LINE VOLTAGE
The 915 | Preamplifier | is | supplied in either a 17” Black Version, | or a | 19” Silver Version. | The | 19 | ||||
model has rackmounting | holes provided | for installation in | equipment | racks. | The holes | are | on | ||||
standard | EIA spacings. |
|
|
|
|
|
|
|
| ||
The | 915 | produces | very | little heat during operation, and therefore requires no special consider- | |||||||
ations | for | ventilation. The preamplifier | should be located | at | least | several | inches away | from |
components that contain large power transformers (such as power amplifiers), due to the
possibility | of audible | hum or | buzz from magnetic | radiation. |
|
| |
The | 915 | Preamplifier | is configurable for either 100 - | 120 volt, or 200 - | 240 | volt operation. This | |
is | accomplished by | changing | internal jumpers on | the printed circuit | board. | The procedure is |
detailed in the section “CHANGING LINE VOLTAGE RATING”. Make sure that the unit is configured for your local AC line voltage before attempted use. The configuration is labelled directly above the power cord connector.
OPERATION/CONNECTIONS
POWER CORD CONNECTION
INITIAL POWER- UP/MUTING SYSTEM
Units | wired | VACare | supplied | without power cords. Local agents will supply cords with |
male | connectors appropriate to | the local | standard. |
Units wired for
connector plugs into the receptacle | provided on the rear panel. This power | cord | is | a standard | ||||
IEC Type 320, | Should | replacement ever be necessary, | be | sure to | ||||
replace it with an identical cord. |
|
|
|
|
|
|
| |
Never remove the grounding pin from | the male end | of the cord. In applications | where | a | grounded | |||
wall | outlet is not available, a ground | adaptor should be employed, with the ground tab or wire of | ||||||
the | adaptor connected to a suitable | earth | ground. |

For units wired for
Preamplifier’s circuitry. If desired, this switch may be left “on” at all times to allow circuits to be thermally stabilized for maximum fidelity as soon as the system is used.
