Home Studio AUDIO connections



The above picture shows the internal AUDIO connections of my Home Studio. All AUDIO is routed through the Phonic MR2643X mixer. This 18 channel (10 mono, 4 stereo) mixer has 3 band eq with mid sweep and 4 band eq for stereo channels, channels inserts and the channels can be switched to the sub-groups and/or main output. It has a built-in digital effects processor, 4 sub groups, 6 aux sends/returns, stereo out and mono-sum out. It can be mounted in a 19" rack.

Another centre piece of the set-up is a Pentium IV 1.6 GHz with 1 GB RAM, Maxtor 80GB/7200rpm harddisk, Nvidia GeForce2 MX/MX400 dual graphics card with two LCD screens (17"and 15"), one CD-ROM station, one CD-RW station and all other standard equipment, like mouse, keyboard, etc. This dedicated music PC is connected to a home UTP network to use other peripherals, like printers and ADSL internet connection. The PC contains two sound cards;

1. Roland Studio Package Pro (SI-24).
This package consists of a digital mixer with built-in 8IN/6OUT (analogue), 24bit/96kHz audio interface with motorized faders, surround sound mixing, etc. together with Logic or Cakewalk software (Which I'm not using.) It is connected to the PC through a PCI card. It has XLR inputs with phantom power.
This mixer/interface makes digital recording very easy and gives you easier control over you recording software, especially when mixing.
The outputs of this mixer are connected to the first 6 inputs of the Phonic mixer. The BUS outputs 1 and 2 from the Phonic mixer are connected to the inputs of the Roland Digital mixer. from there signals can be send to the Philips CDR770 AUDIO CD recorder through digital (coaxial) connections for mastering.

2. Yamaha SW1000XG.
Another high-end PCI soundcard, which I managed to get cheap through the internet. It is one of the best PC cards available and supports both AUDIO and MIDI. It has 6 internal stereo playback devices (12 mono) that can be mixed in the PC using the software mixer to the stereo analog and digital hardware outputs. The SW1000XG has a stereo input for recording, 6 built-in digital effects processors and 5 band EQ.
The external stereo output of the card is connected to stereo channel 11/12 of the mixer. The stereo input of the card is connected to subgroup channels 3 & 4.

At home my gig-rig equipment can be connected to the Home Studio by connecting the stereo outputs of the two Yamaha VL70-m modules to MONO channels 7 & 8 and 9 & 10 of the Phonic mixer.

I transferred my Alesis S4+ MIDI sound module from my old gig-rig to the home studio. I now mainly use it for creating backing tracks.

The Oberheim MC1000 expandable master keyboard contains a Yamaha DB50XG daughterboard. A standard daughterboard is equipped with a 26-pin connector to connect to the WaveBlaster expansion ports of the Creative Soundblaster and compatible soundcards. The Oberheim MC1000 is also prepared to use a daughterboard. This way the master keyboard, normally without a sound generator, becomes an 88 key XG and GM compatible stage piano. The MIDI sounds are fed to the built-in AUDIO out 1/4"connectors.

Next to the built-in digital effects processor of the Phonic mixer, the effects processors on the Yamaha SW1000XG soundcard, the Cubase VST software plug-in effects and the Digitech Studio S100 effects processor, which is connected to the Phonic mixer through the AUX SEND 3 & 4 channels and STEREO AUX RETURN 2, I own a vintage Sansui RA-700 spring reverb. The AUX SEND 1 of the mixer is connected to the Sansui's input. The outputs go the the AUX RETURN 1 (L&R) of the mixer. This way, I can add a very nice and warm, old fashioned type of spring reverb to the recordings. It is especially good for acoustic sounds. Problem with these kind of units is noise, it takes some time to set-up the right gain levels to minimize noise.

The MAIN STEREO OUT of the mixer is connected to a Behringer Powerplay Pro HA4600. This 1U rack unit is a 4 channel stereo headphone amplifier/distribution system. It allows you to connect up to 16 headphones divided in 4 channels. Each channel has 2 band EQ, an AUX IN, a balance knob for the AUX and MAIN signal, an output level knob and switches to mute left or right or to switch to mono-sum.
I have three Sennheiser headphones, a HD25-1, a HD445 and the wireless RS140. The HD25-1 is a professional dynamic closed-back monitoring headphone. It is lightweight and therefore very comfortable. The HD445 is an "audiophile quality" dynamic open-air headphone. Also lightweight. The RS140 is a high-end closed-back wireless headphone.

From the Behringer headphone amplifier the MAIN STEREO OUTPUT is fed to a Better PA-940 amplifier. It has 2 x 150 Watt (@4ohm) output power, 10Hz-30kHz frequency range, overload protector, balanced XLR and 1/4"inputs, separate left and right level control knobs and 2 VU meters.
The power amp feeds a set of Alesis Monitor One Mk2 passive monitor speakers. These monitors have a frequency response of 45-20.000Hz, power handling of 120 Watts (4 ohm) and a sensitivity of 88dB SPL (@1W/m).
