Galaxy Audio CM-170 Check Mate Handheld SPL Sound Pressure Level Meter
Galaxy Audio CM-170 Check Mate Handheld SPL Sound Pressure Level Meter
Today, there is a need to know just how loud your surroundings really are. The cm-170 is an affordable IEC 61672-1 type II SPL meter that competes with some of the best SPL meters on the market. The check mates are inexpensive tools that everybody working in loud environments should own. Windscreen and protective case are included with the check mate models. The check mate series SPL (sound pressure level) meters, first introduced in early 2003, allow musicians, sound contractors, and others to measure SPL in decibels (dB). a decibel is defined as the unit for measuring relative loudness of a sound. We have expanded our line from one check mate SPL meter to four products in the category. We have sold thousands of units to working musicians, DJs, Police departments, sound contractors, racetracks, etc... The cm-170 is the latest in the line of Galaxy audio SPL meters. The cm-170 is similar to our cm-160 model, except that it has data logging with clock feature, fast/slow time weighting, and electronic calibration. The cm-170 comes complete with a carry case, windscreen, USB cable, and software for computer.

Nobsound 1424 Music Spectrum Audio Spectrum Sound Level LED Level Meter Display Analyzer for Hifi (Black)
Nobsound 1424 Music Spectrum Audio Spectrum Sound Level LED Level Meter Display Analyzer for Hifi (Black)
Key Operation: M (short press) --- mode switching ▲ (short press) --- increase brightness ▼ (short press) --- decrease brightness (recommended brightness value 2-4) M (keep pressing) + ▲ (short press) --- increase spectrum speed M (keep pressing) + ▼ (short press) --- decrease spectrum speed (recommended speed 3-4) ▲ (long press) --- switch between LIN (line input) and MIC (microphone input) ▼ (long press) --- switch between L (low gain) and H (high gain) (the best is L by default, can choose H for car spectrum MIC input) NOTE: the setting values need to maintain 30 seconds before they can be automatically saved. Connection: Audio terminal input adopts 3.5mm male headphones, connect it to computer headphone output interface via the audio branch, the other end of the branch connects external audio equipment. Please check whether the audio cable or branch has good contact if the audio has noise or the spectrum has background noise under mute and MIC off mode when using. Potentiometer Function: Input adjustment potentiometer: for adjusting the input signal, for example, the input signal can be attenuated if it is too strong, or adjust this potentiometer to shield some equipment which have strong background noise. Spectrum display amplitude potentiometer: for adjusting the maximum display amplitude after AGC (Automatic Gain) process. After setting, the automatic gain will take this setting value as the maximum amplitude to adjust automatically.(turning to the end can turn off AGC function if you don't need it) Package Includes: 1× AS1424 Music Spectrum 1× USB Cable 1× 3.5mm Male to 2*Female Plug

Nobsound Music Spectrum Audio 15 Level Indicator VU Meter Screen Amplifier VFD LED Display (PJ454)
Nobsound Music Spectrum Audio 15 Level Indicator VU Meter Screen Amplifier VFD LED Display (PJ454)
Important notes: 1. Because of the working conditions of VFD, there is a DC high voltage of about 38V, so don't touch the VFD pins when it is working. 2. Because of the characteristics of VFD, long working brightness will be attenuated, so it will become uneven, is a normal phenomenon. 3. Because the clock module is selected parts, if there is no clock module installed, then the relevant clock function instructions are invalid. 4. When there is no clock function, no signal input and button operation, will enter standby state and display standby characters, in the external port closed setting , after 1 minutes it will close the filament power supply and VFD high voltage. Enter deep standby status. Auto wakeup when there is a signal input or press button operation. Package Includes: 1 * Audio Spectrum Board 2 * Acrylic Board 1 * 3.5mm audio cable 1 * Power cable 1 * 3.5mm 1-TO-2 Plug 1 * Instruction 1 Set Matching screws and pillars
