The flattest response for each control is obtained in the 12 o'clock position, conveniently and positively located by a centre click stop. Direct The direct switch is located just to the right of the tone controls. With the direct switch in the depressed position the audio signals completely bypass the tone control stages so that adjustment of the bass or treble controls will not alter the sound. If the tone controls are not often used then it is recommended that the direct switch be left in to achieve the very best performance. 7 Mono The amplifier is in its normal stereo mode when the mono button is out. In this position, the left and right input signals are amplified independently to feed the corresponding loudspeaker outputs. When the mono button is pushed in the left and right signals are mixed together and the combined signal is routed to both loudspeakers. This is particularly useful when listening to mono records or tapes (as much low frequency out-of-phase rumble can be eliminated) or to remove excessive hiss from FM broadcasts. It is also invaluable for checking speaker phasing in a stereo hi fi system. SP2 switch When this switch is in the depressed position the output from the amplifier is channelled through the loudspeaker outlets marked 'switched', in addition to those marked 'main'. The 'main' outputs work all the time. If the SP2 switch is out no sound will be heard via loudspeakers connected to the 'switched' terminals. (See Loudspeakers page 5). Phones The headphone socket will accept any headphones fitted with a standard quarter inch (6.35mm) stereo jack plug. The headphones may be operated in parallel with the loudspeaker outlets, or not, as you wish (see Loudspeakers page 5). Tape recording The Delta 90 allows extreme versatility with tape recorders allowing you not only to record from one source but also to listen to another source at the same time. Both sockets are suitable for almost any type of recorder. Tape 1 Connect your tape recorder to the Tape 1 sockets using the 'in' sockets for connecting the playback and the 'out' for connecting the recording side of your tape recorder (see page 5). Recording - All the inputs are automatically connected to the recording outlets so to record an input, set the required input, e.g. CD, to play and then set the 'record' selector switch to the required input, CD in this example. Set your recorder Into its recording mode and the required input will be recorded. Setting the 'listen' control to the recorded input, CD in this example, will enable you to listen to the input being recorded. If your tape recorder allows you to monitor the recording, switching to Tape 1 on the 'listen' selector will allow you to listen to the actual recording. If you wish to listen to another input, instead of either the recorded or the recording inputs, select the 'listen' selector to the desired input. Disc for example. Playback - Set the 'listen' selector to Tape 1 and set your tape recorder in the playback mode. Tape 2 Connect your tape recorder as per Tape 1 but using the sockets marked Tape 2. Recording - All the inputs are automatically connected to the recording outlets so to record an input, set the required input, e.g. CD, to play and then set the 'record' selector switch to the required input, CD in this example. Set your recorder into its recording mode and the required input will be recorded. Setting the 'listen' control to the recorded input, CD in this example, will enable you to listen to the input being recorded. The Tape 2 sockets do not allow you to monitor the recording - do not switch the 'record' selector to Tape 2 as this will cause severe feedback and may cause damage to your amplifier and your loudspeakers. If you wish to listen to another input, instead of either the recorded or the recording inputs, select the 'listen' selector to the desired input. Disc for example. Playback - Set the 'listen' selector to Tape 2 and set your tape recorder in the playback mode. Cartridge loading modules These optional accessories are passive, switchable modules designed to modify the input impedance of the amplifier in order to obtain the best match with the cartridge in use. As the Delta 90.2 has a single set of disc inputs (switchable to MM or MC via the switch on the rear panel), then two separate loading modules - one for moving magnet (type ULM/M) and one for moving coil (type ULM/C) cartridges - are available on request from your dealer, distributor or the factory. These modules are user adjustable via a series of small switches. The loading modules should be plugged into the amplifier on the pins located close to the disc input (see section - Removal of top plate below). A set of Instructions is provided with each module. Care should be taken to ensure that only an MM loading module is used in conjunction with moving magnet or high output moving coil cartridges and that only an MC loading module is used in conjunction with normal...
