Choosing your studio recording equipment
Start by determining what you want to record simultaneously: a voice, an instrument, or multiple sources. To choose an audio interface, compare the number and type of inputs, the outputs required for your setup, and the connection to your computer. The Universal Audio VOLT and Apollo models, as well as Blackstar Polar, should be compared using their product pages: their names alone do not confirm the connectivity or compatibility with your system.
For monitoring, distinguish between audio interfaces and studio monitors. The Fluid Audio C5 are advertised as 5-inch studio monitors sold as a pair. Before connecting them to your equipment, check their connections and your interface's outputs, then plan for the appropriate cables. Being sold as a pair is a factor to consider when comparing offers.
If you are completing an existing setup, first identify the role of the new device. A model such as the Universal Audio Solo/610 Classic Tube may be worth considering for a preamp requirement, subject to checking its specifications on the product page. For the Apollo models offered in Essentials+, Studio+, or Ultimate+ editions, compare the exact contents of each offer without inferring the included items from its name. You can also find studio accessories to complete your setup according to its needs.
