This slither card can be used as an input device in both the PCM-H64 expansion rack and the LRX2 location recorder. In microphone mode, each channel can provide up to 65dB of mic gain individually adjustable in 1dB steps to allow for careful trimming of mic signals. Phantom power is available on each input and can be switched individually. Alternatively, any input can be switch to line mode. Each input is then fed to high quality 192k 24bit analogue to digital converters.¹

The card plugs directly into the PCM-H64 or LRX2 system and the interconnections are made available on a 25way female D-type. The card can optionally be supplied with two short adapter looms made from high quality microphone cable which convert the D-types to female XLR connectors.

¹ Please note that 192kHz operation is not currently fully supported in the LRX2.

Originally designed as an input card for the popular PCM-H64 system, the DAC16 slither card is also used in the LRX2 location recorder. This card provides 16 channels of high quality digital to analogue conversion at all standard sample rates up to 192kHz with 24bit precision.¹

The card plugs directly into the PCM-H64 or LRX2 system and the inputs are made available on a 25way female D-type. The card is normally supplied with two female XLR to 25way adapter looms.

¹ Please note that 192kHz operation is not currently fully supported in the LRX2.

SPECIFICATIONS
 
16 channels of electronically balanced analogue output on D-type 25 way connector. Break-out cables used to break signals out to XLR. If the output signal is terminated to a single ended output +6dB is added to the signal.

Originally designed as an input/output card for the popular PCM-H64 system, the AES16 slither card is also used in the LRX2 location recorder. This card provides 16 channels of high quality digital interface to full AES-3 specification and at all standard sample rates up to 96kHz.¹

The card plugs directly into the PCM-H64 or LRX2 system and the interconnections are made available on a 25way female D-type. The card is normally supplied with two adapter looms which convert the D-types to XLR connectors.

¹ Please note that 192kHz operation is not currently fully supported in the LRX2.

The SADiE MADI slither provides optical and electrical MADI input and output for the LRX2¹ portable multitrack recorder.

It supports both the original 56 channel MADI standard, and the subsequent AES10-2003 revision which allows 64 channel operation (sometimes known as MADI-X). The LRX2 can assign its record channels either all to MADI, or to any combination of MADI plus analogue, microphone, or AES inputs. This often proves useful in situations such as recording a live feed via MADI from the FOH desk, while connecting local microphones directly to the LRX2 to record ambience and audience noise.

Connections include Optical TX, Optical RX, MADI in, MADI out, Clock in, and Clock out.

¹Note that the MADI slither is only suitable for the LRX2. The PCM-H64 series incorporate their own dedicated MADI in/out modules.
