Mic Pre Module Frequently Asked Questions

The Mic Pre module provides your Symphony I/O with up to 8 mic preamps to your system. Here are answers to some common questions our customers have about the Mic Pre module:


Q. Does it add 8 additional channels to my system?

A. No. It only provides the option of selecting a mic pre to your existing card in slot 1.

For example: If you have an 8×8 module in slot 1 of your Symphony I/O, this provides you with 8 channels of analog line-level input. If this is the only card you have installed, you’d have to use external mic preamps to connect microphones to this system.

By adding a Mic Pre module in slot 2, this provides those 8 channels with high-quality mic preamps internally instead. Whether to use your 8 analog inputs as line-level or mic preamps is selectable in the Maestro 2 software’s Input screen.


Q. Do I plug my mic into one of the four ¼” inputs on the Mic Pre module? What are they for?

A. These ¼” inputs are for connecting high impedance sources such as an electric guitar, bass guitar, or keyboards to the Mic Pre card. It makes it convenient to connect these ¼” sources to the Symphony instead of using an adapter to plug into the XLR input of the card in Slot 1. Enable these in the Maestro 2 software’s Input screen by selecting “Instrument” as the channel’s Analog Source.


Q. What are the Inserts Send/Return for? How do you use them? Where is the insert point?

A. This is a hardware insert for the Microphone Preamps. They are used to insert additional equipment such as Compressors and Equalizers to your input path. You turn Inserts On/Off via the Maestro 2 software’s Input screen, and the insert option is only visible on channels that have the source set to “Mic” or “Instrument”. The insert point is after the preamp and high-pass filter but before the A/D conversion stage.


Q. Can I use the Mic Pre module with the 2×6 analog card or the 16 Digital In + 16 Analog Out card (sometimes called the 16ch D/A card)?

A. No. The Mic Pre module cannot be used with the 2×6 analog card or the 16 digital in + 16 analog out card because they do not have at least 8 channels of analog input available.


Q. Can I use the Mic Pre module with the 16×16 analog I/O card or 16 Analog In + 16 Digital Out card?

A. Yes. The first 8 channels of the 16 input channels can be set as “Mic” via the Maestro 2 software’s Input screen, and the channels 9-16 are limited to line-level.

¿MiC es compatible con el iPhone 5?

¡SÍ! MiC ha sido probado y es totalmente compatible con el iPhone 5 cuando se utiliza con el adaptador de Apple 30 pin – Lightning. El adaptador proporciona la misma conexión digital de alta calidad cuando se conecta directamente al puerto de 30 pin en los modelos anteriores de iPad y iPhone. Los adaptadores están disponibles directamente sólo a través de Apple y no serán vendidos por Apogee.





Can I connect a microphone to JAM?

JAM is optimized for electric instruments, like guitar and bass specifically. However, with its 40 dB of input gain, JAM can be used with certain dynamic microphones using an XLR to 1/4” cable or adapter. We have tested both Shure SM57 and SM58 dynamic microphones and each worked well when recording loud sources such as a singer. We recommend you purchase an impedance matching transformer if you choose to use JAM for vocals.
Additionally, since JAM is a guitar interface, Phantom Power (48v) is not included. Condenser microphones which require Phantom Power will not work unless they have their own built-in power supply, such as a battery. It should be noted even with a built-in power supply, the amount of gain available is more suited to instruments rather than microphones.
