Instructions for use Thank you for purchasing the Musical Fidelity Nu-Vista 800 integrated amplifier. The Nu-Vista 800 uses our tried and tested ultra-low distortion power amplifier circuitry, which has enough current reserve to drive even the most demanding speakers with ease. The low noise and distortion, high-quality Nu-Vista preamplifier uses valve* circuits used in our original Nu-Vista products, redesigned, to fulfil our latest practices and expectations.
* UK English “valve” mentioned hereafter, refers to the ‘electron valve’ kind, also known as electron “tube” in other parts of the world.

GENERAL ADVICE Installation, Precautions & User Information This new Nu-Vista 800 is designed and built to provide trouble-free performance, but as with all electronic devices it is necessary to observe a few precautions: • Heed all warnings shown on the back of the product. • Only connect the Nu-Vista 800 to a mains outlet having the same voltage as marked at the back of the unit. • Always ensure that when disconnecting and reconnecting your audio equipment the mains supply is switched off.
INSTALLATION Introduction Congratulations on the purchase of the new Nu-Vista 800 integrated amplifier. Great attention has been paid to internal layout, isolating each circuit section to prevent possible interaction. The unit features a finely tuned and tweaked Nu-Vista valve preamplifier, for smooth sound coupled with low noise and virtually no distortion. The power amplifier consists of two top quality power amplifiers for the absolute best in separation and imaging.

REMOTE CONTROL The universal remote control shown below enables functions from this and related units to be operated from a convenient distance. Equivalent buttons on the remote control have the same functions as those on the front panel of the unit. Other functions are only available by remote control. As the handset uses an invisible infra-red light beam, the front edge must be pointed directly towards the receiver window at the front of the player, without visual obstruction between them.
OPERATION Starting Once all connections are made, switch on the unit, using the POWER button front of the unit. The display will light up and base LEDs (under front panel) will show RED. This means the speaker outputs are muted, and will remain in this state for about 12 seconds, so no sound will be heard from the speakers. Once the delay is up, the base LEDs go green, indicating unit is ready for use, and any source material selected and playing will be heard through the speakers.
OPERATION BALANCED . 60.0 BALANCED To use the BALANCED input, connect source balanced outputs to the BALANCED input sockets (see page 7). Select BALANCED input by rotating the source select control so BALANCED is displayed. Pressing the corresponding button on the remote handset has the same effect (see page 8). ILLUMINATIONS When used in darker environments, for example listening or home theatre rooms. It is possible to switch off selected features to minimise distraction.

PROBLEMS? Basic problem-solving with an amplifier is similar to troubleshooting other electrical or electronic equipment. Always check the most obvious possible causes first, such as the following examples: Problem Probable Cause Remedy No power when POWER button is pressed. Mains power plug is not fully inserted into rear socket. Plug in securely. No sound Mute function is still active.
