Front Panel Controls / Features
1. 1/4 inch TRS instrument HI-Z input -
Designed to accommodate a wide variety of high impedance input sources,
making the m103 an excellent choice as a DI instrument input.
2. PEAK INDICATOR -
The LED peak indicator, which monitors the signal at the output of the mic preamplifier, illuminates
green at -10dBu and red at +16dB (12dB before clipping). Located between the HI-Z input and GAIN controls.
3. GAIN CONTROL -
The gain control has 12 positions and adjusts the voltage gain on the microphone input from 10dB
to 65dB in 5dB steps. When using the instrument input, the gain range is –10dB to 45dB in 5dB steps.
4. 48V PHANTOM POWER -
This switch provides 48 volts to power condenser microphones. The phantom power switch
(labeled 48V) connects the +48V power supply to pins 2 and 3 on the XLR input connector. LED indicator illuminates
red when active or phantom power on or is present from another source (mixer, interface).
5. RIBBON SWITCH -
This switch activates ribbon mic mode (also great for dynamic mics). This mode activates the
relay bypass of phantom power decoupling capacitors, increases microphone input impedance, and locks out 48V
phantom power to prevent accidental damage to delicate ribbon microphones. LED indicator illuminates white
when active.
6. 75Hz HIGH PASS FILTER
- Sometimes referred to as a bass roll-off, the high pass filter rolls off at 75Hz. This 12dB/
