1.4 Operating modes

You can use the C8-C 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.

2.1

Demands of speaker location

· Use the C8-C

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

The C8-C can be connected as follows:

· single-wired: one cable-pair from power-amp to outer chassis (4+5) unit, one bridge-
cable pair from outer chassis (4+5) to inner chassis (6+7).

· bi-wired: one cable-pair from power amp to outer chassis (4+5), one from the power
amp to inner chassis (6+7). This is recommended by ASCENDO.

· bi-amped: one cable-pair from separate amps outer chassis (4-5) and inner chassis (6+7)

Take care of connecting always the plus (red) terminal of your power amp with the plus (4 +
6 / red) terminal of the speaker.

5. TOS-Unit

The conception of C8-C 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

6. Cleaning

Clean the enclosure and stand of the ASCENDO C8-C with a dry and soft cloth.
Don’t use water or other chemicals. Don’t touch the tweeter and the woofer.
