Introduction Congratulations on your purchase of the Samson MIXPAD! One of the smallest mixers ever made, the MIXPAD provides excellent sound quality and a wealth of features normally found only in full-size units. Although it has been designed for easy operation, we suggest you take some time to go through these pages so you can fully understand how we’ve implemented a number of unique functions. This manual covers three models: the MIXPAD 12, MIXPAD 9, and MIXPAD 4. The first two of these a

MIXPAD Features The compact design of the MIXPAD belies an extraordinary versatility. Add excellent sound quality to the equation, and you’ve got a product which is equally useful as a live performance mixer and for field recording applications. Here are some of the MIXPAD’s main features: • In the MIXPAD 12, a total of twelve input channels (including three stereo channels); in the MIXPAD 9, a total of nine input channels (including three stereo channels); in the MIXPAD 4, a total of four inpu

MIXPAD Features • Constant level pan controls for placing each monophonic channel in the left-right stereo spectrum, as well as balance controls that allow you to blend the relative levels of stereo inputs. • Mic input trims that are continuously adjustable from +4 to -50 dB, making it possible to use the MIXPAD with a wide variety of microphones. • The MIXPAD 12 and MIXPAD 9 provide 36 volts of phantom power to all mic inputs, while the MIXPAD 4 provides 18 volts of phantom power (with independ

Guided Tour - MIXPAD 12 / MIXPAD 9 Channels 1: Mic inputs - Provided in monophonic channels only (channels 1 - 6 in the MIXPAD 12 and channels 1 - 3 in the MIXPAD 9). Use these electronically balanced XLR jacks to connect microphones to any of the MIXPAD’s monophonic channels. These are intended to accept signal from low-level, low-impedance mics but can also be used for signal from other sources (such as direct injection boxes) if the channel’s Trim control is turned down (see #2 below).

When both inputs are connected to a stereo channel, the upper input signal (channels 7, 9, and 11 in the MIXPAD 12 and channels 4, 6, and 8 in the MIXPAD 9) is automatically panned hard left and the lower input signal (channels 8, 10, and 12 in the MIXPAD 12 and channels 5, 7, and 9 in the MIXPAD 9) is automatically panned hard right. In this case, the “Balance” knob controls the relative level

Guided Tour - MIXPAD 4 Channels 4: Equalizer (violet) - These knobs determine the amount of boost or attenuation in each of three frequency areas. Each knob provides 15 dB of cut or boost at 12 kHz (High) and 80 Hz (Low) frequencies, and 12 dB of cut or boost at the Mid (2.5 kHz) frequency. The High and Low frequencies utilize shelving curves and the Mid frequency utilizes a bell (peaking) curve. In the stereo channel (channels 3 - 4), the EQ settings affect both inputs, although the signal
