I record guitar using a Line 6 Pod Pro going into a Roland VMC7200 mixing desk via S/PDIF. While the guitar is plugged in, every so often a little audio spike comes through the monitors. Can you tell me what this noise could be and how to stop it?

I'd like to know more about the difference between monitor designs that feature ports and those that do not. How do they differ in terms of sound and performance?

I understand the benefit of having 'limited-range' monitors alongside full-range monitors so that you can hear what your mixes will sound like on small domestic hi-fi systems. But what advantage is there in buying these monitors for £250, when a cheap pair of hi-fi speakers can cost as little as £30?

This smart new unit offers EQ and compression, plus a transformer-coupled Class-A preamp and an unusual Saturation control.

I record brass bands regularly using a stereo mic setup (X/Y or spaced pair). The people I record for are always happy with the results, but I feel I can do better. The sound still doesn't come close enough to a commercial brass band recording. Which mic placement should give the best results?

I've recently upgraded my recording system. Unfortunately the improvements in the signal chain have highlighted more and more the sound of the room I'm in. The other night I tried singing under a couple of futons with really good results. With a touch of reverb the vocal sits in the mix much better and the fans on the computer are no longer heard. Alas, I can't play the guitar under there, so I was thinking of building a small booth, say 3 x 5 x 7 feet, and hanging the futons on the walls to create a deader environment in which to track. Some degree of soundproofing is a bonus, but my main aim is a more neutral acoustic to take and treat with effects. Will I just be swapping one duff sound for another?

Tascam's new Digital Portastudio is the most affordable 24-track workstation on the market. In our exclusive hands-on review, we find out how easy it is to use, and whether its recording quality is as impressive as its track count.

Eventide's classic SP2016 reverb unit has been recreated and enhanced by the original designer. But how does the sound match up to high-spec multi-effects units of today?

How much distance should there be between my monitors and should they face straight forward or be angled toward the listener? Also, as my monitors will be placed against a wall, should some acoustic foam be placed directly behind or between them?
