In these pages, you’ll find a detailed description of the features of the XM910 powered mixer, as well a description of its front and rear panels, step-by-step instructions for its setup and use, and full specifications.
The Samson XM910 Powered Mixer is a comprehensive, all-in-one mixer / power amplifier solution for live sound applications. Here are some of its main features: • Ten channel powered mixer in ergonomically correct kickback enclosure allowing you to easily see and operate the front panel functions.
PAN - Control The XM910’s PAN control is used to place or position the mono signal into the stereo main Left and Right MIX bus. You can create a stereo image by panning some input signals to the left and others to the right.

STEREO INPUT CHANNEL SECTION The XM910 features two stereo input strips, which include channels 7/8 and 9/10. While these channels look very much like the mono channels, they have two inputs so they can accept a stereo signal. The AUX send and Equalizer are laid out on the same as the mono inputs on the control panel, but internally, they are con- trolling a stereo signal path.
PEAK LIMITER - Switch In order to keep the sound loud and clean, the XM910 incorporates an on- board Limiter dynamic processor. When you press the LIMITER switch in, the red LED will illuminate indicating that the dynamics processing is engaged.
POWER AMP SECTION The XM910’s power amplifier section can be configured to operate several ways depending on whether you need MAIN plus MONITOR amplifiers to power your speakers, or if you just need more power for the MAIN speakers. The section below describes the XM910 power amp modes.

Low Cut - switch The MAIN / MONO output of the XM910 includes a LOW CUT (or high pass) filter which rolls off the low frequencies from 75Hz and below at the rate of 18dB per octave. The LOW CUT filter allows you to remove the lower frequencies that you sometime just don’t want to pick up.
For example, when you are using the XM910 mostly for vocals, you may not want to pick up the low end generated by other live instru- ments like bass and low-end synthesizers played out of back-line amplifiers on stage. In many live sound applications, the LOW CUT filter is especially useful for removing stage rumble.

DJ MIXER SECTION Offering extreme flexibility for today’s working musicians, the XM910 incorporates an on-board, two channel stereo DJ mixer. The following section details the control functions used in the XM910’s DJ mixers section. DJ Crossfader The XM910 has a built-in DJ mixer, which can be used to mix line level sources like CD or tape players.
CHANNEL 1– 10 MIC and LINE INPUTS The XM910’s six input channels each have a LINE level, Hi-Z (High Impedance) input and a MIC level, Low-Z (Low impedance) input. By using the GAIN control, you can connect a variety of signal sources from micro- phones to line level devices such as synthesizers, drum machines and direct boxes.

AMP IN - Power Amplifier Left and Right Inputs The Left and Right AMP IN 1/4-inch phone jacks are used to make a direct connection to the XM910’s internal power amplifiers. You can connect a stereo source like the output from an external mixer here. In addition, the Left and Right AMP IN jacks can be used combination with the MAIN Left and Right Output jacks to create an effects loop when connecting an external signal processor to effect the entire system.
The AMP 1 output has two 1/4-inch phone connectors, which are powered outputs used to connect your left side main PA speaker when using the XM910 is stereo mode. When operating in MAIN / MONITOR mode the AMP 1 powered output connectors are used to connect to floor or side fill monitors facing the per- formers.
MODE switch, see the section POWER AMP SECTION on page 9 of this manual. There are three ways in which speakers can be connected to the XM910: A single speaker can be connected to either the A or B jack of AMP 1 and AMP 2, two speakers can be connected in parallel to both the A and B jacks of AMP1 and AMP 2, or a single speaker can be connected to the BRIDGE jack (bridge connection).
BASIC OPERATION The following section explains the basic operation of the XM910. CONNECTING MICROPHONES AND INSTRUMENTS 1. Before connecting mics or instru- ments, make sure that the power of all your systems components, including the XM910, is turned off. Also, make sure that the volume...

The EFX to MAIN/MON control is the overall level control for the DSP effects processor. If you are not using the XM910 in MAIN/ MONITOR or BRIDGE mode, be sure to raise the EFX to MAIN/MON control up on both the MAIN and MAIN/ MONITOR sections so the level of effect is the same in both speakers.
