Controls & Connections 35 34 32 33 31 30 Rear Panel 4. REAR PANEL (30) RECORD OUT The Record Out Left and Right RCA jacks provide signal output to recording devices, home audio equipment, or external amplifiers. These outputs take the signal from the Main bus, the Aux Send bus, or a combination of both depending on the positions of the Main To Rec/USB(15) and Aux To Rec(16) switches. (31) TAPE IN The Left and Right Tape Input RCA jacks allow stereo receivers, cassette recorders, CD players, or any external equipment, to be added to the Main mix outputs pre-Main Level control. (32) USB INPUT/OUTPUT The USB I/O can be connected directly to any computer with a USB 1.0 (or higher) port for easy plug-and-play operation using a standard "A-B" USB cable. For playback, make sure the Tape/ USB To Mix(18) and Tape/USB To Control(19) switches are set appropriately for desired signal routing. For recording, Make sure the Main To Rec/USB Out(15) and Aux To Rec(16) switches are set appropriately to select your desired signal source. Windows 1. Connect the MM-15USB to the computer using a standard "AB" USB cable. Your computer may automatically set up the MM15USB as its Playback and Recording Device. If not, to set your MM-15USB as such a device, open the control panel. 2. Access Sounds and Audio Devices through the Setting>Control Panel. 3. In the Audio tab, select "USB Audio Device" as the Sound Playback device if you want to send audio from the computer to the MM-15USB. For sending audio from the MM-15USB into the computer, select "USB Audio Device" as the Sound Recording device. 4. Your audio player or recording software may also input and output configurations that need to be to the "USB Audio Device" Mac OS 1. Connect the MM-15USB to your Mac using a standard "A-B" USB cable. 2. Configure your DAW software to select the mixer as your input or output device. This can usually be done in your Hardware Options by selecting "USB Audio Device". 3. Or, you can select "USB Audio Device" as your input device in your Sound options under System Preferences. You may experience a delay in hearing your audio if monitoring in real time. Such a slight delay is called "latency" and is common for many types of software used with this unit. If real time coincidence of the input and amplified signal heard though the computer monitors is required then certain software may be necessary. (33) S/PDIF OPTICAL INPUT AND COAXIAL OUTPUT The S/PDIF I/O exclusively provides a direct digital link between the USB interface and compatible S/PDIF devices. This facilitates a direct digital transfer at sample rates of up to 48kHz. The digital optical input receives S/PDIF digital input through a TOSLINK cable. Digital input is automatically selected when a proper input signal is detected. The digital input will automatically override the audio from the mixer section to the USB output. The digital coaxial output transmits S/PDIF digital output to compatible devices. The coaxial connection requires 75 ohm coaxial cable. Note also that optical input will not be converted to analog, nor will analog be converted to digital coax. The top panel selector buttons have no effect on this operation. Also, this interface does not require the mixer to be on. USB power is all that is needed. When transmission is first initiated, or if it is interrupted, it may be necessary to restart software applications and/or unplug and reconnect USB cable. (34) POWER ON/OFF SWITCH Use this rocker switch to turn the unit on and off. [Note: When operating the power switch, turn the Main Level fader to minimum to avoid audible transient noise]. (35) AC IN SOCKET Connect the corresponding plug of the supplied external AC power adapter to this socket before plugging the AC power adapter into a wall outlet.
