It automatically enters into standby mode when no input signal is detected for 25 minutes in order to save power while not in use. In addition, a highly efficient amplifier c cuitry design has been adopted to reduce energy consumption while the device is in use. 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.") Setup Example ■ When multiple speakers are connected to the two zones: (MODE: MONO) DCP (for zone A) Zone A: 15W x 6 = 90W BMG source DCP (for zone B) Zone B: 7.5W x 10 = 75W ■ When two-channel stereo is used: (MODE: STEREO) BMG source DCP 120W x 2 (two-channel stereo) Connections Attaching Euroblock Plugs Example (connection to the [REMOTE] connector) 1 Loosen 2 Approx. 5 mm 3 Slotted (approx. 0.2") screwdriver 4 Tighten Terminal screw Euroblock plug NOTE • You must use the supplied Euroblock plugs. If the plugs have been lost, please contact your Yamaha dealer. • To prepare the cable for attachment to a Euroblock connector, strip the wire as shown in the illustration using stranded wire to make connections. With a Euroblock connection, stranded wires may be prone to breakage because of metal fatigue due to the weight of the cable or due to vibration. When rack mounting your device, use a lacing bar when possible to bundle and fasten the cables. • Do not tin (solder) the exposed end. 1 Loosen terminal screws. 2 Insert cables. 3 Securely tighten terminal screws. 4 Insert the Euroblock plug into a terminal of this device. Connecting Speaker Cables 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. Caution • Ensure that load is not applied to the speaker cable. • This device uses a BTL (Balanced Transformer-Less) connection method for the amplifier output. As the amplifier output is sent to the positive and negative connectors, any contact with other terminals or the device chassis may lead to malfunction. NOTE Connect the cables so that the amplifier s "+" and "-" symbols match those of the speaker. If they are reversed, the phase will be reversed and the sound will not be output correctly. When using a spade lug Loosen the screw, insert the spade lug all the way from below, and tighten the screw. When using a bare conductor Loosen the screw, wrap the conductor wire around the barrier strip terminal, and tighten the screw. Be sure that the bare wire does not touch the chassis. Speaker cable ≥3.2mm (≥ 0.13") ≤5.8mm (≤0.23") 15mm* (0.6") * Actual size Wire should not touch the chassis.

Appendix High-Impedance and Low-Impedance Connections 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 High-Impedance Connections As long as the total nominal power input rating for all speakers is within the power output capability of the amplifie , any number of speaker systems can be connected in parallel. 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. Speaker transformer 70V/100V 10W 10W 10W 10W 10W Low-Impedance Connections When connecting multiple low-impedance speaker systems to a single channel, the following methods are possible. Parallel Connection When multiple speaker systems having the same impedance are connected in parallel, the total impedance becomes the individual speaker system impedance divided by the number of systems connected. 4Ω Cannot be connected 8Ω 8Ω 8Ω Total impedance = 4Ω Serial Connection When connected in series, the total impedance is simply the sum of the impedances of the speaker systems connected. However, if one speaker system happens to fail, the electrical signal will not be passed on and subsequent speaker systems will be affected. Interruption 4Ω Failure Total impedance = 8Ω 4Ω 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.
