Safety Warning
Warning
This Loudspeaker can produce high sound-levels. This may damage your ears permanently!

You can use the C7 a single-amp setup (one power amplifier for high- and low-frequency unit) or in a bi-amp setup (one power amplifier for the low-frequency-unit, one for the highfrequency unit).
If your setup is single-amp you must bridge the high- and low-frequency unit with a high quality speaker cable.

2. Setting up and Transport
2.1 Demands of speaker location
• Use the C7 in closed rooms only. Do not expose the speaker to high humidity, direct water and direct sunbeam.
• Take care of a minimum distance of 2 m of the speaker to monitors (TV, computer) and magnetic devices (audio/video-cassettes, floppy-disks, etc.).
WARNING
There may be a slight permanent imprint in soft floor-material.
2.2 Transport
Before any movement of the speaker switch of the power amplifiers and disconnect all cables of the C7 .
WARNING
Don`t try to move or transport the C7 alone! The weight affords at least two persons.

The high- and low-frequency unit can be connected as follows:
• single-wired: one cable-pair from power-amp to low-frequency unit, one cable-pair from low-frequency unit to high-frequency unit.
• bi-wired: one cable-pair from power amp to low-frequency unit, one from the power amp to high-frequency unit. This is recommended by ASCENDO.
• bi-amped: one cable-pair from separate amps for low- and high-frequency unit.
Take care of connecting always the plus (red) terminal of your power amp with the plus (4 +
6 / red) terminal of the speaker.
The conception of C7 utilizes a switch-able backfiring TOS-Unit. This Unit optimizes spectral inhomogeneous decay times.
The system offers two complementary modes of operation:
Switch (8) in position AN (Dipole)
• 4-way dipole diversity with TOS - Unit
Switch (8) in position AUS (Hemisphere)
• One-Point-Source with homogenous hemisphere diversity
Clean the enclosure and stand of the ASCENDO C7 with a dry and soft cloth.
Don’t use water or other chemicals. Don’t touch the tweeter and the woofer.
