User manual GAMUT DI 150

[. . . ] This does not only contribute to the touch and feel factor, but is essential for a long-lasting life even in a tough environment. A GamuT product is built to be used daily and we expect our products to be in the "field" for many years to come. Under normal circumstances the DI150 should not need inspection or service for quite a while. The capacitors, for instance, have a promised lifespan of 10 years without degrading. Electrical circuitry considerations All components used in the DI 150 are of the highest quality and have been selected through intensive listing sessions from the PCB itself over the non-magnetic chassis to the WBT output terminals. [. . . ] We follow the international IEC standard for the balanced connections; please ensure that the connected equipment complies with the following: Pin connection of the XLR. You can solve this by reversing the wires in the male plug of your balanced interconnects. The two balanced inputs can be used for any balanced signal source such as a CD player or a separate D/A converter. You can also use them with a pair of RCA female/XLR male adapters for further connection of unbalanced sources. Please note that the adapters are not included in the standard packing, but are available at the dealers. Outputs What goes in must come out!The DI150 offers you plenty of options when connecting: · One pair of unbalanced signal line out · One pair of balanced signal line out · One Tape out · One pair of speaker out The unbalanced and the balanced line out, enable you to connect the DI150 to an external power amplifier to either bi-amp or drive a second set of loudspeakers. In any case; the signal of the output follows the selected level and source. It has a fixed level that follows the actual input level with unity gain. It also has its own buffer amplifier, so that the recording device load does not disturb the main signal path. 7 DI 150 How to operate Selecting a source Select the desired source by pushing the button beside the name of the connected source. A blue dot will light between the text and the button to indicate the selected source. The input selection can be toggled with the remote control, please refer to the section "Remote control" Adjusting the listening level In the middle of the DI 150 front panel you will find the large volume control knob. On the outside parameter of the knob a small blue dot lights up to indicate the level setting. The output level can also be adjusted by the remote control, please refer to the section "remote control" Please note: We have selected an expensive ALPS dual logarithmic potentiometer for setting the listening level. Such a potentiometer cannot make the sound disappear completely, even when you turn it down to the lowest setting. If complete silence is required, enable the Mute function described below. Mute function The DI 150 features a mute function that will efficiently mute the selected signal. The blue dot indicating the selected source is now replaced by a dot indicating the mute function is enabled as shown below. Push the Mute button again to disable the mute function and return to the previously selected source and level. For your comfort and the safety of your equipment, please ensure beforehand that the volume knob has not accidentally been adjusted further towards the maximum output setting before you disable the mute button. The Mute function can also be enabled and disabled by the remote control, please refer to the section "remote control". 8 HTH Direct This function is intended for cases where the DI 150 is connected to a surround preamplifier or processor. Enable the "direct" function by pushing the small switch situated at the left side of the HTH input terminals on the backside of the amplifier. Small characters at the HTH display now indicate "direct". The "direct" function of this input will bypass the volume control and lead the signal directly the output stage of the DI 150. This converts the DI 150 into a power amplifier, driving your front left and right loudspeakers in a surround setup. While the HTH "direct" is enabled and the HTH input is selected, the remote controlled volume will be disabled to avoid conflict with other remote control systems. Recording from an input source You can always record from the actual source selected using the Tape Out. Please note that the output level will match the input level due to the internal buffer in GamuT DI 150. 9 DI 150 The remote control Overview CD player functions: Open/close A-B repeat Repeat one/all Program (CD 1 only) Display dim Remain (CD 1 only) Direct track selection 1-10 / 10+ Play Pause Stop Next track Previous track Fast forward Fast backwards Amplifier functions: Volume up Volume Down Next source toggle Previous source toggle Mute Buttons present, but not in use: Standby Phase 10 Functions Volume up By pushing this button the volume control knob will turn and the blue level indicator dot will rotate clockwise. [. . . ] There are many more things to reproducing music than just reproducing the individual musical tones. But it is the complex spectrum of multiple individual tones created by the musicians' instruments and voices, and not least the reflected signals thereof that create the sounds we detect with our ears and send to our brain to give us the wonderful sensations only music is capable of. It is Gamut´s mission to give to you these unique musical feelings. As with every GamuT product, our amplifiers are designed with the capability of giving you the best possible musical experience, which is synonymous with reproducing all of the essential information in the recording to create the illusion of "being there".
