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. Use a commercially-available BNC coaxial cable with 50Ω or 75Ω impedance for each connector. At Esoteric, we use Esoteric MEXCEL stressfree cables for reference. For detailed information, access the following website. http://www.esoteric.jp/products/esoteric/accessory/indexe.html10 Basic operation

1 Press the POWER button to turn the unit on. The power indicator lights blue. o When the power is turned on, the unit starts warming the crystal oscillator (OCXO) up to its operating temperature. It takes two minutes for the oscillator frequency to stabilize.

When you do not plan to use the unit for an extended amount of time, turn the preheat (PrHEAT) setting OFF and press the POWER button to turn the unit off. 2 Make clock output settings. When using the CLOCK OUT connectors

1) Set the clock reference frequency to 44.1 or 48kHz.

Press the MENU button to open the FREQ menu and use the A and B buttons to set the frequency mode (pages 14–15). 44 (44.1kHz) Use for playback of CDs, Super Audio CDs and other 44.1kHz sources.48 (48kHz)Use for playback of DVDs, DATs and other 48kHz sources. (Some DVDs and DATs are recorded at 44.1kHz. In this case, use the 44.1kHz setting.) o When using only universal clock (100kHz or 10 MHz), either setting is fine. o Only use 44EXP or 48EXP for frequencies that are not cov- ered by the 44 and 48 modes (page 15).

2) Use the A and B buttons to set the frequencies

sent to connected devices (page 11). When setting 10MHz OUT connectors Press the 10MHz button to turn output on and off. Use the menu to set which 10MHz OUT connectors (1–4) to use (page 16). o If you do nothing for five or more seconds, setting mode will end and ordinary display will resume. (If DISP is set to SHORT, this will happen after three seconds.) 3 On the connected devices, turn clock sync ON (or set to slave mode). Read the owner’s manual for each device for instructions on how to set their clock sync status properly.If you connect this unit to devices from other manufacturers, be sure to read the manuals of those devices to confirm the clock frequencies that they can receive.Some devices require the clock frequency to be set to the same value as the audio signal sampling frequency.Some dual AES connections might require that the clock fre-quency be set to half of the audio signal frequency. o Due to the nature of the crystal oscillator (OCXO), continuous operation stabilizes the precision of operation, so we recommend turning the preheat (PrHEAT) setting ON (page 16). o Settings are retained even when the power is turned off. o Once settings have been made, those settings can be used when the power is turned on again.Set the frequency mode according to the type of disc to be played or device being used (page 15).11 English Clock output frequency setting You can set the clock frequency output from the CLOCK OUT connectors. o This unit has 2 pairs (A and B) of clock outputs that can be sepa- rated further into 4 individual outputs (A1, A2, B1 and B2). You can set the clock frequency independently for each of these outputs. o By default, the A and B outputs are set to be used as pairs. Setting A and B outputs by pair (default) When you change the A setting, the output frequency is set for both A1 and A2 simultaneously. Follow the same procedure for B. When “A >” or “B >” appears, pressing the A or B button changes the output frequency of that pair. Press repeatedly to cycle through the options. o Press and hold the A or B button for at least two seconds to set A2 or B2, respectively (See “Setting A2 or B2”). o If you do nothing for ten or more seconds, setting mode will end and ordinary display will resume. (If DISP is set to SHORT, this will happen after three seconds.) Setting A1, A2, B1 or B2 Press the A button for at least two seconds until “A2>” appears. Then, press the A button to change the A2 setting. You can set different clock frequencies for A1 and A2. Follow the same procedure for B. Setting A1 or B1 When A2 is set to any value that is not the same as the A1 setting, when “A1>” appears, press the A button to change just the A1 out- put frequency. Follow the same procedure for B. Setting A2 or B2 Press the A or B button for at least two seconds to set A2 or B2. When “A2>” appears, press the A button to change just the A2 out- put frequency. Follow the same procedure for B. o To set A1 after setting A2, press the A button again after return- ing to the ordinary display. o If you set A2 to the same value as A1, “A” will appear again, and you can set the output frequency used by both outputs in the A pair simultaneously. Follow the same procedure for B (See “Setting A and B outputs by pair (default)”).12 When the frequency mode (FREQ) is set to 48: OFF No clock signal is output. 48kHz 48kHz clock frequency is output. 96kHz 2 × 48kHz (96kHz) clock is output. 192kHz 4 × 48kHz (192kHz) clock is output. 24.5MHz 512 × 48kHz (24.576MHz) clock is output. 100kHz 100kHz clock is output. 10MHz 10MHz clock is output. A2 = A1 The A2 clock output matches the A1 clock output and will be switched with the A1 setting. This only appears for the A2 clock setting. B2 = B1 This setting for B functions in the same way as the “A2 = A1” setting. Frequency setting options The frequency setting options depend on the frequency mode (FREQ) setting (page 15). When the frequency mode (FREQ) is set to 44: OFF No clock signal is output. 44.1k 44.1kHz clock frequency is output. 88.2k 2 × 44.1kHz (88.2kHz) clock is output. 176.4k 4 × 44.1kHz (176.4kHz) clock is output. 22.5MHz 512 × 44.1kHz (22.5792MHz) clock is output. 100kHz 100kHz clock is output. 10MHz 10MHz clock is output.

OFF The POWER button turns the crystal oscillator (OCXO) on/off with the unit.

This turns the power for the crystal oscillator (OCXO) on regardless of the POWER button setting. This shortens the amount of time until the oscillator stabilizes after the unit is turned on. o When the unit power is off, clock is not output even though the crystal oscillator (OCXO) is operating. o If the crystal oscillator (OCXO) is always on, the unit will con- sume considerably more power when the unit is off. Reference clock setting MCK>*** OCXO The built-in crystal oscillator (OCXO) is used for the reference clock.

Setting mode (continued)17 English Messages PLL LCKING The 10 MHz reference clock from the built-in crystal oscillator (OCXO) or the reference frequency input (EXT IN) connector is being locked by the internal PLL circuit. When locking completes, this message will disappear. o Ordinarily, only a few seconds are needed until locking com- pletes (PLL locking time), but it can take up to a minute depending on the operating temperature and other factors. o If locking cannot be completed because input conditions are not met when set to EXT10M, the message will continue to be displayed. Check the input reference clock specifications. NO 10M-IN! This appears when the reference clock is set to EXT10M and no 10MHz reference clock signal is being input to the reference fre- quency input (EXT IN) connector. Check the input reference clock. When not using an external clock source, set it to OCXO (page 16). Maintenance Use a soft dry cloth to wipe the surface of the unit clean. For stubborn smudges, use a damp cloth that has been thoroughly wrung out to remove excess moisture.

For safety, disconnect the power plug from the outlet before cleaning. o Never spray liquid directly on this unit. o Do not use chemically-treated wipes, thinner or similar substances because they could damage the surface of the unit. o Avoid allowing rubber or plastic materials to touch the unit for long periods of time because they could damage the cabinet.18 Troubleshooting If you experience a problem with this unit, please take a moment to review the following information before requesting service.
