2.1 Quick Start

This quick start chart summarizes the basic setup and operation steps.

Overview

3 Overview

The Kramer 905 is a high-performance power amplifier for line-level stereo

audio signals. It accepts either a stereo audio signal on an RCA connector or

a balanced stereo audio signal on a terminal block connector. It delivers a

speaker output of 80 watts RMS per channel into a 4Ωload on a 10A 4-pin

terminal block connector.

The 905 features:

•Two input selector buttons

•Two buttons for adjusting the volume and a mute button

•An unbalanced stereo input on RCA connectors and a balanced

stereo input on a terminal block

•An RS-232 port

Control your 905:

•Directly, via the front panel push buttons

•By RS-232 serial commands transmitted by a touch screen system,

PC, or other serial controller

The 905 is housed in a 19” 1U enclosure and is powered by a universal AC

power supply.

To achieve the best performance:

•Use only good quality connection cables1

•Avoid interference from neighboring electrical appliances that may

adversely influence signal quality and position your Kramer 905

away from moisture, excessive sunlight and dust

to avoid interference,

deterioration in signal quality due to poor matching, and elevated

noise levels (often associated with low quality cables).

To connect the 905, as illustrated in the example in Figure 2, do the following:

1. Connect an unbalanced stereo audio source (for example, the unbalanced

output of the DVD 1 player) to the L and R INPUT 1 RCA connectors.

2. Connect a balanced stereo audio source (for example, the balanced stereo

audio output of the DVD 2 player) to the INPUT 2 terminal block

connector.

3. Connect the OUTPUT terminal block to a pair of loudspeakers:

Connect the “L+” and the “L-” terminal block connectors to the left

loudspeaker, and the “R+” and the “R-” terminal block connectors to the

right loudspeaker. Do not ground the loudspeakers.

4. Connect the power cord to the power socket and connect the cord to the

mains electricity (not shown in Figure 2).
