreakable ground loop caused by the common
power supply path. Life is simpler if you just say no.
RESETTING TIME
The RAP 10 is protected by solid-state current and
temperature sensing devices that reset automatically. This
automatic resetting takes approximately 15 minutes depend-
ing upon the nature of the overload. If power is lost on an
output, disconnect the power cable and wait at least 15
minutes before reconnecting the cabl e
. Meanwhile try to find
out why the unit demanded excessive current (Cable short?
Unit failed? Other?).
