Audio Connections

Microphone input connections are made via female XLR connectors with pin 2 posi- tive, pin 3 negative and pin 1 ground. 48V phantom power is supplied on pins 2 and

3.Output connections are made via male XLR connectors with pin 2 positive, pin 3 negative and pin 1 ground. If the output is to be used unbalanced, pin 1 should be connected to signal ground and pin 2 to signal hot. Due to the nature of the balanced output stage, pin 3 should be left open for unbalanced operation. See <figure 1> below. Note: This will provide a signal of positive absolute polarity when the preamplifier is being used with a microphone which produces a positive voltage on pin 2 with positive air pres- sure on the front of the diaphragm. While a vast majority of microphones conform to this standard a few do not. Use the phase reverse switch to compensate if necessary.

To connect to the front panel HI-Z input, the input mode selector switch must be positioned in the “HI-Z” location, which changes the preamplifier input source from the mic input connector to the front panel TRS jack. The input impedance of the in- strument input is 2M Ohm (balanced) and 1M Ohm (unbalanced), which is ideal for inserting high impedance sources such as guitars with passive pickups as well as any instrument with a high level output. Wiring of the HI-Z jack is Tip positive, Ring nega- tive, and Sleeve ground. Please note that the gain range of the preamplifier when us- ing the instrument input is –2dB to +48dB in 2dB steps.

Power Connections

A standard three prong AC power cable is included with the m201. For safety, the power supply cord must be connected to a grounded outlet.

The Disconnect Device for the m201 is the Mains plug or the Appliance Coupler on the power supply cord. The Disconnect Device must remain accessible and operable

AC input voltage settings can be adjusted for 100V, 120V, 220V and 240V operation at 50-60Hz. If your line Voltage is 230VAC then use the 240V setting. From the rear of the m201, open the trap door next to the IEC power inlet with a small screwdriver. Care- fully pull the voltage select cam straight out and then insert with the desired voltage
