Digital Audio Connections
PREAMP OUTPUTS
The PREAMP OUTPUTS are fed with the signal from the selected MONITOR source. Connections from here go to the
power amplifier(s). The L & R phono (cinch) connectors should be connected directly to the power amplifier(s)
analogue inputs (usually marked left/right and colour coded white/red) as unbalanced signals. The male XLR-3 recep-
tacles also output the selected MONITOR source as balanced signals. These should be connected directly to a
suitably equipped power amplifier (or amplifiers).
HEADPHONES
A 3.5mm headphone jack is provided on the front panel. Inserting a jack powers down Leema Acoustics power ampli-
fiers connected to the LIPs bus. When a jack is inserted or removed Volume is reduced automatically to a low level in
order to avoid possible hearing damage from an unexpectedly loud source.
Digital Audio Connections
USB
The USB record and replay connection behaves exactly like an external sound card. One USB ‘B’ Type socket is provided
for direct connection to USB 1.1 or higher sockets on PCs or Macs. To avoid clicks and crackles Leema recommend a
direct connection rather than connecting via an external USB hub. Pyxis is ‘plug-and-play’ with PCs running up to date
versions of Windows XP or Windows Vista and Apple Macs. On a PC you will find a new entry in Windows Device
manager labelled ‘USB Audio CODEC’. The device will be then be available to any audio application for recording and
playback.
On Apple Macs the interface will be recognised automatically by OS-X. Once Pyxis is plugged in and powered ON go
to ‘System Preferences' - 'Sounds' and select 'USB Audio CODEC' for input and output. Set volume to maximum.
USB I/O is capable of operating at up to 48 kHz sampling rate, 16 bit
Note : Record level is optimised by using Pyxis gain trim or by setting Agena cartridge gain for best results.
Note : Do NOT send a surround stream to the Pyxis USB input. E.g. Dolby AC3 or DTS. This may result in high level digital
noise being output.
Users of older operating systems may require a specific driver. Suitable drivers can be downloaded from the Leema
Acoustics website : www.leema-acoustics.com Please contact your Leema dealer if necessary.
