Seeing the malfunction with your own eyes may illuminate the problem better than if you simply acted on someone else’s description, or worse yet your own assumptions. It is usually a good idea to verify the exact nature of the malfunction before proceeding with troubleshooting strategies, even if someone has already informed you of the problem. All audio signal cables (including the speaker cables) may be unplugged to provide access for your meter’s test probes.Īt what point in the system would you begin testing for the presence of an audio signal? Explain why you chose that point, and describe your subsequent actions based on the results of that test.

Despite all these good indicators, though, no sound is heard from the speakers.īeing prepared at all times to troubleshoot electronic systems, you have a digital multimeter close by which you may use to check for the presence of audio signals (set the meter to measure AC millivolts). The CD player indicates the disk is being played, and that it is presently playing a song. All control knobs seem to be set to their proper positions, as well. All components in the system are turned on, as indicated by power lights on the front panels. Suppose this system has a problem: no sound at all coming out of either speaker. The CD player generates the audio signal to be amplified, while the equalizer/preamp modifies the tone of the signal to suit the listener’s preferences and the power amplifier provides adequate power to drive the speakers. This cancels out electromagnetic interference whilst offering outstanding power and maintaining consistent tonality, no matter how loud it’s played.Examine the following “component” stereo system closely: In Edge we take this one step further, using opposing symmetry twin toroidal transformers. As a result, the Cambridge Audio Edge W delivers a more faithful reproduction of the original recording an impressively detailed three-dimensional sound, with striking staging and focus More musical detailĬambridge Audio pioneered the use of toroidal transformers in amplifiers, which led to improved performance. To remove the barriers between you and your music, Cambridge Audio has worked hard to minimise the number of components in the signal path. Just 14 components in the signal pathĪlthough minimal in its exterior design, the Cambridge Audio Edge W has some complex audio engineering inside. The end result is a power amplifier that truly brings an original recording to life like no other. And created our system with components that simply sounded the best. It’s all down to how we chose the componentry inside – nothing was picked on price, specs or measured performance. The sound is finely balanced, with a musical depth and clarity that comes through with every note. It delivers our breath-taking, unadulterated British sound – nothing added, nothing taken away.įor all its power, the Cambridge Audio Edge W is remarkably detailed. With just 14 hand-picked components, Edge W has one of the cleanest signal paths available. When you do turn it up, expect nothing but a dynamic and punchy sound that captures all the musicality of your songs. The Cambridge Audio Edge W is made to be played loud.
