INSTALLATION

WARNING:

• Be sure to install it in a safe place from which it cannot fall or tip over.
• Do not connect loudspeaker wires or other high voltage sources to the inputs.
• Do not short-circuit the outputs.
• Do not allow the chassis to touch any metal parts, such as the frame of an equipment rack. This might create a parallel ground path that could degrade the sound of your system.

Placement

The unpacked devices can be placed one by one on the shelves of a stable rack eider side by side, or can be laid directly over each other: Line Block ON Power Block.

Install the Preamplifier chassis as close as possible to associated audio components to keep interconnecting cables as short as possible.

Adjusting feet

The Line & Power Blocks are equipped with adjustable feet. After placing the units to the desired place, it is possible to precisely adjust the horizontal position by rotating the front feet. This is especially important at Power Block, because there is hanging transformer and should not have nothing to touch. A supportive bubble level is enclosed.

Connecting the DC Supply and Control cables

DC Volt. Connectors: These connectors provide DC power from the Power Block chassis to the Line Block chassis. Use the two supplied Multi-pin "DC VOLT. INPUT/OUTPUT" cables to connect Left / Right DC Volt. Output to the Left / Right DC. Volt Input.

Using the supplied Multi-pin "SUPPLY / CONTROL" cable, connect the Power Block's SUPPLY / CONTROL connector to the Line Block's SUPPLY / CONTROL connector.

The upper position of the connectors is indicated by the triangle ( ) for easier orientation.

Connecting the Line Input / Output Cables

Connect the left channel output of a source to the desired left channel input number of the Line Block unit and do the same for right channel.

You can use single ended RCA or balanced XLR cable for the connection.

Connect the left channel output of the Line Block unit to the left channel input of the power amplifier or to the left monoblock. Do the same for right channel.

You can use single ended RCA or balanced XLR cable for the connections.

For the best sound performance, we recommend to use a balanced XLR cables, coming from the balanced outputs on the source device to your Line Block and for connection to the Power Amplifier as well.

Note: To release the XLR connectors press on the release button next to the XLR socket, and pull the XLR plug out at the same time. Do not pull on the cable, only on the plug.

Connecting Turntable (Phono Input)

Connect the twin RCA cable from your turntable to the Phono input, white for left channel, red for right. Turntables normally includes a single wire earth lead. Use the Chassis Ground connector to connect this lead. Unscrew the terminal to expose the hole, which will accept the lead. After insertion, tighten the terminal to secure the lead.

Select your phono cartridge system (MC/MM) and other appropriate options in the Phono settings menu.

System Remote Control (REM)

The Line Block is equipped as standard with an RJ45 plug for system remote control.

If you own the Block Audio's Mono Block, using the two supplied "REM" Cables, connect the REM Left and REM Right to the left and right Mono Block.

Connecting AC mains Cable

If everything is connected, plug all three mains cables from a wall outlet or Power distributor to the AC Mains Input sockets.

Appropriate AC mains version (115 V/60 Hz or 230 V/50 Hz) is factory pre-configured and is marked on the back panel close to the AC mains sockets.

The device connector of enclosed mains cord is equipped with V-Lock system. This may prevent accidental disconnection. To release the device mains connector, press on the yellow release button and pull the plug out at the same time.

For best performance, try to route the power cord away from signal cables.

VOL. OFFSET: This option allows you to match the volume of your headphones with the speaker volume in the system.

SURFACE CLEANING

The cabinet outside is coated with a special paint that is resistant to spotting. However, from time to time you may wish to clean the surface of your Block Audio equipment to remove dust, or any material build up from the atmosphere or from common use. Therefore, we recommend only gently clean the dust off, eventually wiping the water moistening microfiber cleaning cloth while observing the following guidelines:

• As a safety precaution, always unplug the unit from the wall outlet before cleaning
• Always use a cloth that is soft and clean
- Never use abrasives or polishing compounds anywhere on the unit
- Never apply liquid directly to the surface of the unit
• Use the cloth dry or with mild surface cleaners of either liquid or foaming type
- Apply only small amounts of cleaner to the cloth
- DO NOT rub the surface but wipe clean only. Excessive rubbing may wear the coating or screen printed text.
