7. Combo Input Jacks
Both channels of the iAMP offer actively balanced 'combination'
input jacks. These accept either 3-pin XLR or ¼" TRS connectors.
The design of the iAMP's circuitry allows for the highest possible
input signal level to be received from the majority of sources.
8. Channel Mode Switch
This switch allows the users to select from three operation
modes.
High Pass: This position will activate a high-pass filter on the
corresponding channel. This is a Linkwitz-Riley filter that will cut
all frequencies below 100 Hz. This is ideal for use when additional
subwoofer cabinets will be used in the setup, allowing the ampli-
fier to concentrate on signals above 100 Hz for use with mid-high
frequency speakers.
Full Range: This position will allow all frequencies to pass through
the amplifier; high, mid and low. This setting will typically be used
when full-range speakers are connected to the iAMP.
Subwoofer: Selecting this position on the Channel Mode Switch
will allow all frequencies below 100 Hz to pass through the ampli-
fier. Again, this is a Linkwitz-Riley filter. This position is ideal for
use with dedicated subwoofer speakers, allowing the amplifier to
concentrate on these frequencies and thus improving the level of
bass and your overall 'thump'.

9. Thru Output
These balanced ¼" outputs allow users to patch the incoming
signals directly out to additional amplifiers or input devices.
10. Speaker Connectors
The iAMP offers a professional-standard 4 pole speaker connector
for each output channel. Twist the cable clockwise to lock speakers
into place and counter clockwise to release.
11. Breaker Switch
In the unlikely event that an external influence posses an issue
that could potentially harm the unit, the iAMP's breaker will trip.
Check all wiring and cables before resetting a tripped breaker. If
the breaker trips again, it would be advisable to get in touch with
your country's Phonic distributor for repairs and services.
12. AC Power Connector
This input connector is for IEC power cables, allowing for AC power
to be sent to the unit. Please use the power cable provided with
the unit to power the iAMP. We strongly suggest that you under no
circumstances remove the grounding pin from the cable. Doing so
could be detrimental to the iAMP's operation and to your safety.
13. Cooling Fan
Due to the heat that can be accumulated when amplifying signals,
Phonic includes a variable-speed fan that is temperature sensitive
– activated and deactivating as necessary.
