From equalizing the frequencies of halls and sound equipments to the equalization of the tone quality of instrument sounds, this graphic equalizer can be used for a variety of purposes in stereo (2 channel). Connection Features • The SEQ-315 is equipped with two sets of equalization circuits that permit the level control of ± 12dB of each band at 2/3 octaves over a range of 20 Hz to 16 kHz. • Each channel is equipped with controls that adjust the total level without changing the set equalized curve. Equalization with a high signal to noise ratio is consistently achieved. • The SEQ-315 is equipped with two types of input/output jacks. Balanced (XLR) and Unbalanced (standard) so that it can adapt to a wide variety of performance applications. • The unit also comes with the input/ output selector (only for unbalanced), level indicators and the bypass switch. • The SEQ-315 has been designed to be easily mounted on as 19" EIA rack. Before Starting • Make sure the line voltage in your area meets the requirements given on the nameplate. • For use of the SEQ-315 in a foreign country, check with your local Roland dealer. • Plug the SEQ-315 in before turning on the power switch. Precautions • Do not open this unit. • Unplug this unit when not in use for a long period of time. Do not tug by the cord. • Do not place heavy objects on the power cord.

The operation method for using the Balanced input and output (XLR connector) is in the same order as mentioned above. However, the Input Level Selection Switch © and the Output Level Selection Switch <8) will not operate. Therefore, the input/output levels should be adjusted with each connected piece of equipment. Names and Functions of the Controls • Front Panel O© Unbalanced Input Jack A, B (standard) Input from the Unbalanced Input Jacks A, B @ ©on the rear panel will be automatically cancelled by channel when this jack on the front panel is used. (The input from the Balanced Input Jack A, B will not be cancelled). © Bypass Switch Musical instruments, pre-amplifiers, etc. will be directly connected with the stereo amplifiers and PA, etc. with the use of this switch. *The on-off of the bypass switch will be done mechanically. Therefore there is no relation between the on-off of the power switch. However if the bypass switch is manipulated during performance, a click noise will be produced. ©Input Level Indicator ©Output Level Indicator Both of these indicators will light up when there is an overload in the level. © © Level Control A, B Without changing the equalization curve established by the Frequency Control A, B© ©sliders, the whole level can be moved through a range of ±12dB with this slider. 4 0 0 Frequency Control Sliders A, B These sliders control the level of ± 12dB for every frequency. © power Switch (with an indicator) • Rear Panel a b Balanced Input Jack (XLR connector) © Input Level Selection Switch The level can be chosen according to the output level of the connected equipment. *This switch only operates with Unbalanced Input A, B©0@i). * Aside from low level inputs, use at the position of OdBm.
