Bi-wiring and bi-amping loudspeakers

BEFOREYOU START

WARNING: Do not make any connections to your amplifier while it is switched on or connected to the mains supply.

Before switching on please check all connections thoroughly, making sure bare wires or cables are not touching the amplifier in the wrong places (which could cause short circuits) and you have connected positive (+) to positive and negative (–) to negative.

Always ensure that the volume control on your amplifier is set to minimum before starting these procedures.

BI-WIRINGYOUR LOUDSPEAKERS

Bi-wiring improves the sound of your system because it divides the high and low frequency signal currents into separate speaker cables. This avoids signal distortions arising from the high and low frequency currents interacting with one another within a single cable, as in conventionally wired systems.

You will need:

Speakers – with four input terminals each: these will be marked HF (High Frequency + and –) and LF (Low Frequency + and –).

Loudspeaker cables – two pairs of cables per loudspeaker (which may be joined at the amplifier end if your amplifier has only one pair of output terminals per channel, as is the case with P7), or a suitably terminated cable set.

How to bi-wire loudspeakers

1.Remove the terminal links on the rear of your loudspeakers.

NOTE: If you do not remove the shorting links from the speaker terminals, the speakers will still be single-wired!

2.Connect the cables as shown in the diagram below, ensuring correct polarity at all times.

BI-AMPINGYOUR SYSTEM

The performance of your system can be further enhanced over that

English

 

achieved with bi-wiring, by extending the principle one stage further

 

to include separate amplification for the low and high frequency drive

 

units in each loudspeaker enclosure.

 

To bi-amplify your speakers, connect the speaker terminals from one

 

module to one pair of terminals on the speaker. Connect another

 

module, or one channel of a separate power amp, to the other pair of

 

terminals on the speaker, so that two amplifier channels are connected

 

to that speaker; one for low frequencies and one for high frequencies.

 

Ensure that in all cases, the positive terminals on the speakers are

 

connected to the positive (red) terminals on the amplifier, and similarly

 

for the negative (black) terminals.

 

NOTE: In order to bi-amplify your speakers, your speakers will need

 

to be bi-wirable, and have positive and negative terminals for both high

 

frequency (HF) and low frequency (LF) information. If your speakers are

 

bi-wirable, ensure that the links between the HF and LF terminals are

 

removed.

 

How to set up a bi-amped system

 

1.Remove the terminal links on the rear of your loudspeakers.

WARNING:This step is essential or damage to your amplifier may result which is not covered under warranty.

2.Connect the cables as shown in the diagram below, ensuring correct polarity at all times.

3.Use interconnect cables to connect the OUT socket of the first channel to the corresponding IN socket of the adjacent channel of the power amplifier.

Multichannel Power Amplifier specifications

The Arcam Multichannel Power Amplifier stands out in the audio landscape, delivering exceptional performance and versatility for home theater and multi-room audio systems. Known for its hallmark sound quality, this amplifier is designed to elevate the listening experience, leveraging advanced technologies and premium components.

One of the primary features of the Arcam Multichannel Power Amplifier is its high power output, which allows it to drive even the most demanding speakers with ease. With multiple channels typically offering 100-200 watts per channel, the amplifier is capable of providing clear, dynamic sound across all frequencies. This high output ensures that users can enjoy a powerful cinematic experience without distortion, making it ideal for both music and movie playback.

Another key characteristic of the Arcam amplifier is its Class G amplification technology. Unlike traditional Class A or Class AB designs, Class G dynamically adjusts power supply voltages based on the signal level. This results in improved efficiency and lower heat generation while maintaining optimal audio fidelity. As a result, users benefit from enhanced performance during extended listening sessions without the risk of overheating.

The amplifier also incorporates advanced signal processing features, including high-quality DACs (Digital to Analog Converters) and extensive connectivity options. It supports various audio formats and protocols, allowing users to integrate it seamlessly into existing systems, whether utilizing HDMI, analog, or digital connections. This flexibility makes it compatible with a wide range of audio sources, from Blu-ray players to gaming consoles and streaming devices.

Moreover, the Arcam Multichannel Power Amplifier features robust build quality with premium components designed for longevity and reliability. The use of high-grade capacitors, heatsinks, and sturdy chassis construction ensures that the amplifier can withstand rigorous use in diverse environments.

In terms of usability, it often includes features like trigger inputs, remote control operation, and automated standby modes for convenience. User-friendly interfaces and capabilities allow users to customize their listening experience, enhancing their engagement with the audio content.

In summary, the Arcam Multichannel Power Amplifier represents a pinnacle of audio engineering, combining powerful performance, innovative technologies, and user-friendly features. It is an ideal choice for audiophiles and home theater enthusiasts seeking an amplifier that delivers rich, immersive sound quality across multiple channels, while maintaining efficiency and reliability.
