TANNOY iwSA 500
5.0 INSTALLATION
5.1 Mounting
The amplifier is two rack units high (2U) and will fit into a standard EIA 19” rack. Amplifiers should not be stacked directly on top of each other, we recommend a space at least 3” for the top and sides with 5” on the back . When shelf mounted the height of the supplied feet is adequate.
5.2 Operating Voltage
WARNING!
A label just above the mains cable connector on the rear of the amplifier indicates the AC mains voltage for which the amplifier is wired. Connect the power cable only to the AC source referred to on the label. The warranty will not cover damage caused by connecting to the wrong type of AC mains.
6.0 CONNECTIONS
6.1 Input Connections
From an unbalanced source the hot (+) center conductor connects to the center pin of the RCA connector. The

6.2 Connecting The Speaker
Speaker connections are made via 4 gold plated binding posts. When connecting 1 subwoofer to the amplifier the (+) wire connects to the RED
(+) binding post of output #1. The
When connecting 2 Tannoy subwoofers one will connect to output #1. Negative
Never connect either output terminal to ground or to some other output or input terminal. Pay attention to speaker polarity; loudspeakers connected out of polarity degrade sound quality, and may be damaged as a consequence.
6.3 Cable Choice
Always use the best quality of cable available within your budget. High quality audio signals passing from the amplifier to the loudspeaker are unusual in their demands on the cable. Wide dynamic range and frequency bandwidth information has to coexist with the ability to transmit peak currents of at least 10 Amps, without incurring any loss or signal impairment. This explains why the sound quality of the information reproduced by the loudspeakers is so dependant on the physical properties of the cables connecting them to the amplifier.
Technically, we recommend
Keep the speaker cable leads as short as possible. Do not use shielded leads, such as microphone or guitar cable. Remember that the speaker cable robs the power of the amplifiers in two ways: by increasing the load impedance and by introducing resistive power losses.
7.0 OPERATION
7.1 Operation Precautions
•Make sure that the power switch is set to “off” before connecting any input or output, or operating the switch on the rear panel.
•Make sure that the AC mains voltage is correct, and the same as the one printed on the rear panel of the amplifier.
• Make sure that the switch on the rear panel for limiter function is in the correct position. | 7 |
