Massive Audio V1000.4 Bedienungsanleitung PDF herunterladen

1. General Description

With 16 built-in reverb and multi-effects, the V1000 Digital Multi-Effects DSP delivers outstanding audio performance in a

rapid time-to-market solution at a very affordable price. Since the V1000 incorporates its own RAM and on-board effects, a

complete reverb system can be designed with only the V1000, a low-cost ADC and DAC, and a simple 4-bit controller such

as a rotary encoder etc.

2. Features

• 16 internal ROM programs consisting of effects such as multiple reverbs, echo, phaser, chorus,

flanger, etc.

• Serially programmable SRAM (Writeable Control Store - WCS) for program development or

dynamically changing programs

• Programs run at 128 instructions per word clock. (6 MIPS @ 48 khz sampling frequency)

• 32k location Static Ram provides over 0.68 sec of delay at 48 kHz sampling frequency

• Package outline: SOIC-16/300

• ROHS compliant (PB-free)
