Introduction The Myryad MI 240 Stereo Integrated Amplifier has been designed to deliver a combination of high quality sound reproduction and elegant styling. The amplifier can accept up to eight line-level input sources, including two tape recorders. Outputs are provided for one pair of loudspeakers and for headphones. All functions can be operated using the infra-red remote control handset supplied.
Setting up your system – Rear panel connections 1. POWER inlet Before making any connection, check that the mains voltage setting printed on the rear panel is the same as your local mains supply. Plug the female (socket) end of the power cord into the power inlet on the rear of the amplifier. Plug the male (plug) end of the cord into a "live" wall socket or a suitable heavy duty extension cable. UK version: The mains plug is supplied fitted with a 5A fuse.
4. LOUDSPEAKER outputs The loudspeaker outputs are capable of driving all loudspeakers with rated impedances in the range 4 Ω to 16 Ω. The loudspeaker terminals are high-current binding-posts, coded red or black. The terminals on the left side of the amplifier (viewed from the front) and marked "L" should be wired to the left hand loudspeaker. Those on the right, marked "R", should be wired to the right hand loudspeaker.
12. DVD input Connect the audio signal output cables from a DVD player to these sockets. Use the outputs marked L and R or LF and RF (if the player has a built-in 5.1 channel decoder). NOTE: this input is for an audio signal, not for the digital output from your player. If you do not have a DVD player then any other line level source may be connected to this input. 13. AUX input The audio output from any line level source may be connected to this input.
Using your MI 240 - Front Panel Controls 1. STANDBY When the amplifier is plugged into a live wall socket and the POWER switch is turned ON, it will power up in "standby" mode and the LED (Light Emitting Diode) in the STANDBY button will glow red. In this mode the internal circuitry of the MI 240 is powered up but disabled so that it consumes very little power and is isolated by relays at its inputs and outputs.
5. SOURCE SELECT s and t These buttons scroll up or down through the inputs to select the source you wish to listen to. The display shows which input has been selected. The SOURCE s and t buttons scroll through all the sources except TAPE. The TAPE and LINE DIRECT inputs may be selected by the named input buttons – see below. Whichever source is selected will be sent both to the loudspeakers and to the TAPE REC and CD-R REC output sockets for recording.
System Operation with Smart My-Link When used as a linked system (e.g. an Integrated Amplifier with a CD Player and/or Tuner), Myryad products equipped with “Smart My-Link” have a number of extra features that make the system as a whole easier and quicker to use than a normal hi-fi. These include: Start-on-Play (CD): Press play on the CD player (or the remote control) and the CD player and amplifier will both switch out of standby (if necessary) and the CD will play.
MENU When this key is pressed the amplifier goes into setup mode. The 5,6,3,4and SEL keys are used to navigate the Control Menu (see below). MENU can also be used to exit setup mode. EXIT This key also exits setup mode. SEL This key is used to “Select” (confirm) information in setup mode. 5,6,3,4. These keys are used to navigate in the menu. In general the up and down keys are used to select which parameter is to be adjusted while the left / right keys adjust the parameter which has been selected.
Display on/off The MI 240 is supplied set to “display-on” mode. This means that the display will be illuminated at all times. When the display on/off function is chosen from the menu the display will read “DISPLAY MODE”. If the SEL key is pressed the display will read “DISPLAY OFF”. A further press of the SEL key will switch the amplifier into “display-off” mode and the display will briefly read “DONE” before automatically exiting the menu.
Power-Save-Mode on/off When the MI 240 is linked to other Myryad components using the “Smart My-Link”, one of the features available is the Power-Save-Mode (PSM). This has the effect of automatically switching a CD player (for example) into standby if the CD input on the amplifier has not been selected for the past 10 minutes (see System Operation with Smart My-Link). It is possible to switch this feature off, so that all linked units stay “awake” together if that is preferred.
INSTALLING AND REPLACING BATTERIES The remote handset uses four 1.5 V type AAA batteries. To fit new batteries first open the battery compartment in the rear of the handset and remove any existing batteries. Fit the new ones as directed by the symbols printed inside the battery compartment, then replace the battery compartment cover. The batteries should always be removed if they are discharged (indicated by no remote control operation or by operation only at very short range).
