VT 2507 Power 25 Watt Background Music Pager Zoning Amp
VT 2503 Amplifer
The 2507 is a 25 watt background music amplifier with the built-in capability to
supply adjustable levels of power output to three separate locations. As such it
is an economical alternative to the typical zoning amplifier which utilizes three
separate amplifiers and output transformers.
This zoning amplifier features a high performance transistor power amplifier
with a total output capability of 25 watts that can be divided into three
70 volt line loads. If, for instance you wish to divide the power to three zones
with a maximum of 8 watts per zone, then the wattage settings per speaker
transformer should total 8 watts for that zone. That power level would of course
correspond to the maximum setting of that zone’s level control. The output
could also be split into 10 + 10 + 5 watts with the correct wattage settings per
zone, and so on.
Output protection for this amplifier consists of current limiting, transient
suppression diodes and AC fuse.
The pre-amplifier section features feedback type bass and treble controls. Input
capability of the basic unit provides for unbalanced medium level program input
with a front panel gain control and a rear panel sensitivity control. Incremental
level controls are provided for each of the three zones.
Condition: Used. Power on test only
