1.4 Operating modes

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.

4. Connection

5 Minus Outer Chassis (Coax) Mid / High
6 Plus Inner Chassis Low
7 Minus Inner Chassis Low
3 Switch TOS Unit / Dipole On - Off

6

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.

5. TOS-Unit

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 dive r s ity

6. Cleaning

Clean the enclosure and stand of the ASCENDO C7 with a dry and soft cloth.
Don’t use water or other chemical s . Don’t touc h t he tweeter and the woofer.
