Setting a Microphone Level
To record a microphone signal using the ISA Two:
1. Using an XLR cable connect the microphone to one of the MIC INPUTS on the rear panel.
2. Select Mic as the input source using the Input switch.
3. If required, activate phantom power using the +48V switch. If you are unsure whether your
microphone requires phantom power, refer to its handbook. It is possible to damage some
microphones (most notably ribbon microphones) by providing phantom power to them.
4. Set the gain of the microphone using the Gain and Trim controls on the front panel while
observing the LED meter. The stepped gain sets the level in 10 dB steps, with Trim providing
a further 20 dB. If the level is too low, use the 30-60 switch to increase the gain range.
5. Use the Z In switch to adjust the input impedance (see "Mic Preamp Input Impedance" on
page 12 for details).
6. Activate the Phase and Filter switches if required.
7. The microphone signal will then be sent to the corresponding rear panel OUTPUT connector.
Setting a Line-level Signal
To record a line-level signal with the ISA Two:
1. Connect the line-level signal, using a ¼" 3-pole TRS jack cable, to one of the rear panel LINE
INPUTS.
2. Select Line as the input source using the front panel Input switch.
3. Set the gain of the line-level signal using the Gain and Trim controls on the front panel while
observing the LED meter. The stepped gain sets the level in 10 dB steps, with Trim providing
a further 20 dB. The 30-60 switch does not affect the line input.
4. The line-level signal signal will then be sent to the corresponding rear panel OUTPUT
connector.
Using the Instrument Input
To record a guitar, bass or other similar instrument with the ISA Two:
1. Plug the instrument directly into one of the Instrument Inputs on the front panel.
2. Select Inst as the input source using the front panel Input switch.
3. Set the gain of the instrument using the Trim control and observing the LED meter.
4. The instrument signal will then be sent to the corresponding rear panel OUTPUT connector.
