REL Operating Instructions STUDIO Sub-Bass System REL Acoustics Ltd North Road, Bridgend Industrial Estate, Bridgend, Mid-Glamorgan, CF31 3TP.
WELCOME Thank you for buying the REL STUDIO Sub Bass system. STUDIO has been carefully hand crafted from the finest materials available and we are sure that it will give you many years of listening pleasure. This manual contains important safety information as well as helpful advice and should be carefully studied before connecting up. WARRANTY At REL we believe in an easy to understand Warranty. STUDIO is covered by a 2 year Warranty (UK Mainland only) which covers both parts and labour.
CONNECTING UP Always switch off your system before disconnecting any wires. To increase the choice and versatility of connecting STUDIO to your system, a set of three gold plated 4mm plugs is included. These will accept large diameter speaker cables and will allow you to join the STUDIO signal cable with your existing speaker cables, if desired.
To Connect to the Power Amplifier: 1. Your existing speaker wires can be twisted together with the signal interconnect to STUDIO and connected to the gold plated 4mm plugs supplied. Alternatively, use your existing plugs or connect the STUDIO lead to a spare set of speaker terminals. In effect the STUDIO is bi-wired from your power amplifier. However, note that there are only three connections to STUDIO.
To Connect to a Separate Preamp Output: 1. Do exactly as Step 1 above for connecting to a dedicated sub-woofer output. 2. Plug this phono connector into one of the separate preamp outputs (assuming there is a left and a right output) and the XLR into the 600 Ohm balanced Line level input of STUDIO. Note that this means STUDIO is sensing only one channel, either right or left. Two separate sub-woofers will be necessary for full stereo compatibility under these circumstances.
differences and that one is too extreme in each direction , ie on maximum settings there is too much bass and at minimum settings there is too little. It will be necessary to test with different types of music with different instruments. At this stage try and get a roughly correct setting. It may take several days before you are completely satisfied that you have found the final best setting.
would be behind the listening chair. Because of the Haas effect (precedence effect of two similar frequencies) we would find such a position very fatiguing if not downright offensive. Fortunately, in the preferred choice of position even with surround sound, very acceptable results can be obtained with a single very low frequency source. Note that these comments apply here because all REL sub-woofers are integrated into the main system by means of the ABC.
CARE AND POLISHING The high quality finish is best cared for by using one of the many proprietary furniture polishes. Alternatively, a soft bristled brush may be used to sweep off any dust falling on the surface. If objects are to be placed upon the top, it is advisable to use a small mat to protect the surface and to avoid risk of any rattles. Everything about STUDIO has been designed and engineered to last a lifetime. SOME DO’S AND DONT’S 1. Always protect the sub-woofer from getting wet. 2.
It is perfectly safe under all normal domestic circumstances as it is fully protected. There are 5 fuses to protect all circuits. ACTIVE BASS CONTROLLER SWITCH versus CROSSOVER FREQUENCY These settings determine the commencement of the upper frequency limit of the sub-woofer. The lowest operating frequency is totally unaffected by these switches. The 4 steps on the Fine control equal 1 step on the Coarse control.
