User manual MYRYAD MI120

[. . . ] CAUTION: TO PREVENT A FIRE OR SHOCK HAZARD, DO NOT PERMIT THIS PRODUCT TO BECOME WET. IF LIQUID IS ACCIDENTALLY SPILLED ON IT, IMMEDIATELY SHUT OFF ITS POWER AT THE WALL SOCKET AND UNPLUG THE AC POWER CORD. ALLOW SUFFICIENT TIME FOR COMPLETE EVAPORATION TO OCCUR BEFORE OPERATING THE AMPLIFIER AGAIN. IF THE LIQUID IS ANYTHING BUT WATER AND/OR ALCOHOL, THE AMPLIFIER SHOULD BE EXAMINED BY A QUALIFIED SERVICE TECHNICIAN BEFORE IT IS USED AGAIN. [. . . ] In this mode the internal circuitry of the MI 120 is powered up, but disabled so that it consumes very little power and is isolated by relays at its inputs and outputs. When the STANDBY button is pressed the amplifier circuitry will be activated, the input used last automatically selected and, after a few seconds delay, the loudspeaker outputs will be connected to the amplifier. The LED in the STANDBY button will change to blue and the LEDs in the button of the selected input and the volume control will both light up. When first switched out of STANDBY after POWER ON, the CD input will be selected by default. When the STANDBY button is pressed again the amplifier will be returned to standby mode. The LED in the STANDBY button will illuminate again and all other LEDs on the amplifier will be extinguished. CAUTION: WHEN IN STANDBY MODE THE INTERNAL CIRCUITRY OF THE MI 120 IS STILL LIVE, SO ALL SAFETY PRECAUTIONS MUST BE FOLLOWED. 9 Video input Connect the audio signal output cables from a video-related source such as video cassette recorder or TV set to these sockets. Alternatively any other line level source may be connected to this input. The infra-red (IR) remote control receiver is mounted behind this circular window. It must therefore not be obscured when the amplifier is to be operated using the remote control handset. Where possible it is best to arrange that the IR window is in "line-of-sight" of the remote handset. The headphones output is not muted when switching in and out of STANDBY mode, so it is recommended that headphones are unplugged from the amplifier before switching to standby mode and plugged in again after switch-on. 5 Tape 1 (Monitor) When you press the TAPE 1 button you can hear the output signal from a tape deck connected to the TAPE 1 PLAY sockets on the rear panel. This is a "toggle" function switch: you press it once to engage and press again to disengage. The blue LED in the centre of the TAPE 1 button illuminates to indicate that TAPE 1 is engaged. Pressing the TAPE 1 button has no effect on the other input select buttons. The signal source selected by the other input select buttons will be fed to the TAPE 1 REC output sockets, irrespective of whether the TAPE 1 button is engaged or not. Thus, if you have a "three-head" tape deck that permits off-tape monitoring you can use the TAPE 1 button to switch back and forth between the source signal and the offtape signal, to check its quality, whilst the recording is in progress. NOTE: IF THE TAPE 1 BUTTON IS ENGAGED WITH NO SIGNAL SOURCE CONNECTED TO THE TAPE 1 PLAY SOCKETS, OR WITH NO TAPE RUNNING, THEN YOU WILL HEAR ONLY SILENCE, REGARDLESS OF THE SETTINGS OF ANY OF THE OTHER CONTROLS. 3 Volume control The volume control adjusts the sound level for both loudspeakers and headphones. It does not affect the signals fed to the TAPE 1 and TAPE 2 REC sockets so it can safely be adjusted whilst making a recording. The blue LED pointer in the volume control illuminates when the amplifier is operating. The pointer may also be used to facilitate manual operation of the control. When the MUTE mode is engaged using the remote control, the volume control pointer will flash repeatedly to indicate this condition. Always press MUTE on the remote handset again to disengage the function before advancing the volume control setting. 10 Tuner input Connect the audio output cables from a radio tuner to these sockets. If you do not have a tuner then any other line level source may be connected to this input. 11 AUX input The audio output from any line level source may be connected to this input.
