Musical Fidelity Guide to Connections and Setup for the X-150 Integrated Amplifier

All input, output and power connections should be made with the mains power switched OFF.

INPUT CONNECTIONS

The X-150 Integrated amplifier has a pair of RCA inputs on the rear panel marked PHONO which are intended for moving magnet (MM) pickups.

Some turntable/pickup arm combinations are fitted with an extra wire for chassis earthing. This should be connected to the earth terminal on the back panel.

The X-150 also has three “line level” inputs controlled by the internal volume setting. They all have the same input sensitivity, and are therefore suitable for use with any source component having an output of at least 300mV. The three pairs of sockets on the rear panel are marked INPUT 2, 3 and 4 corresponding with the blue function indicator LEDs on the front panel.

Connect the left and right outputs from your audio components to each of the three sets of RCA sockets, to suit your own order of preference.

Connect the the X-150’s TAPE RECord output sockets to the line input sockets of your tape deck.

CONNECTIONS

OUTPUT CONNECTIONS

Connect your loudspeakers to the pairs of terminals on the back panel marked as LEFT and RIGHT SPEAKER outputs.

Note: the combined load impedance must not be less than 4 ohms.

PRE-AMPLIFIER OUTPUT

The X-150 amplifier has its pre-amplifier output available from RCA sockets on the back panel marked PRE-OUT, and is controlled by the volume adjustment.

This is to allow “bi-amplification” using suitable external amplifiers and crossover networks to power the speaker drive components separately, giving noticeable improvement in clarity, imaging and bass weight.

In this arrangement, typically the X-150’s speaker outputs are used to drive the speaker’s “tweeter” (high audio frequen- cies), and an external stereo amplifier drives the “woofer” (low frequencies). The X-150’s PRE OUT RCA sockets would therefore be connected to the input of the external “woofer” amplifier in this example.

If you are in doubt about bi-amplifica- tion, please contact your dealer for advice.

GENERAL ADVICE

INSTALLATION PRECAUTIONS and USER INFORMATION

Your new X-150 Integrated amplifier 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 X-150 Integrated amplifier 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.

Position the mains lead and signal interconnects where they are not likely to be walked on or trapped by items placed on them.

Do not use near water, or place water-filled containers on the amplifier, for example, flower vases or potted plants. If water does spill inside, immediately pull out the mains plug from the wall socket and inform your dealer, who should then check the unit before further use.

Entry of liquid into the amplifier is dangerous, and may cause electric shock or fire hazard.

Do not place the unit near heat sources such as radiators, direct sunlight or other equipment. The case of this amplifier can run at high temperatures - operate the unit in a well ventilated area, and do not touch the cabinet sides or top after periods of use at high output power.

Do not remove covers or try to gain access to the inside. There are no internal user adjustments. Refer all service work to an authorised Musical Fidelity agent.

NOTE: Unauthorised opening of the equipment will invalidate any warranty claims.

There are fuses inside the X-150 amplifier. In the unlikely event that one blows, refer the unit to your audio dealer. Do NOT try to replace the fuses yourself as this will invalidate the warranty.

Dust regularly with a soft cloth or soft brush, but be careful when using cleaning or polishing agents - they may harm the surface finish.

The electronics in modern hi-fi equipment is complex and may, therefore, be adversely affected or damaged by lightning. For protection of your audio system during electrical storms, remove the mains plugs and disconnect any aerial lead.

If after-sales service is required, to help your dealer identify the X-150 Integrated amplifier please quote the serial number located on the rear panel of the unit.

RADIO FREQUENCY INTERFERENCE (R.F.I)

This product has been tested to ensure that its operation is not adversely affected by normal back- ground levels of R.F.I., and that it does not itself generate excessive amounts of interference. However, if a problem persists, please contact your Musical Fidelity agent.
