The power input rating is determined by the speaker systems and speaker transformers used. It is also possible to connect speaker systems that have different input power ratings. In the case of speaker systems that are capable of changing their input power rating (Yamaha VXC and VXS series, etc.), this can be utilized to vary the volume of each speaker. Ethernet straight cable (CAT5e or more; 800m or less (24AWG)) Euroblock DCP (for zone B) High-Impedance Connections The [SPEAKERS] output connectors on the rear panel are barrier strip type connectors. The connections are described below for two methods: using a spade lug and using a bare conductor. Warning DCP (for zone A) 4 RJ-45 Connecting External Devices Setup Example 3 1 For a high-impedance connection, a speaker transformer that raises the impedance to several hundred or thousand ohms is added to the speaker system. This allows the speaker system to be effectively driven with much lower current than is required for a low-impedance connection. Therefore, a large number of speaker systems can be connected. Even over long distances, there is very little transmission loss due to the cable resistance being negligible in relation to the impedance of the speaker system. High-impedance speaker connections usually operate at a specific maximum power amplifier voltage of 100 or 70 volt The more orthodox low-impedance connection does not use a speaker transformer. The speaker systems are directly connected to the power amplifier with a rated impedance generally a ound 4 - 16 ohms. For short distances over which cable resistance is insignificant, low-impedance connections deliver a sound quality that is superior to high-impedance connections. The differences between connection methods are explained as follows. ■ Multiple Speaker System Drive Capability Yamaha Digital Control Panel Insert the Euroblock plug into a terminal of this device. Auto-Standby and Auto-Wake Functions To reduce energy consumption, this device enters into standby mode when no input signal is detected for 25 minutes. It is also equipped with an auto-wake function that automatically turns the power on when an input signal is detected while in standby mode. Even when the device has been put into standby mode by the autostandby function, any microphone or BGM audio input will restore the power. The auto-wake function is turned on by default. The auto-wake function can be turned on or off by changing the rear panel [SETUP] DIP switch setting. (Refer to “Controls and Functions.”) 2 Securely tighten terminal screws. When using a spade lug This device complies with the ENERGY STAR international standard for energy efficient products.

Appendix Interruption 4Ω Failure Total impedance = 8Ω No sound Precautions for Rack Mounting This unit is rated for operation at ambient temperatures ranging from 0 to 40 degrees Celsius. When mounting the unit with other PA2120 unit(s) or other device(s) in an EIA standard equipment rack, internal temperatures can exceed the specified upper limit, esulting in impaired performance or failure. When rack mounting the unit, always observe the following requirements to avoid heat buildup: • When mounting the unit in a rack with devices such as power amplifiers that generate a significan amount of heat, leave more than 1U of space between the PA2120 and other equipment. Also either leave the open spaces uncovered or install appropriate ventilating panels to minimize the possibility of heat buildup. • To ensure sufficient ai flo , leave the rear of the rack open and position it at least 10 centimeters from walls or other surfaces. If the rear of the rack can’t be left open, install a commercially available fan or similar ventilating option to secure sufficient ai flo . If you’ve installed a fan kit, there may be cases in which closing the rear of the rack will produce a greater cooling effect. Refer to the rack and/or fan unit manual for details. NOTE • When the device is put into standby mode via the [REMOTE] connector, it is not possible to turn the power back PA2120 rear panel on by pressing the [z] button on the front panel, or by the auto-wake function with input signal detection. The power can only be turned on via the [REMOTE] connector. • When the device is put into mute mode via the [REMOTE] connector, the [z] button will flash in green.
