6.1 The Purpose of the SM IN5

Nowadays, the computer is the hub of the home recording studio. There are many reasons for
this including ease of editing, clarity, digital transfer to CD etc. Traditionally, most computer audio
interface units (standard sound card) been limited to only 2ch inputs that do not offer professional
connectivity for microphones, turn-tables and the like. Some type of mixer device is required to
provide these features. In the case of the turn-tables, a seperate phono pre-amp is also required
to record your analog vinyl records to your PC for CD transfer. The SM IN5 has been designed to
cator for many of these needs.

The SM IN5 provides a solution for users needing to connect a multitude of different devices
including condenser microphones which require phantom power, turn-tables, keyboards, mod-
ules, and even 2 sets of headphones for monitoring to any 2ch recording device. This includes
the computer, DAT recorders, MD recorders, etc.

6.2 The SM IN5 as a recording interface unit

In this example we will record an input from a microphone to the computer.

Step1
Ensure you have the REC inputs & outputs connected correctly to your recording device (com-
puter audiocard, DAT, minidisc, etc) as outlined in section 4.4 of this manual.

Step 2
Connect your microphone to one of the microphone connections on the front of the IN5 and
increase the gain control to an acceptable level. See section 5.1 of this manual.

Step 3
Depress the REC switch on the front panel of the IN5 for the microphone channel you are using
to direct the signal to your REC outputs. This will send the signal from the microphone directly to
your recording device.

Adjust the gain control on the microphone to the correct level desired. You should take note of
the level meter indicators on your recording device while setting the gain. For example, if you are
recording to your computer, check the input level meters of your recording software are register-
ing an acceptable value.

Step 4
Engage recording on your recoring device, and capture the signal from your microphone.

NOTE: For monitoring your signal, simply listen to your monitor speakers (ensure they are con-
nected correctly as described in section 4.3) or headphones connected to the front panel of the
IN5 (as described in section 5.4).
