Introducing the LINA Master Clock

The LINA Master Clock is an optional addition to your LINA system. While the LINA Network DAC and LINA Headphone Amplifier together deliver great performance, adding the LINA Master Clock improves the sound quality when using the network or USB inputs.
The LINA Master Clock generates word clock signals at 44.1 and 48 kHz, which have a very low jitter. After setting the LINA Network DAC to lock to a word clock, the LINA Network DAC automatically locks to the clock frequency that is an exact multiple of the incoming audio data. For example, if the incoming data rate is 192 kS/s, the LINA Network DAC selects the 48 kHz clock.
The LINA Master Clock cannot be used with source devices connected to the AES or SPDIF inputs on the LINA Network DAC, because there are no spare word clock outputs to connect an input to, such as a CD Transport. In these cases, select that input on the LINA Network DAC and use the Audio sync mode.

What’s in the box

Front

| Item| Description
---|---|---
1| Power button| To switch on or enter sleep mode, press briefly.
To switch off, press and hold until the status indicator turns off.
2| Status indicator| When in sleep mode, the status indicator is dim white.
When the unit is on, the status indicator is bright white.

Rear

| Item| Description
---|---|---

OUT 1| Word clock output 1. A 75Ω BNC connector, fixed at 44.1kHz.
Connects the unit to an audio device such as a DAC.
Word clock is only used for synchronisation and does not carry digital audio data.
3| WORDCLOCK
OUT 2| Word clock output 2. A 75Ω BNC connector, fixed at 48kHz.
Connects the unit to an audio device such as a DAC.
Word clock is only used for synchronisation and does not carry digital audio data.
4| Power socket,
fuse, and power switch| Power is connected via a standard IEC320 connector, with a power switch and a fuse holder.

Setting up

Connecting the LINA range
To connect the LINA Network DAC, LINA Master Clock and LINA Headphone Amplifier together:

Position the LINA range.
Connect the LINA Network DAC to the LINA Headphone Amplifier.
Connect the LINA Master Clock to the LINA Network DAC.

Positioning the LINA range
You can position the units in one of the following ways:

Place the units side by side.
Stack the units vertically in the following order:
LINA Headphone Amplifier at the bottom
LINA Master Clock in the middle
LINA Network DAC on top
To prevent overheating, we recommend that you leave some space around the units to allow for ventilation.

Connecting the LINA Network DAC to the LINA Headphone Amplifier
You can connect the LINA Network DAC to the LINA Headphone Amplifier using the balanced XLR sockets.

Using two balanced XLR cables, connect the BAL. LEFT and BAL. RIGHT outputs on the LINA Network DAC to the BAL. LEFT and BAL. RIGHT inputs on the LINA Headphone Amplifier.
On the LINA Headphone Amplifier, choose the unbuffered XLR input. If the status indicator is not white, press the Power/Input button until it changes to white.

Connecting the LINA Master Clock to the LINA Network DAC
You can lock the network and USB inputs on the LINA Network DAC to the LINA Master Clock.

Switch on the LINA Network DAC and the LINA Master Clock.
On the LINA Network DAC, choose the network or USB input.
Using two BNC cables, connect the WORDCLOCK output sockets on the LINA Master Clock to the WORDCLOCK input sockets on the LINA Network DAC.
Set the clocking sync mode on the LINA Network DAC to Auto.
The LINA Network DAC selects the appropriate clock input and locks to it.

If you lock an AES or SPDIF input on the LINA Network DAC to the LINA Master Clock, the source equipment will not be locked to the Clock, resulting in periodic clicks, dropouts or distortion.
To use the LINA Network DAC in this way, use source equipment that has a word clock input and a Master Clock with extra outputs.

Compliance and Safety

FCC compliance statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
You can determine whether this equipment is causing interference by turning it off. If the interference stops, it was probably caused by the equipment or a peripheral device.
If your equipment does cause interference to radio or television reception, try to correct the interference by one or more of the following measures:

Turn the television or radio antenna until the interference stops.
Move the equipment to one side or the other of the television or radio.
Move the equipment further way from the television or radio.
Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)
(USA only) If necessary, consult dCS Americas Inc. or an experienced radio / television technician for additional suggestions.

Changes or modifications not expressly approved by dCS Americas Inc.
could void the manufacturer’s warranty.
This product has demonstrated electromagnetic interference compliance under conditions that included the use of compliant peripheral devices and shielded cables between system components. In order to maintain compliance with FCC regulations, shielded cables (including Ethernet network cables) must be used with this equipment.
Operation with non-approved equipment or unshielded cables is likely to result in interference to radio and TV reception.

Do not install the unit near heat sources.
Use only the attachments and accessories specified by dCS.

CAUTION
To prevent the risk of electric shock and ensure the best audio performance, connect the unit to mains earth (ground) using the correct power cable.

A grounding type plug has two blades and a grounding prong, which is provided for safety. If the provided plug does not fit into your outlet, contact a qualified electrician.
Do not use the power cable if it is damaged.
If this unit is not being used for a long period of time, disconnect the unit from the power supply.
During lightning storms, disconnect the unit from the power supply to prevent power surges.

CAUTION
The safety covers on the unit protect you from electric shock.

Do not remove the safety covers from the unit.
If you do remove the safety covers from the unit, it invalidates the warranty.

If you want to use a mains regenerator with variable voltage and frequency, set the voltage to match your local voltage.
Set the frequency to either 50Hz or 60Hz.
Do not change the output voltage of the mains generator while it is connected to the unit.

NOTICE
If the unit is cold and is moved into a warm room, condensation may form inside the unit. Condensation may interfere with the normal operation of the unit. If the unit has been kept somewhere cold, remove all packaging and leave it for 1-2 hours before using it to allow it to reach room temperature.
