4. DESCRIPTION & FEATURES SAMI-603 is an installation audio mixer in standard rack format, featuring 1 MIC input + 4 MIC/LINE Stereo inputs + 1 LINE Stereo input and 3 outputs that can be configured as 1 stereo couple + 1 mono or 3 independent mono.
The SAMI-603 mixer has been specially designed to be installed in a standard 19" rack, taking up 1U. Due to its low power consumption and heat sink, the SAMI-603 does not need any fan cooling. However, avoid installing it in dusty environments and/or in a location with extreme temperature and moisture.
6. START-UP & OPERATION 6.1 Connections 6.1.1 Inputs The SAMI-603 inputs accept two types of audio signals (mono microphone and/or stereo line). For inputs accepting both types of signals, the selection is done using a MIC/LINE switch located on the rear panel.

CD and LINE sources and other devices capable of producing audio signals, the LINE inputs 2-5 of the SAMI-603 are standard line inputs (0dBV) and the sensitivity of the LINE input #6 can be selected (0/-6dBV) by internal jumper (the default position is 0dBV). A sensitivity of -6dBV is ideal for low-level sound sources such as media players, portable MP3 players, tablets, computers, mobile phones, etc.
6.1.2 Outputs SAMI-603 has three electronically balanced outputs with Euroblock connectors Connection is made according to the following diagram: The master level of each mixer output (OUT A, B or C) must be adjusted so that the overload indicators (CLIP) are not permanently lit on the system amplifiers, but at most on the lowest frequencies marking the rhythm.
6.1.3 Other connections on the back panel 1. AUX/REC output with a nominal output of 0dBV (10kΩ load) and an extra gain setting of +6dB, enabled by internal jumper (0dBV is the default position). Please note that the “Output Sensitivity” selector always affects the main output.
Plug the external PSU to the DC IN connector located on the rear panel and then, after connecting it to the power outlet, press the on/off switch to power the unit. Even the power-up noise of SAMI-603 is minimal, we highly recommend to power up all equipment in the following order: 1.
6.3 Mono/Stereo modes and Inputs-Outputs assignment On the front panel, each input channel has a master level control (VOL) and 3 buttons (A, B and C) to assign its signal to one or more outputs of the unit. When one of these buttons is engaged, the signal is sent to the corresponding output.
Cable shields, when connected to the chassis, must never be linked together. This will avoid ground loops. The SAMI-603 mixer has been designed to produce the lowest background noise. Independently from the electronic design, the resulting background noise directly relies on the correct use and installation of the mixing unit.
