Pioneer DEH-80 PRS 3way+Sub (7 channel) SQ Setup

I have recently upgraded my in car entertainment with a Pioneer head unit.
Set up is as follows
1 x DEH 80 PRS
2 x VSA silk dome tweeters
2 x VSA 3" Midrange speakers
2 x RE 6.5" Mid Bass
1 x Rockford Fosgate t110D2
1 x Lightning Lab 1850D 850w mono Amp
1 x Lightning Lab AM4110 4 channel Amp

DEH 80PRS Settings
LOW - 80hz
MID LOW - 80hz
MID HIGH - 1.2khz
HIGH - 1.6khz

4 channel AMP Settings
LOW ~ 250hz (Bass +6db)
HIGH  255hz~

monobloc AMP Setttings

Used a tone generator to check and get them to playing
tweeters 1.6khz - up
mids 255hz - 1.6khz
midbass 80hz - 250hz
sub 18hz - 80hz

Adjusted the time alignment automatically at first using the built in fuction of the headunit then fine tuned using a doppler effect sound by ear. It just needed a nudge to properly align the singer center and eye level on the dash.

Cdr King TT520 Flash Unit, Optical Slave and Recycle Test, Godox rebrand

I. Slave mode response
First up i tested the optical slave on the TT520 flash and check how it performs. the TT52o is set to "s1" mode, on this mode it will respond to any quick burst of light. the trigger is a Nikon sb28 unit set on repeating flash.

First on 20 flashes @ 10hz

Then on 20flashes @ 20hz

II. Recycle time
After that I tested the recycle time of the TT520 on full power. the TT52o is set to "s1" mode, on this mode it will respond to any quick burst of light. the trigger is a Nikon sb28 unit set on manual 1/64 power.

So far so good, works flawlessly. I like the response time of the slave (s1) and can keep up with the sb28 repeating flash as well as the 3 second recycle time on full power. I will be testing this flash on the field and see how it performs on an actual shoot.

More to come.

Cdr King TT520 Flash Test, Godox rebrand


We'll be looking at the new CDR King TT520 flash. First off this is a manual flash without any TTL functions.

*** note the fake rubber flap, There is nothing under that rubber flap. I think it is a provision for some pc sync connection or external power, made for more advanced models.

Stats are as follows

Specifications on paper
Guide Number 33
Flash Modes M, S1, S2
Tilt 0 – 90°
Swivel 0 – 270°
Power Source 4 * AA batteries
Recycle Time 0.5 – 5s
Output Full, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128
Colour Temperature 5600K +/-200K
Flash Duration 1/800 ~ 1/2000s
Dimensions 190 * 75 * 55mm
Net Weight 286g

Package includes
# 1 x Flash light
# 1 x Protecting bag
# 1 x Mini stand
# 1 x User manual

Test results (Actual)
- Works on camera hotshoe no problem (Canon 7d)
- Works off-camera slave s1 triggered by manual popup flash
- Works off-camera slave s2 ignoring preflash
- Works off-camera mounted on RF 603c wireless tranceivers
- Recycle time is 3 seconds on full power

Power test
Camera : Canon 7d set at f9
All flashes on 1/1 power
Distance 9feet

A quick rough test reveals that the CDR King TT520's power is right in between the YN460 and YN460mkII.

I will be using this flash primarily to test how long it lasts, more to come.

Yongnuo RF-603 flash tranceiver range test

I tried to compare the new Yongnuo RF-603 tranceiver against a Pocket Wizard Flex on a range shoot out.

Camera : Canon 50D + 70-200 IS f2.8L @ 200mm
Flash : 580exII
Triggers : PW flex / YN RF-603
Pocket Wizard Flex
Yongnuo RF-603
For this test I will be using the PW tranceiver over the transmitter because it has an antenna for longer range. also I will be setting the PW to manual power, so no TTL.

PW flex range
YN RF-603 range

RF-603 vs PWflex range mapI was not sure if it is because of the complex signals that the PW use, but the Yongnuo easily outranges the PW. The Yongnuo has been nothing but reliable, great range, but my only complain about it is the lack of lock on the foot, it sometimes drops or will not seat and contact well because of this.

More to come

Total Lunar Eclipse as seen in the Philippines

Stayed up late last night to document the lunar eclipse. It was clear skies all through out the first part of the eclipse but got covered by thick clouds on the peak of it, i did not get to shoot the ending phase.

i just figured out that you cannot shoot the moon using a slow shutter speed, the sucker moves fast, 1sec exposure is enough to blur it
