4.3 Back Panel Controls and

Connectors

Figure 4.3 below points out the controls and connectors on the back panel of the K Series amplifiers. The K1 and K2 look identical except for product nameplates and fuse specifications.

E. Bridge Output Switch

This switch selects whether or not the output signal is bridged across the two channels. To operate the amplifier in bridge-mono mode, set this switch to ON. To operate the amplifier in dual mode, set this switch to OFF. See Section 3.6.1 for more detail.

F. “Y” Input Switch

If you want to feed a mono audio signal to two channels, each with its own level control, set the “Y” Input switch to ON. This connects the

input signals of both channels together, in par- allel. To operate in dual mode, set this switch to OFF. See Section 3.6.1 for more detail.

G. XLR-type Input Connector

This is a female XLR-type connector, one per channel, that accepts a balanced or unbalanced input signal. See Section 3.4 for pin assign- ments.

H. Input Sensitivity Switch

This switch selects between 1.4V sensitivity or 26 dB gain. See Section 3.6.2 for more detail.

I. Phone Jack Input Connector

This is a 1/4-inch phone jack connector, one per channel, that accepts a balanced or unbal- anced input signal. See Section 3.4 for terminal assignments.

J. Power Fuse

This fuse protects the high-voltage power supply.

K. Power Cord

This permanently attached cable conducts the AC mains electricity to the amplifier.

L. Output Connectors

These 5-way binding-post connectors (one pair per channel) provide the amplifier output signal for connection to loudspeakers. The load can be connected in stereo (one load per channel) or in bridge mono (one load across the positive terminals of both channels). When using bridge-mono mode, be sure to set the Bridge Output switch to ON. See Sections 3.6.3 and 3.6.4 for details.
