The IN400 data port is an RS485 serial data port. Twisted pair cabling should be used when connecting RS485 devices, such as CAT3, CAT5, CAT5e or CAT6 UTP cabling. RS485 data networks should be wired in a ‘daisy chain’ configuration with a maximum of 32 devices in the chain.
INSTALLATION All installation work should be done with the power disconnected. The following inforamtion will help with installation. After installation is complete power up all the sources before turning on the IN400. POWER CONNECTION OUTPUT CONNECTIONS (cont.) Ensure the mains voltage supply matches the rear of the IN400 (+/- 10%) Video Video outputs are on either unbalanced RCA sockets (composite) or 15 pin high density female connectors D-connectors (VGA).

Signal generator = 300mVAC, Sine, 1kHz Signal input = DVD1, left channel RCA input Power state of unit: ON Selected source on unit: DVD1 Volume on unit: MIN (lowest volume LED lit). Bass/Treble on unit = flat (use Eq Flat button on IR remote to reset this) Load: Connected to left channel amplifier output Procedure Set volume on unit to max by rotating the volume control CW until the highest LED is lit. Adjust the frequency on the signal generator until the output is 16VAC.
Set volume on unit to max by rotating the volume control CW until the highest LED is lit. (P/F) The residual noise floor should be <1mV. Values to be recorded Value 11a. 12. Noise Left Amp Pass Range <1mV Noise Floor, Right Channel Power Amp Setup Signal generator = OFF Signal input = DVD1, right channel RCA input Power state of unit: ON Selected source on unit: DVD1 Volume on unit: MIN (lowest volume LED lit).

Sources AUX3, AUX4, PC1, PC2 Setup Signal generator = 350mVAC, Sine, 1kHz Signal input = AUX3, left channel RCA input Power state of unit: ON Selected source on unit: AUX3 Volume on unit: MAX (highest volume LED lit).
[Setup for next test] Set the frequency back to 1kHz. 15. Non-Volatile Memory Setting Procedure Ensure power to the unit is ON. Press the power button so that the unit is ON and active. Select source DVD1. Remove mains power (without pressing the power button). Reapply mains power. (P/F) The unit should come back up in power ON mode, with DVD1 selected. Values to be recorded Value 15a. NV Memory Test Pass Range Pass 16.
LISTENING TEST REQUIREMENTS FOR LISTENING TEST SETUP: a) CD Player b) 2x Speakers 18. Listening Test Connect unit to mains power (240VAC). Connect the CD Player to source DVD1. Connect speakers to L and R amplifier outputs. 18.1. Switch on thump Upon switch ON, ensure that thump is of reasonably low level. 18.2. Audio quality Select source DVD1. Ensure that the audio is of crisp, clean sound with no audible distortion artefacts. Repeat this test for all audio inputs, including the mix inputs. 18.3.
