ASP-MG24
4.0 REAR PANEL FEATURES
1. Power Supply Socket
An external UL rated 120v AC power supply has been included with the ASP-MG24. Only use the
provided power supply due to the specific DC voltages required to operate the unit.
2. Input Connectors
There are two removable 3 Pin Phoenix type connectors for providing input signal to the unit. They
can accept either a balanced or unbalanced signal. For balanced signals connect (Ground to GND),
(Positive signal to +) and (Negative signal to -). For unbalanced signals connect the (- to the GND
together) and the Positive to +).
3. Mic / Line Level Selection
Each Input has the capability to accept either a microphone or line level signal. Prior to connecting the
inputs make sure the software input gain that apply to the channel routing are set to -10dB. Also the
limiters are set to +20dB for gain setup. Prior to applying signal to the input you must set the analog
gain switch to match the type of input you are using. The Line position gain is calibrated for 0dBu or
unity gain within the DSP software. The Mic position is calibrated for -30dBu when the DSP gain is set
for unity or 0dB. If more gain is needed carefully turn the up the appropriate channel DSP gain in the
software. If you will be using a microphone it is recommended when starting to turn the input gain to
-40dB and slowly bring up the input gain to the desired level.
4. Output Connectors
There are four removable 3 Pin Phoenix type connectors for providing output signal. They can deliver
either a balanced or unbalanced signal. For balanced signals connect (Ground to GND), (Positive
signal to +) and (Negative signal to -). For unbalanced signals connect the (- to the GND together)
and the Positive to +).
5. RJ45 Port
This port is used for remote system controllers. For Ethernet connection an optional card is required.
