After turning the unit on, the power indicator will blink blue and no sound will be output for a few seconds. Wait until the indica- tor stops blinking and stays lit. o Since this unit has a large power transformer and capacitors, the power transformer might make noise for a short time after the unit is turned on. This is normal behavior, not a malfunction. B Power indicator This lights blue when the unit is on. A SOFTWARE maintenance port This is used for maintenance. Do not connect anything to this port unless instructed to do so by our service department. B LED brightness adjustment knob Use this to adjust the brightness of the power indicator. C TRIGGER connectors Use these connectors to control power from an external source. Do not connect anything to these connectors when not using them. D Input selection switch Use this to switch between the RCA, XLR and ESL-A inputs.

Do not change this when the unit is on. Doing so could result in a sudden loud noise that could harm your hearing or damage the connected speakers. E AUTO POWER SAVE switch Use this to turn the automatic power saving function on and off. When the automatic power saving function is on, if there is no audio input (continuous silence) from the selected input source for 30 minutes, the unit will enter standby mode automatically. o The input sources that are not selected have no effect on automatic power saving. F AC power inlet (~IN) Connect the supplied power cord to this AC inlet. After completing all other connections, plug the power plug into a power outlet.

Use only a genuine ESOTERIC power cord. Use of other power cords could result in fire or electric shock.

Disconnect the power plug from the outlet if you will not use the unit for a long time. G Holes for power cord support bracket screws Attach the power cord support bracket to these (page7). H SIGNAL GND grounding terminal Using commercially-available sheathed wire (for example, PVC- insulated) to create grounded connections with the speakers, the preamplifier or other equipment might improve the sound quality. o This is not a safety grounding terminal. I Analog input connectors Connect these to the analog output connectors of preamps. Set the input selection switch to choose the connector to use. Use commercially-available cables for connections. RCA: RCA cable XLR, ESL-A: balanced XLR cables Insert a balanced XLR plug until the connector lever locks. Press this lever and pull the plug out to disconnect. o The XLR connector is 2 “HOT”. Use a compatible cable. o Insert the plug completely. Do not bundle these cables together with power cords or speaker cables. Doing so could degrade the sound quality or cause noise.10 Connecting using ES-LINK Analog ES-LINK Analog overview The current transmission method utilizes the performance of HCLD buffer circuits that feature the ability to supply strong current at high speed. This suppresses the impact of impedance on signal paths, enabling pure and powerful transmission of signals. o Ordinary balanced cables (with XLR connectors) are used for connection. These connectors can only be used with compatible devices, however, because the transmission format is unique. Connecting to a preamplifier using ES-LINK Analog Preamplifier XLR cable XLR cable Analog audio output (ESL-A) connectors Use an XLR cable to connect the analog audio output (ESL-A) connector of a preamp to the ES-LINK Analog input (ESL-A) connector on this unit. o Set the input selection switch on this unit to ESL-A. o Normal XLR and RCA connections are also possible. Select the connection type that provides the audio quality you prefer. ATTENTION The ESL-A input connector of this unit is a male-type connector to prevent accidental connection by mistaking it for the XLR input connector.11 English

Precautions when making connections Complete all other connections before connecting power plugs to power outlets. Always disconnect the power plug of this unit before disconnecting anything else. Read the owner’s manuals of all devices that will be connected, and follow their instructions. Connections

Precautions when connecting speaker cables Connect the cables securely so that they do not become loose and the core wires or terminals at their ends do not become exposed and contact other metal parts or the unit.

Connect using a set of only one type. Preamplifier XLR cables XLR cables RCA cables Speaker (R) Speaker (L) Preamplifier that sup- ports ES-LINK Analog Select the audio input connector to be used. Select the audio input connector to be used. Included power cords c c Wall outlets12 Connecting speakers When using bare wires Loosen locknut B and insert the core wire in the hole. Then, tighten locknut B. o The hole for the insertion of the core wire is open vertically.Cross-sections o The maximum wire diameter that can be inserted is 4mm (5/32"). When using spade connectors Loosen locknut B and insert the spade connector. Then, tighten lock-nut B. o Use a spade connector with an inside diameter of at least 8mm (5/16").Terminal cross section8mm (5/16") or more Notes about speaker cables o Use commercially-available speaker cables to connect the speakers. o Use the shortest speaker cables possible. The longer the cable, the greater the resistance value and the more that damping perfor-mance is reduced. Moreover, length also increases inductance and capacitance, degrading the sound quality of high frequencies. o Use left and right speaker cables that have the same length. How to connect speaker cables Use commercially-available speaker cables to connect the + terminal of the unit to the + terminal of the speaker and the − terminal of the unit to the − terminal of the speaker. o Use speakers with at least 4Ω impedance. o If the exposed tip of the core wire of a speaker cable contacts another cord or terminal, a short could occur.Never allow a speaker cable to short. o Do not connect more than one amplifier to a speaker. o Do not bundle speaker cables with power cords. Doing so could cause noise.

The power plug should always be disconnected when connecting speaker cables. Locknut BLocknut A When using banana plugs Loosen locknut A and insert the plug into the opening in the end of the terminal. Then, tighten locknut A. o Keep locknut B tightened when using. o Carefully read the instructions for the banana plugs that you are using. Notice about the European model In accordance with European safety regulations, connecting banana plugs to speaker terminals is not allowed on European models.The holes into which banana plugs could be inserted have been covered with black caps. Connect speakers using bare wires or spade connectors. If a black cap should become separated from its terminal, return it to its original position.13 English Basic operation In order to protect the speakers, follow the steps below when turning on and off the system to which this unit is connected.
