Installation

Positioning the unit

<Place the Logo speaker unit on a level, firm surface, avoiding direct sunlight and sources of heat or damp.

<Do not place Logo in an enclosed space such as a bookcase or closed cabinet unless there is good provision for ventilation.The Logo speaker unit is designed to run warm during normal operation.

<Do not place your record deck on top of Logo. Record decks are very sensitive to the noise generated by mains power supplies which will be heard as a background ‘hum’ if the record deck is too close.Vibrations from Logo may also cause the pickup stylus to jump tracks.

Power

Logo is supplied with a moulded mains plug already fitted to the lead. Check that the plug supplied fits your supply – should you require a new mains lead, please contact your Arcam dealer. Logo is fitted with a transformer designed to accept nominal mains voltages from 100V to 240V.

Push the IEC plug end of the power cable into the socket on the back of Logo, making sure that it is pushed in firmly. Plug the other end of the cable into your mains socket and, if necessary, switch the socket on.

Logo is fitted with a main power switch on the rear panel, above the power inlet: make sure that this is switched on to use Logo.

If your Logo is not to be used for a prolonged period, switch the unit off at the main power switch.

Indicator LED

An indicator LED is positioned across the top edge of Logo’s cabinet.

When the indicator LED is off, it indicates that the speaker is completely disconnected from the mains. A blue

light from the indicator shows that the speaker is powered up and ready for immediate use. A red light from the indicator shows that the speaker is in standby (power-saving) mode and will power up as soon as an audio signal is received.

Standby switch

AUTO MANUAL	The push-in Standby switch provides two
	settings: Auto and Manual.

STANDBY ‘Auto’ (button out) switches Logo’s amplifier to standby after a period of

idleness (about 15 minutes) when no audio signal has been received.‘Manual’ (button in) means that Logo’s amplifier is on whenever the unit is receiving mains power.

Interconnect cables

We recommend the use of high-quality screened audio interconnect cables. Poor quality cables will degrade the performance of your system. All cables should be kept as short as is practically possible.

It is good practice when connecting your equipment to make sure that the mains power-supply cabling is kept as far away as possible from your audio cables. Failure to do so may result in unwanted noise in the audio signals.

Note: When connecting Logo to signal leads, or when moving Logo to a new position, make sure that the unit is not receiving power by switching off and disconnecting the power lead.

Connecting to a sound source

Check that your sound processor/receiver is switched off before connecting Logo. Failure to do this may result in both speaker and amplifier damage.

If your sound source has a Pre-out sub or LFE Out output, connect this to IN LFE on the back panel using RCA (phono) connectors at each end. If your sound source does not have a SUB or LFE output, connect the left and right channels of the stereo pre-amp

output (Pre out L and Pre out R) to IN L and IN R,

respectively.

You may connect both the LFE and the L and R outputs to Logo if you wish to use both the LFE channel and to supplement the bass response of ‘Large’ Left and Right speakers.

Out L, Out R and OUT LFE provide line-level outputs for ‘daisy-chaining’ further units, in a multi-room installation, for example.

After connecting

Turn the sound source amplifier volume down to minimum before switching on. Switch the source amplifier on, select a source signal, then gradually increase the volume to the required listening level.

Care of your speaker

Running-in

In the same way as a new car requires a ‘running-in’ period, so do all loudspeakers.Your Logo may sound good when you first connect it, but with time it will improve dramatically. Expect about 50 hours use before the full potential of your Logo is realised.

Cleaning

To clean your speaker simply use a soft, slightly dampened cloth to wipe off any dust or dirt. Do not use solvent-based or chemical cleaning products as these may damage the finish of the speaker cabinet.

Power handling

Arcam speakers are designed to reproduce recorded music under normal domestic conditions.We do not recommend nor warrant them for commercial applications, such as discothèques, public address, etc.

Logo specifications

The Arcam Logo is a noteworthy advancement in the world of additive manufacturing, particularly in the field of metal 3D printing. Developed by Arcam, a company known for its pioneering work in electron beam melting technology, the Logo is designed to provide high-quality and efficient metal part production, catering primarily to industries such as aerospace, medical, and mold making.

One of the standout features of the Arcam Logo is its use of electron beam melting (EBM) technology. This innovative process utilizes a focused beam of electrons to melt metal powder layer by layer, allowing for the creation of complex geometries that traditional manufacturing methods cannot achieve. By leveraging EBM, the Arcam Logo enables manufacturers to produce lightweight structures with intricate designs, which is particularly beneficial in applications where weight reduction is critical.

Another significant characteristic of the Arcam Logo is its ability to utilize a wide range of metal materials, including titanium, cobalt chrome, and other alloys. This versatility makes it suitable for various applications, from producing custom implants in the medical field to crafting high-performance aerospace components. The machine's software is also designed to optimize the printing process, resulting in improved surface finishes and reduced post-processing time.

The Arcam Logo incorporates advanced features such as an integrated powder handling system that enhances efficiency and safety during the printing process. This system minimizes powder exposure to operators while ensuring optimal powder management, which is crucial for maintaining the quality of the printed parts.

Additionally, the Arcam Logo's user-friendly interface simplifies the operation and monitoring of the printing process. Operators can easily manage print jobs, review production parameters, and make necessary adjustments in real time, ensuring that the manufacturing process is smooth and efficient.

In summary, the Arcam Logo stands out in the realm of metal 3D printing through its advanced electron beam melting technology, versatile material capabilities, and innovative features that enhance efficiency and user experience.
