EQs with Range Switch
complex program material as contained in stems or submixes and is ideally suited for mastering
purposes.
API’s 5500 also features a true hard-wire bypass which wires the output connector directly to
the input. Shortly after the power is first applied, or immediately after it is lost, a special circuit
enables “bypass mode” so that power thumps are never heard.
The 5500’s input XLR is connected to an active balanced circuit. The unit’s output XLR is driven
from a transformer coupled output and can drive any load from 600 ohms or more to full
output capability. There is no change from input to output in the unit’s polarity, so it is suitable
in studios using either pin 2 or pin 3 as the "hot" connection. Additionally, the 5500 has a 1/4
inch input connector that interrupts any present signal on the input XLR. It is balanced and can
be driven from either balanced or unbalanced sources. A positive signal on the tip will deliver a
positive signal on pin 2 of the output XLR. Using the 1/4 inch input does not bypass any internal
circuitry and does not change the gain or operating levels.
The 5500 features API’s industry exclusive five-year parts warranty and exhibits the reliability
and long life characteristic of all API products.
