Emu's APS system takes the company into soundcard territory, but with a comprehensive spec that even includes studio-quality mic amps. Martin Walker tries out this all-in-one experience.

It seems that hardly a month goes by without another soundcard being launched, but there are so many permutations of interesting features that each new model seems to manage to find its own niche in the marketplace. The Emu Audio Production Studio comes from a company that is renowned for its sampling expertise, so, as you might expect, this is the system's main raison d'ĂȘtre. At the centre of its spec lies a 64-voice, 32-channel multitimbral synth/sampler that uses up to 32Mb of your PC system RAM to store samples in SoundFont format. In addition, there's a mini-mixer to deal with the four analogue input channels, four digital input channels, and 16 high-quality EQ and effect blocks which can be patched in any combination to the inputs, sampler, and to a single stereo Wave driver when replaying hard disk audio. There's a single stereo analogue output and two S/PDIF outputs.

The package comes in two main parts. The E-Card is a soundcard with a single pair of analogue inputs and outputs, plus an S/PDIF input and output and a single MIDI I/O connector. To supplement this, the E-Drive fits into a spare 5.25-inch drive bay (just like a CD-ROM drive), and provides a further pair of S/PDIF sockets, a headphone output with level control and an additional two analogue inputs. Unusually, these are designed for use with microphones; they provide phantom power, and each has a separate front-panel switch to add a 20dB pad for line-level use, and its own level control. All analogue inputs and outputs (both on the E-Card and E-Drive) are on balanced quarter-inch jack sockets, and Emu claim that the preamps are of studio quality.

The E-Card is a typical 7-inch-long PCI soundcard, but the MIDI I/O is provided on a separate backplate. The system thus takes up two card slot positions in total, but few people will grumble, since this does allow the card backplate to accommodate quarter-inch jack sockets, rather than the far less robust and reliable 3.5mm ones used by many other manufacturers. The E-Drive mic inputs can each be adjusted using jumpers to suit cheap SoundBlaster-compatible powered or unpowered mics (unbalanced), or more professional dynamic or condenser types. In this configuration, the mic inputs are balanced and 12V phantom power can also be selected. While this is much lower than the standard 48V, it will still be perfectly adequate for many mics.

There's a bit of internal pre-wiring to do: the MIDI I/O backplate connects to the soundcard via a ribbon cable, and another one connects the card and the E-Drive. Finally, a screened headphone cable connects the card and E-Drive. After the card has been inserted in a suitable expansion slot, the new hardware is detected during the reboot and the driver software installed in the normal way. The Emu hardware needs only a single IRQ and base address, and I was up and running in a couple of minutes. The current drivers are standard Windows MME-compatible, although ASIO drivers are already at Beta stage and should become available early next year -- as should Mac drivers.

--- Quote ---Options for Audio Production Studio

8731 - Multi-Output Card
The Multi-Output Card (MOC) is a daughter card option for the Audio Production Studio. It replaces the existing MIDI bracket with an ISA card that contains the MIDI bracket plus three analog, 1/4" stereo outputs for the APS.

This option allows you to send individual audio and MIDI streams to physical outputs via the E-Control Aux bus system.
You can now send individual tracks or combinations of tracks to discreet stereo outputs of the MOC as "sub-outs" or for multi-track recording. You can now have 6 additional, discreet outputs for audio and MIDI when used with the ASIO drivers - making the APS have a total of 8 discreet analog outputs!

It is a very good card

I have a serious problem with this card and may be here is the only place i can find a solution. So please anybody, help me.
Every time i turn on - engage phantom power, there is a noise coming out of the speakers and this noise also included in any of the recordings i may will do (with a condesre mic). The noise is there, even if no mic is pluged in.
Does anybody know what is the couse of this ?

I noticed that one of the outputs (near the Phantom) is a digital output that do not make a contact with ground. All inputs-outputs cheked and make contact with ground except this. So i connect it to a ground point with a small wire, but this do not solve the problem.

Thanks for any help
